Hyperbaric nursing as a nursing specialty is a dream we had in June 1985 that became a reality. A specialty that would take an unknown field of nursing and develop an organization for nurses working in the hyperbaric field to create and provide professional support to nurses worldwide, dedicated to offering educational opportunities, support nursing research efforts, have a presence on committees and boards of national organizations, having a public  voice in those issues which impact nursing, and to provide opportunities for networking and information exchange. The dedication and hard work of amazing nurses worldwide over the years has made this possible.

Diane Norkool, one of the first pioneers in this field, provided leadership, research contributions, and educational efforts and was instrumental in developing hyperbaric nursing standards of care, hyperbaric nursing certification and the Baromedical Nurses Association. The Diane Norkool Award was established in 1996 to recognize nurses making a significant contribution to the field of hyperbaric medicine. The recipients of this award to date are:

2017- Richard “Gus” Gustavson

2016- Robin Ortega

2015 – Connie Hutson

2014 – Mary Hirsch

2013 – Ann L. “Tina” Ziemba

2008 – Monica Skarban

2006 – Kathy Furnas

2005 – Susan Churchill

2004 – Laura Josefsen

2002 – Helen Norvell

2001 – Claude Wreford-Brown

1999 – Christy Pirone

1997 – Valerie Larson-Lohr

1996 – Diane Norkool

It is time to start thinking of who should receive this award for 2018! We invite you to think of the efforts of your team members who make a difference in your units and in your practice. Submit your nominations through the BNA website at hyperbaricnurses.org!

As the BNA continues to develop, we wanted to recognize persons outside the nursing realm that make a difference. The Circle of Excellence Award was developed in 2017 to honor individuals who exemplified extraordinary mentoring and/or professional support to promote the mission and vision of hyperbaric nursing, including but not limited to research, education, or safety. The first recipient of this award is Dr. Eugene Worth for his ongoing support and dedication.

Our newest project is the establishment of the first annual Hyperbaric Nurses Day: April 3, 2018 in recognition of the hard work and commitment made each and every day (and sometimes nights!) by all hyperbaric nurses. Visit the BNA website for the many activities and announcements to help promote the hard work you do! There will be live online presentations at the start of the in-service about the history and role of the HBO nurse. (CEU category A). The first part is a tribute to HBO nurses everywhere so please send BNA President Annette (This email address is being protected from spambots. You need JavaScript enabled to view it.) a picture of you and your HBO team, posed or providing care in your facility. We would like to include as many HBO nurses as possible in the presentation.

Join us in our exciting new venture!

Body Language

  • Darren Mazza CHT
  • Volume 09 - Issue 1

New patient education is provided to every patient prior to starting hyperbaric therapy, and being able to communicate with a patient is an absolute must in order to provide a safe treatment. Occasionally an interpreter may be required for patients who speak a primary language other than English, and other patients may be extremely hard of hearing or deaf.

Once the treatment begins, during the descent phase, the pressure differential is significantly increased on the patient’s ears, making it increasingly difficult for the patient to hear the CHT speaking to them. This is the time when good patient communication requirements come into play ensuring the patient is able to both clear their ears and communicate it to the CHT. The CHT always maintains eye contact with the patient during descent. All new patients are instructed to use hand signals in the event they are having trouble clearing their ears during this time.

For 14 years now, I have treated a large number of hyperbaric patients, some of whom have been challenging to communicate with, either because of a language barrier, hearing difficulties, or some medical deficit such as aphasia from a prior CVA. Patient body language is extremely important to observe during a hyperbaric treatment. One recent example was with a patient who did not speak English. The patient became a bit restless during treatment and pulled his blankets off. Although it was quite obvious the patient was over heating, I have also seen patients do this when they are experiencing confinement anxiety.  I used a hand gesture to the patient simulating it was hot by wiping my forehead. The patient then nodded and gave me a thumbs up! I then increased the ventilation rate and cooled the patient down.

Now it’s not always this simple. There was another incident where a patient urgently needed something during the treatment but did not speak English, making it very difficult for the patient to communicate with me! I couldn’t tell if the patient was ill or something else was wrong. The patient didn’t seem to be in a lot of distress but needed something urgently. I ended the treatment and gave the patient the hand signal that he was coming up. The patient nodded in acknowledgment. During the ascent, I motioned to the patient by rubbing my abdomen in an effort to illustrate having an upset stomach. The patient nodded with a big smile. I said to myself that’s what he’s needing, and as soon as the patient was at surface, I slid the gurney out and put the rail down. The patient jumped up and ran to the restroom.

Take-Home Message

The hyperbaric patient is completely dependent on the CHT while in the chamber, from temperature control through ventilation rates to TV channels and volume. Paying close attention to a patient’s body language will provide many clues as to the needs of each patient. Sometimes patients don’t or can’t communicate their every need. It’s up to us to stay alert and keep the patient both comfortable and safe.

Respiratory Therapists and the Hyperbaric Medicine Service

  • Jeff Mize RRT, CHT, CWCA
  • Volume 09 - Issue 1

The use of a respiratory therapist in the hyperbaric medicine department is essential for the care of patients requiring mechanical ventilation. This is a common standard in facilities that provide 24/7 service for emergent indication(s) and the critically ill hyperbaric patients.

As health care evolves, so has the role of every health-care professional. That has certainly been the case with the role and impact of the respiratory therapist in the field of hyperbaric medicine and wound care.

Respiratory therapist involvement in the hospital setting has long been that of a valued component on code blue and emergency response teams. We probably have all experienced the situation of a code blue being called and a seemingly endless number of respiratory therapists respond. It this eagerness and desire to be involved in all aspects of patient care that make a respiratory therapist well suited for the role of hyperbaric technologist.

The core curriculum for respiratory therapy education emphasizes physics and gas laws as the foundation in the development of the students’ clinical knowledge base. While it is obvious that a great understanding of physics and gas laws is necessary for anyone working the field of hyperbaric medicine, what is often overlooked for the hyperbaric tech is the clinical skill set, scope of practice and licensure to provide patient care. The reality every department is faced with is the ability to produce more with fewer resources . . . FTEs.

State licensure and practice scope for a respiratory therapist varies from state-to-state.  Over time a significant change in the opportunities and utilization of respiratory therapists in all areas of patient care has occurred. For example, in addition to the traditional responsibilities, qualified therapists perform arterial-line insertion, emergency intubation, and bedside hemodynamic monitoring. This, of course, is dependent on the individual state and institutional scope of practice.

Educational Requirements

All states that license respiratory therapists require license candidates to complete an accredited degree program in respiratory care recognized by the Commission on Accreditation for Respiratory Care (CoARC). To date, there are 441 accredited CoARC programs across the U.S. Nearly all states have at least one campus location that houses a CoARC-accredited program.

The minimum requirement for licensure in all states where license respiratory therapists is an associate’s degree including two full academic calendar years of study and a clinical experience. Bachelor’s degree programs, however, are gaining in popularity to meet the demand of today’s employers, many of which look for respiratory therapists with more advanced education.(1)

Respiratory Therapist Certification Requirements

National certification through the National Board for Respiratory Care, Inc. (NBRC) is a standard requirement and the basis for licensing among all state boards of respiratory care.

Respiratory therapists also frequently choose to pursue the registered respiratory therapist (RRT) credential, the advanced-level credential in the field of respiratory care. As of January 2015, the RRT credential became the standard for licensing in Ohio and California, and other states are likely to follow suit in the coming years. Many employers are now demanding that candidates for respiratory therapy jobs possess the RRT credential. The Bureau of Labor Statistics reports that many employers are now seeking respiratory therapists who hold bachelor’s degrees in respiratory care.

Among the 8,132 graduates of CoARC-accredited programs in 2012, 89.6 earned an associate degree, a 1% decrease from 2011 and a 5% increase from 2010. Another 10.4% of the graduates in 2012 earned a bachelor’s degree, a 30.3% increase since 2011 and a 9.6% increase since 2010. This highlights the trend toward bachelor’s degrees in the profession.

Occupational Outlook

The median annual wage for respiratory therapists was $58,670 in May 2016. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10% earned less than $42,490, and the highest 10% earned more than $81,550.

In May 2016, the median annual wages for respiratory therapists in the top industries in which they worked were as follows:(2)

 

Nursing care facilities (skilled nursing facilities $59,860
Offices of physicians $59,150
Hospitals; state, local, and private $58,740

The complexities and challenges of patient care and the management of health-care services require, perhaps more than ever, multidiscipline teams. This is evident in the field of hyperbaric medicine. Respiratory therapists interested in the hyperbaric medicine field have opportunity for professional growth as well as the chance for lasting impact on the profession of respiratory care.

Diving with Disabilities - Part 1

  • Michael B. Strauss, MD, Lientra Q. Lu, BS
  • Volume 09 - Issue 1

This article, extracted from a chapter in the second edition of Diving Science by Michael B. Strauss, MD, is an excerpt from Part III of the text revision, which covers special diving types, situations and environments. This current article includes introductory information and definitions in addition to cardiovascular and endocrine-metabolic disabilities.

Other articles in the three-part series to be published in subsequent issues of WCHM will deal with other organ system disabilities, disabilities from previous medical problems of diving, plus a section on organizations and agencies which provide support for divers with disabilities.

Introduction and Defining Disabilities

The Scope of Handicaps The marvels of scuba diving have the potential for greatly enhancing the psychological as well as the physical well being of those with handicaps. Disabilities and handicaps are related terms (Figure 1).

FIGURE 1. Disability Versus Handicap

 

Diving-figure1

Disability and handicap are similar terms, but each has special connotations. There are many related terms associated with these words. The word handicap is not in vogue at this time, being somewhat "politically" incorrect. The highlighted boxes are definitions for each term that best pertain to SCUBA divers

They can refer to a physical condition that makes ordinary activities more difficult, something that causes unusual difficulties with particular activities, or something that gives others an advantage due to the condition. All have implications for the handicapped scuba diver. Many, if not all of the conditions discussed in this chapter are mentioned in other chapters of this text. For example, in the young and the older diver chapters, the subject of disabilities and diving with medical conditions was mentioned. This chapter is a more comprehensive examination of disabilities as they pertain to scuba divers and is organized by body organ systems considered in alphabetical order. This organization minimizes the assumption that one may assume that the first problems mentioned are the most important.

In the 1970s there was much activism in the United States regarding making accommodations for those with handicaps. In 1990 the Americans with Disabilities Act was passed as a law. Among other things it required accommodations be made for those with handicaps such as bathroom facilities and entry ramps as well as companies with multiple employees to hire a percentage of them with handicaps.
Public awareness of handicaps is reflected in a variety of ways such as Paralympic Games, handicap parking availability, new and remodeled commercial construction must have bathroom accommodations for handicapped persons and access to work spaces.
The injuries causing disabilities from our current Middle East military activities has brought heightened awareness to the war-injured veteran with major attention being given to Wounded Warrior Programs. Sports activity participation is a major component of the rehabilitation for these groups, and scuba diving is one of the sports activities in which the wounded warrior can participate.

Uniqueness The aquatic environment is so different from the terrestrial environment that it offers those with handicaps a “new world” of experiences (Table 1). The density of water being over 700 times greater than that of air provides buoyancy and helps counter effects of gravity for those with missing extremities, weakness or traumatic brain injuries. Immersion in the aquatic medium is so different from the air environment that those with post-traumatic stress disorders may well forget their anxieties and depression while submerged. Warm water can add tactile “comfort” unlike any experienced in air. Visualization of the underwater flora and fauna is unique enough that it has the potential for making the handicapped diver feel “special” and something that non-divers are unable to experience.

TABLE 1. Terrestrial versus Aquatic Environments
Items Terrestrial Manifestations Aquatic Manifestations

Comment

(Benefit of the aquatic environment)

Communications Unimpeded Communications by other than verbal means required Compensates for the ability to communicate, such as those with speech impediments, deafness/muteness and autism
Movement of Extremities Not affected Moderates and smoothed-out by the density effect( over 700 times greater than air) of water Possibly compensates for spasticity, tremors, tics, and athetoid movements
Tactile Experiences As they exist Blunted or contraindicated, (i.e. observe but don't touch) Gives clues to the dive buddy how well the handicapped diver follows instructions
Thermal Comfort Controlled with clothing and the excellent insulation effects of air Challenging due to the thermal conductivity (20 times greater than air) and the specific heat (1000 times greater than air) of water The dive organizer/dive buddy must ensure thermal comfort is achieved so as not to lessen the positive dive experience
Visual Experiences As viewed Limited by the density and clarity of water; objects magnified; color expression lost with descents A new experience for the handicapped diver who had not dove previously
Weight Direct effect of gravity Nil due to the buoyancy effect of water Helps to compensate for muscle weakness, limb losses, balance and coordination problems

 

Accommodations Since the handicapped diver has disabilities, special accommodations need to be made. These include choosing the ideal diving site commensurate with the diver’s handicaps. Ideally, warm water with good visibility and optimal diver support services such as trained dive boat personnel and user-friendly entry and exit ramps should be selected for the diving sites. As in all scuba diving activities, but even more important for the handicapped diver, dive planning is essential. The goals are to maximize the experience while minimizing the hazards. Finally, and most importantly, the handicapped diver requires a dive buddy who is aware of and understands the disabled diver’s handicaps, is fit and experienced enough to handle emergency situations for the handicapped diver, and who is willing to give full attention to the handicapped diver to maximize the diver’s experiences while sublimating his/her own. The buddy must have full control of the situation and know when to “call it quits” or not allow the handicap diver to continue with or even do the dive.

Of all the considerations for the handicapped diver, the dive buddy is undoubtedly the most important. Without a knowledgeable and competent dive buddy, the handicap diver should not engage in scuba diving activities. The buddy needs to be dedicated to make the handicapped diver’s experiences as safe and enjoyable as possible. The buddy is also responsible for the decision about when to not dive or to prematurely terminate the dive.

A Tool for Assessing Wellness In managing our wound care patients we use a quick survey to assess their wellness; it was previously described in the older age diver chapter (Table 2).¹  This tool can be easily applied to the handicapped individual who wants to scuba dive. Five assessments related to health and vitality are graded on a 2-point (ideal situation) to 0-point (worst possible situation) scale. The five assessments are: 1) Ability to do activities of daily living, 2) Mobility, 3) Comorbidities, 4) Smoking/ immunosuppressor history and 5) Neurological deficits. When they generate a 0 to 10-point Score. Low (0 to 3 point) scores justify absolute contraindications for scuba diving. Intermediate scores (3½ to 7 points) are relative contraindications to diving and require medical evaluation and clearance for diving. High score (7½ to 10 points) quantify the diver as “healthy” and generally quantify them as able to scuba dive without restrictions. The remainder of this chapter describes how disabilities as occurring in body systems impose handicaps on divers.

TABLE 2. The Wellness Score and Its Usefulness for Making Recommendations about Diving Disabilities

table-2

Key: ADL = Activities of daily living, Im-Sups = Immunosuppressors (e.g. steroids, anti-metabolites, anti-rejection meds)

 

Cardiovascular Disabilities

Conditions Cardiovascular disabilities are associated with the heart muscle blood supply, heart muscle function, heart rhythms and circulation to other parts of the body (Figure 2, Table 3). If one or more of these conditions are present, scuba diving becomes a relative or an absolute contraindication for diving depending on the severity. If any are present, the potential diver requires a cardiac clearance before scuba diving. Invariably, this group of potential scuba divers would have Wellness Scores in the impaired range (3 ½ to 7 points) range. Those with decompensating conditions (Wellness Scores in the 0- to 3-point range) would probably not seek to scuba dive because of the severity of their medical problems.

Metabolic equivalents (METS) is a measure that can be used to quantify fitness. It reflects the amount of oxygen uptake per kilogram of body weight per minute. This is equivalent to utilizing 1 calorie per kilogram (2.2 pounds) of body weight per minute. While sitting, the value is 3.5 METS.
For usual and customary diving activities 7.5 METS are needed.³ This value is about equal to walking at a comfortable pace. However, during emergencies this value may double and accounts for Bove’s recommendation for divers to be able to perform at 14 METS of activity. This would be equivalent to running 8-minute miles (1.6 kilometers).
Bove’s recommendations are probably unrealistic for almost all diving activities and probably unobtainable in those with cardiovascular disease. To mitigate this discrepancy the cardiac handicapped diver needs to dive in “ideal” conditions where the METs activity can be kept in the 7 range.

 

 

FIGURE 2. Heart considerations that can have ramifications for divers

FIGURE-2

Four considerations are the most frequent that raise questions about heart disabilities and diving. Often combinations of these are present in the patient. All have interventions that can help in their management and contribute to making decisions about diving.

 

Evaluations and Clearances Tests such as electrocardiograms (ECGs), echo cardiograms, stress EKGs and/or coronary angiography may be required to ascertain the severity of the heart disease and make the best possible decision whether or not to “clear” the individual for scuba diving. As part of the cardiac clearance, recommendations should be made for an exercise/fitness program. If OK’d for diving, then the potential diver should be referred to a diving medicine physician for a secondary clearance and advice for diving with the disability. The advice is mostly common sense but should include recommendations for maximum depths of diving, how to choose “ideal” diving sites and conditions, the selection of conservative dive settings on the computer, reinforcement of ascent rates and necessity of the rest stop, and importance of maintaining fitness/ cardiac conditioning.

A guideline for cardiac conditioning (cardio) exercises is to pair the person’s age with the pulse rate. This formula for the maximum recommended exertion during cardio exercises is determined by subtracting the person’s age from 220. For example, the maximum heart rate limit during peak cardio exercises for a 60-year-old person would be 160 (i.e. 220 - 60 = 160).
Typically during a cardio exercise program, the goal would be to exercise for brief periods (e.g. 1-minute intervals) up to 90% of recommended maximal heart rate and for longer, more sustained cardio exercise periods at a 75% level.
For the interested, the heart rate during exercise activities (as well as stresses) divided by the maximally recommended heart rate for the person’s age can be expressed as an easily calculated percentage. For example, walking might push up the 60-year-old’s heart rate from 80 to 100. This computes (100/160 = O.625) to exercising at a 62.5% of the maximally recommended exertion (MRE) level. An activity that raises the 60-year- old’s heart rate to 120 would represent exercising at the 75% MRE level.

Patent Foramen Ovale The foramen ovale is an opening in the septum between the right and left atria of the heart that is necessary for circulation through the heart of the fetus. It typically closes at birth, but in about 25 percent of the population it remains partially or fully patent.5 Ordinarily this anomaly goes unnoticed. However, venous gas bubbles that are thought to be a universal finding with ascents from compressed gas diving may bypass the lungs (which filter out the bubbles) and pass into the left side of the heart (Figure 2). The bubbles, in turn, can be carried to the brain and heart as well as other organs and occlude circulation to these structures.

If an apparently “undeserved” case of decompression sickness occurs and involves the brain or heart, a patent foramen ovale (PFO) should be suspected.6 A bubble study with Doppler can document the presence of a PFO. Options after identification include cessation of scuba diving or using the percutaneous technique to patch the PFO. If successful, as is usually the case, the PFO patient may resume scuba diving.

Anticoagulants, Pacemakers and Scuba Diving Anticoagulants are prescribed for patients with atrial fibrillation (irregular heart rates) and after coronary stenting/ angioplasty. Scuba diving per se is not an absolute contraindication for patients using anticoagulants. The major concern is uncontrollable bleeding from injuries from shark bites or other marine animals and lacerations from obstacles in the water or boat propellers. Since these occurrences are extremely rare, the really important considerations are the patient’s cardiac function and fitness. This places the diver who is on anticoagulants in the same relative contraindication for scuba diving category as described above for heart disease. Recommendations for medical clearances to dive and selection of “ideal” diving sites are consequently the same.

Similar advice is appropriate  for scuba diving with pacemakers. Diving with pacemakers is another relative contraindication. In addition to the reason for the pacemaker and the patient’s cardiac function, the pressure/ depth limit of the pacemaker needs to be as certained. Usually pacemaker pressure/depth limit information is available from the manufacturer of the pacemaker. One study showed pacemakers continued to function to 100 FSW/30 MSW depths. Those peacemakers that are implantable cardioverter defibrillators (ICDs) are in our opinion an absolute contraindication for scuba diving. Typically, they have a low voltage electrical discharge for mitigating slowed heart rhythms and a high voltage shock for life threatening rhythms such as ventricular fibrillation (VF).

TABLE 3. Cardiovascular Disabilities and Diving
Problem Effect Scuba Diving Ramifications
Blood Supply (Coronary Artery Disease) Interferes with heart muscle oxygenation, carbon dioxide removal and nutrition Heart attack with death of cardiac muscle limits cardiac output
Heart Muscle Function (Cardiomyopathies such as hypertrophic, restrictive, dilated from alcohol, cocaine, amyloidosis, hemochromatosis, coronary artery disease, heavy metals, etc.) Loss of heart contractile power and/or ability Impaired cardiac output makes patient unable to meet demands of exercise

Heart Rhythm Irregularities (Atrial fibrillation, atrial flutter, bradycardia, tachycardia, ventricular fibrillation)

Interferes with heart filing and blood outflow Water immersion, especially if cold precipitates arrhythmias, specifically bradycardia (Ref.2)
Circulation to Body Parts (Peripheral artery disease) Inadequate perfusion to supply oxygen and metabolites to muscles and other body organs Pain, weakness, and/or cramping with muscle ability. Limited ability to increase muscle activity for responses to emergencies

If the patient is at risk for VF and associated loss of consciousness in the water, even if only temporary, the consequences can be disastrous with water aspiration, near-drowning and drowning. Other absolute contraindications for scuba diving with pacemakers exist for commercial, scientific and military activities.

Other considerations are whether the high voltage of the ICD will be influenced by the electrical conductivity of the surrounding sea water and whether or not the electrical discharge will shock other divers who are in contact with or close vicinity of the diver receiving the ICD shock. The answers to these provocative considerations are not known to the authors.

Peripheral Artery Disease It is unusual for this problem to be a consideration for scuba diving. If severe enough, the patient most likely is already limiting his/her activities and scuba diving is not a consideration. If mild, but claudication (i.e. ischemic leg or thigh cramping-like pain) is observed with walking, the patient may be able to swim without symptoms. However, the use of fins, especially if needed for fast swimming and/ or emergencies, may precipitate claudication and compound the problem, that is the cramping will cause cessation of swimming activities and compromise extrication from the emergency. Hence, scuba diving is not recommended for such patients. Interventions such as bypass surgery, angioplasties and/or stenting are effective in managing peripheral artery disease and if successful, elevate an absolute to a relative contraindication for diving.

As is typical with peripheral artery disease, other significant comorbidities are likely to co-exist. The Wellness Score can alert those making decisions for diving whether the patient with a peripheral artery disease history, whether treated or not, should be medically cleared for scuba diving. Other assessments such as mobility and neurological impairments of the Wellness Score are likely to be the limiting factors in making decisions about scuba diving.

The foramen ovale is a physiological structure in the IAS that allows oxygen blood from the placenta to be circulated to the fetus. At birth it closes spontaneously in about 75% of the newborns. In the 25% where it remains open, it can be a cause of venous gas emboli by passing the lungs and moving to the arterial circulation.

Endocrine and Metabolic Considerations

Diabetes Mellitus and Obesity The two main endocrine metabolic disorders with respect to scuba diving are diabetes mellitus (DM) and obesity. However, other endocrine gland functions also have some relevance to scuba diving (Table 4). The main concerns with DM is that the diver may become hypoglycemic during the scuba dive, become confused and even lose consciousness while underwater. Both are situations that may require emergency ascents and lead to arterial gas embolism or decompression sickness or if consciousness is lost, drowning. However, there are guidelines in the literature that embrace scuba diving in the diabetic even if the patient is insulin dependent.8,9

There is a wide spectrum of DM manifestations that range from only borderline blood sugar elevations to very labile cases. The labile diabetic may be confronted with hyperglycemia and ketoacidosis, which can be life threatening, alternating with hypoglycemia that can lead to unconsciousness and death of brain tissues.
Diabetics are classified as Type 1, that is insulin dependent, and Type 2 non-insulin dependent. In Type 1 the pancreas has lost all of its ability to produce insulin, the hormone required for blood sugar (glucose) to be transported into the cell. Without insulin, the fuel source (glucose) for cell metabolism and energy production does not reach these organelles (mitochondria) where these processes occur and the cell stops functioning, just as an automobile stops running after running out of gas.
Medications can modify Type 2 DM by stimulating the pancreas to secrete more insulin, improving the transport of insulin across the cell wall, or combinations of these.
 

Considerations for scuba diving with diabetes include that the patient has a history of stable blood sugars and is compliant with his/her diabetes management as reflected in glycosylated hemoglobins (HgA1c) in the six percent or less range. Blood glucoses should be measured immediately before starting the scuba dive and at the dive’s termination. This reflects a proactive approach to avoiding hypoglycemia during the course of and immediately after the dive. Emergency glucose sources in a diver’s buoyancy compensator pouch should be available in case precursor symptoms of hypoglycemia such as lightheadedness, sweating, or weakness are noted during the dive. Of course the dive should be planned to minimize stresses with the measures mentioned previously.

Obesity Obesity imposes relative contraindications for scuba diving. It is a generic term that represents a spectrum of findings from being mildly overweight to morbid obesity. The body mass index (BMI) is used to gauge obesity. Over weightiness is defined as a BMI greater than 25, obesity greater than 30, and morbid obesity as a BMI greater than 40. Another measure of morbid obesity is a body weight of 100 pounds (45 kilograms) over ideal body weight, that is a body weight in the 20 to 25 BMI range.

The BMI is a simple ratio calculated by dividing the patient’s weight by his/ her height. Factors that can confuse the interpretation of the BMI include excessive abdominal fat, extremely well developed musculature as in body builders, and fluid retention in lower extremities secondary to lymphedema

Two major considerations are associated with obesity and scuba diving. The first is an increased propensity for developing decompression sickness.10 This is attributed to fat tissues having five times the affinity for nitrogen than the surrounding tissue fluids of the body. Fat is considered an intermediate tissue with respect to ongassing and offgassing due to a highly regulated (by sympathetic nervous system) blood supply. With longer, deeper dives increased ongassing occurs in this tissue. If ascent and offgassing is based on tissues that offload nitrogen faster than the nitrogen saturated fat tissues, sufficient gradients may develop to generate bubbles and lead to decompression sickness symptoms.

FIGURE 4. Endocrine Glands and Their Implications for Diving

FIGURE-4

Although endocrine gland functions are rarely associated with diving, their "silent" functions contribute much to making the dive safe and comfortable. When their functions are hampered or absent, they can be absolute contraindications for diving.

The other major consideration for the obese diver is fitting of equipment. The obese diver will require substantially more weights for buoyancy control. This coupled with the buoyancy of ¾-inch (7 mil) thick neoprene wetsuit can result in requiring 40 to 50 pounds (18 to 23 kilograms) of weights to achieve neutral buoyancy. This added weight makes water entries and exits as well as rescue efforts if an emergency develops challenging. The extra exertion required could subject the obese diver to cardiac events. Other medical problems are frequent in the obese diver including the metabolic syndrome (hypertension, hyperlipidemia [increased triglycerides—i.e. bad cholesterol], increased blood glucose, increased abdominal girth, and low levels of high density lipoproteins [i.e. good cholesterol]; arthritis from overloading joints from the added body weight; obstructive sleep apnea; gastrointestinal reflux disease; depression; infertility; and incontinence). If the obese diver is determined to scuba dive, he/she should be motivated enough to lose weight and optimize the medical management of existing comorbidities. Over weightiness is a reason for disqualification of military divers.

Alcohol The social use of alcohol is not a contraindication for scuba diving. However, it should not be consumed before a scuba dive. It can blunt judgment and may compound the effects of nitrogen narcosis and can occur in situations where it ordinarily would not. Those with alcohol dependence (i.e. alcoholics) should not scuba dive until they have been detoxed and can be labeled as recovered. Another consideration about immediate alcohol use before a scuba dive is that it is a diuretic (stimulates the production of urine). This can contribute to dehydration and, in turn, interfere with the circulation system’s ability to offload nitrogen during the ascent phase of the dive. These events may be precursors to decompression sickness.

Pituitary "Master" control gland; sends hormonal signals to other glands to increase or decrease their activity; regulates growth Management can be challenging and requires medications for loss of function of all the pituitary target glands Absent function is an absolute contraindication for diving – if insufficient function it becomes a relative contraindication
Thyroid Regulates metabolism If hypofunctioning it can lead to poor cold-water tolerance, weight gain, and delayed responsiveness (e.g. excessive tiredness). If hyperexcitability, tachycardia, weight loss, and heat intolerance Thyroid problems when well controlled with medications do not present a contraindications for diving
Islets Cells of Pancreas Generate insulin and control its release (with signals from blood glucose and pituitary gland) See previous discussion on diabetes in this section Diabetes imposes relative contraindications for diving
Adrenal Releases "flight or fight" hormones (adrenalin and noraadrenalin) as well as cortisol, which affects blood pressure, glucose, growth, and sexual characteristics If non-functional, ability for a diver to response to a crisis may be impaired If function is impaired, medial clearance for diving needed from an endocrinologist as well as a diving medicine physician. If cleared, diving should be done in "ideal" conditions
Ovaries and Testes Both produce testosterone (a third more in males) plus regulate reproductive tissue Over production may contribute to "macho" action of the diver, underactivity may lead to lethargy, depression, and muscle weakness Malfunction or absence probably present no contraindications for scuba diving

Because of the durations and intensities of commercial divers’ underwater activities, they often develop joint pain presentations of decompression sickness.
In attempts to stop the divers drinking alcohol to mitigate their symptoms after the dive, they were told to report their symptoms immediately and then undergo hyperbaric oxygen recompression. With this protocol after becoming asymptomatic, they could resume diving activities the next day.11
Prior to implementing this, the divers were taken “off station” which resulted in substantial losses of income and explained why they were reluctant to complain about their joint pain symptoms — and used drinking alcohol to mask them.
The immediate treatment had twofold benefits. It relieved symptoms and allowed the immediate resumption of diving activities. Possible long-term benefits may include prevention of delayed bone necrosis of the hips and shoulders and multiple sclerosis plaques in the brain and spinal cord tissues, both of which are thought to be related to omitted decompression and/or repeated episodes of decompression sickness.


Other Metabolic Considerations Almost all endocrine disorders have ramifications for scuba diving (Table 4). However, if mild or easily controlled with medications, they do not impose contraindications to scuba diving. If severe, they provide absolute contraindications for diving. Thyroid disease is the most controllable of all endocrine disorders. When properly managed, it imposes no restrictions for scuba diving. Steroids and other immune suppressors have ramifications for divers. Their use is a relative contraction for scuba diving. They blunt the body’s inflammatory responses and weaken the immune system. A short course of steroids (e.g. Medrol DosPak®) to control an acute inflammatory condition imposes only a temporary contraindication to diving. Chronic use of steroids for asthma, colitis, or collagen vascular diseases is a contraindication for scuba diving. The steroids blunt the adrenal response to stress; however, probably more importantly the reason chronic steroid use is required is the stronger reason for not scuba diving. Although pregnancy is a temporary contraindication for scuba diving, lactation in the female diver is not. Viagra® and related medications do not seem to interfere with diving. Some information, anecdotal at this time, suggest it may lessen the chances of decompression sickness occurring.

The Spinning World of Coding Updates

  • Gretchen Dixon
  • Volume 09 - Issue 1

Have you reviewed the added wound severity codes effective October 1, 2017? Do you sometimes second guess the diagnosis codes selected? Do the codes accurately reflect the patient’s medical condition? Are you comfortable the claim will not hit any edits and reimbursement will be timely? You may answer yes, no, maybe or doubt sets in with a big question mark of “am I sure?”. Here are some updates and changes to wound care diagnosis ICD-10 diagnosis codes.

For the fiscal year of 2018 starting October 1, 2017, the Cooperating Parties [the American Hospital Association (AHA), the American Health Information Management Association (AHIMA), Centers for Medicare and Medicaid Services (CMS), and National /Center for Health Statistics (NCHS)] for the ICD-10-CM approved expanding the category for non-pressure chronic ulcers is a positive change. Notice the new options of choosing a code with or without necrosis of muscle or bone. This article will focus on the added new codes (63) with descriptions stating “without evidence of necrosis . . .” providing a more accurate acuity level, complexity of care and intensity of services provide in wound care. The category of L97 titled Non-Pressure Chronic Ulcer of Lower Limb, not elsewhere classified, includes the following descriptions:

  • Chronic ulcer of skin of lower limb NOS (not otherwise specified)

  • Non-healing ulcer of skin

  • Non-infected sinus of skin

  • Trophic ulcer NOS

  • Tropical ulcer NOS

  • Ulcer of skin lower limb NOS

Within the ICD-10 coding manual for this code family L97, there are specific coding directions involving underlying medical conditions and the hierarchy of code reporting these diagnoses. Under this family, the anatomy hierarchy includes laterality (unspecified, right or left respectively) and begins with the L97.1 Non-Pressure Chronic Ulcer of Thigh and ending with the last L97.92 Non-Pressure Chronic Ulcer of Unspecified Part of Left Lower Leg. All of these specific codes require a total of 6 characters for completeness. The following charts include samples of the new codes and description changes noted in red which must be supported with clinical documentation. However, due to the numerous codes, refer to your 2018 ICD-10-CM Coding Manual for the complete listing beginning with L97.101 through L97.629.

NOTE: In the wound care setting, there never should be ICD-10 codes selected with the term unspecified severity. The ICD-10 diagnosis codes to watch for end with the number “9” such as code L97.329 Non-Pressure Chronic Ulcer of Left Ankle with Unspecified Severity.

Coding Question Related to Radiation Late Effects or Complications

Proctitis:

Radiation proctitis or colitis seems to be an issue for Medicare claim reporting with ICD-10 hierarchy. Based on CMS transmittals and websites for hyperbaric oxygen Therapy (HBOT), there is a coding hierarchy which will need to be followed to prevent claim edits. ICD-10 code L59.8– Other Specified Disorders of the Skin and Subcutaneous Tissues Related to Radiation will need to be listed as the first or principle diagnosis code. The reason for this is CMS has clearly documented this diagnosis as a covered diagnosis.

Adding ICD-10 diagnosis codes K52.0 – Gastroenteritis and Colitis Due to Radiation or K62.7 – Radiation Proctitis as Secondary Diagnoses should provide additional support for the designed treatment plan. In the coding manual, the coder is directed to select an additional code to identify the type of radiation; therefore, clinical documentation history needs to provide details of the past radiation treatment regime.

Unfortunately, even though the code selection may not make sense to us, as coders we must follow the various third-party payers such Medicare for their unique coding and billing requirements to the best of our ability.

Here is the access to the most current Centers of Medicare and Medicaid Services HBO spreadsheet regarding covered diagnosis as of October 30, 2017, for your reference: https://www.cms.gov/Regulations-and-Guidance/ Transmittals/2017Downloads/R1975OTN.pdf

With the above stated, this is an example of how the codes should be reported; however, understand there is no guarantee even this hierarchy would be accepted. Patient history notes history of adenocarcinoma of prostate, treated with radioactive seed implants 24 months ago, presents with diagnosis of proctitis due to radiation therapy and severe pelvic pain. What is missing is the other details on the type, number and length of treatment with radioactive seed implants.

Principle Diagnosis Secondary Diagnoses

L59.8 - Other Specified Disorders of the Skin and Subcutaneous Tissues Related to Radiation

 

 

 

 

K62.7 - Radiation Proctitis

R10.2 - Pelvic and Perineal Pain

Z85.46 - Personal History of Malignant Neoplasm of Prostate

Y84.2 - Radiological Procedure and Radiotherapy as the Cause of Abnormal Reaction of the Patient, or of Later Complication, without Mention of Misadventure at the Time of the Procedure

 

Skin Grafts Versus Tissue Grafts Clarification

There have been some questions circulating in our industry about the term skin graft being documented on the HBO2 evaluation. However, the clinical documentation references note the patient received a tissue graft and within a few hours of the surgical procedure, the tissue graft was compromised with a change in color from pink to turning dusky. 

This was a sign the tissue graft was compromised and needed immediately post-surgical intervention with hyperbaric medicine therapy.

First review the definition of both skin graft and graft or tissue flap/ graft. A skin graft is a thin sheet of skin harvested from a donor site creating two possible wound care sites.

Skin graft is a surgical procedure involving harvesting a sheet of healthy skin from an area of the body and transplanting it to a different part of the body to provide a protective covering of an area missing normal skin. The skin graft may consist of partial or full thickness to replace damaged layers of the skin.

This may be due to burns, injury or an illness.  A partial or split thickness skin graft contains the epidermis and part of the dermis layer of skin tissue where as a full thickness skin graft contains the epidermis and entire thickness of the dermis.

A tissue flap is tissue transferred with its own blood supply intact from one area of the body to another area of the body. A flap is attached to the body by an artery or vein at its base to be used for reconstructive surgery repairing a large defect deeper than the top layers of the skin. There are two different surgical methods:

  • Pedicle flap means the flap of tissue from the back or belly is moved to the chest without cutting its original blood supply. The tissue is pulled under the skin up to the chest area and attached.
  • Free flap means the tissue and blood vessels are cut. After the flap is in place, the surgeon sews the blood vessels in the flap to blood vessels in the body chest. This requires microscopic surgery to anastomose the blood vessels from the donor tissue to the recipient tissues.

A tissue graft is a transfer of tissue mass without its own blood supply and depends entirely on the blood supply from the recipient site for growth of new blood vessels.

In summarization, a tissue flap has its own blood supply and a graft does not, requiring a good vascular bed at the site to survive.

Complications post-surgical flap or graft present with ischemia, change in skin temperature, skin or fat necrosis, venous congestion or occlusion, arterial occlusion or mechanical meaning there is no overt explanation. Clinical documentation must include details of the situation in the history of present illness (HPI) to support the medical necessity of trying to salvage the flap or graft.

A statement by the provider needs to include the following details in the HPI:

  • Prior surgical interventions: patient response with outcomes
  • Date when hypoxia or decreased perfusion was identified as compromising the viability of the flap or graft
  • Identify any prior adjunctive treatments performed with responses
  • Identify any comorbidities which may need intervention pre-hyperbaric therapy

The following is a sample statement that wraps up the elements noted in the HPI, summarizing the appropriateness of HBO2:

“The viability of the graft’s survival appears threatened due to a mechanical complication. HBOT during this immediate post-operative period may improve the survival of the flap with the increased perfusion of oxygen.”

There are four (4) ICD-10 diagnosis codes CMS lists in their above Excel spreadsheet supporting these complications for both tissue flap or tissue graft located under skin graft or skin terms as follows:

Skin graft (allograft): Rejection T86.820

                                  Failure T86.821

                                  Infection T86.822

                                  Other complications of skin graft (allograft, autograph) T86.828

Compliance Wrap-Up

Wound care is under intense scrutiny today, especially hyperbaric medicine. Therefore, providers need to invest by reviewing their own current clinical documentation and identify weaknesses in the details thus making improvements to support medical necessity through a clear and consistent clinical rationale for hyperbaric therapy. The ICD-10 diagnosis codes listed in this article provide an overview of the level of detail required in history of present illness section of the clinical documentation to support selection of diagnosis codes at their highest level of specificity. Keep in mind the bottom line is all submitted diagnosis codes provide the third-party payer a “picture” of the patient’s medically complex condition(s) for treatment within the wound care setting. If your diagnosis codes are without specificity, then you risk either a claim held for additional information or possibly a denied claim resulting in a negative toward your department’s financial viability.
