A recompression chamber is used to treat some diving disorders, and for training divers to recognise the symptoms.

Diving medicine, also called undersea and hyperbaric medicine (UHB), is the diagnosis, treatment and prevention of conditions caused by humans entering the undersea environment. It includes the effects on the body of pressure on gases, the diagnosis and treatment of conditions caused by marine hazards and how relationships of a diver's fitness to dive affect a diver's safety.

Hyperbaric medicine is a corollary field associated with diving, since recompression in a hyperbaric chamber is used as a treatment for two of the most significant diving related illnesses, decompression illness and arterial gas embolism.

Diving medicine deals with medical research on issues of diving, the prevention of diving disorders, treatment of diving accidents and diving fitness. The field includes the effect of breathing gases and their contaminants under high pressure on the human body and the relationship between the state of physical and psychological health of the diver and safety.

In diving accidents it is common for multiple disorders to occur together and interact with each other, both causatively and as complications.

Diving medicine is a branch of occupational medicine and sports medicine, and an important part of diver education.

Range and scope of diving medicine

Template:Further The scope of diving medicine must necessarily include conditions that are specifically connected with the activity of diving, and not found in other contexts, but this categorization excludes almost everything, leaving only deep water blackout, isobaric counterdiffusion and high pressure nervous syndrome. A more useful grouping is conditions that are associated with exposure to variations of ambient pressure. These conditions are largely shared by aviation and space medicine. Further conditions associated with diving and other aquatic and outdoor activities are commonly included in books which are aimed at the diver, rather than the specialist medical practitioner, as they are useful background to diver first aid training.

The scope of knowledge necessary for a practitioner of diving mediciene includes the medical conditions associated with diving and their treatment, physics and physiology relating to the underwater and pressurised environment, the standard operating procedures and equipment used by divers which can influence the development and management of these conditions, and the specialised equipment used for treatment.

Scope of knowledge for diving medicine

The ECHM-EDTC Educational and Training Standards for Diving and Hyperbaric Medicine (2011) specify the following scope of knowledge for Diving Medicine:[1]



Scope of knowledge for hyperbaric medicine

The ECHM-EDTC Educational and Training Standards for Diving and Hyperbaric Medicine (2011) specify the following scope of knowledge for Hyperbaric Medicine additional to that for Ddiving medicine:[1]

  • Physiology and pathology of diving and hyperbaric exposure.
    • HBO-Basics - effects of hyperbaric oxygen - physiology and pathology
  • Clinical HBO
    • Chamber technique (multiplace, monoplace, transport chambers, wet recompression)
    • Mandatory indications
    • HBO Recommended indications
    • HBO Experimental and anecdotal indications
    • HBO Data collection / statistics / evaluation
    • HBO General basic treatment (nursing)
    • HBO Diagnostic, monitoring and therapeutic devices in chambers
    • Risk assessment, incidents monitoring and safety plan in HBO chambers
    • HBO Safety regulations


The signs and symptoms of diving disorders may present during a dive, on surfacing, or up to several hours after a dive. Divers have to breathe a gas which is at the same pressure as their surroundings, which can be much greater than on the surface. The ambient pressure underwater increases by {{safesubst:#invoke:convert|convert}} for every {{safesubst:#invoke:convert|convert}} of depth.[2]

The principal conditions are: decompression illness (which covers decompression sickness and arterial gas embolism); nitrogen narcosis; high pressure nervous syndrome; oxygen toxicity; and pulmonary barotrauma (burst lung). Although some of these may occur in other settings, they are of particular concern during diving activities.[2]

The disorders are caused by breathing gas at the high pressures encountered at depth, and divers will often breathe a gas mixture different from air to mitigate these effects. Nitrox, which contains more oxygen and less nitrogen is commonly used as a breathing gas to reduce the risk of decompression sickness at recreational depths (up to about {{safesubst:#invoke:convert|convert}}). Helium may be added to reduce the amount of nitrogen and oxygen in the gas mixture when diving deeper, to reduce the effects of narcosis and to avoid the risk of oxygen toxicity. This is complicated at depths beyond about {{safesubst:#invoke:convert|convert}}, because a helium–oxygen mixture (heliox) then causes high pressure nervous syndrome.[2] More exotic mixtures such as hydreliox, a hydrogen–helium–oxygen mixture, are used at extreme depths to counteract this.[3]

Decompression sickness

Decompression sickness (DCS) occurs when gas, which has been breathed under high pressure and dissolved into the body tissues, forms bubbles as the pressure is reduced on ascent from a dive. The results may range from pain in the joints where the bubbles form to blockage of an artery leading to damage to the nervous system, paralysis or death. While bubbles can form anywhere in the body, DCS is most frequently observed in the shoulders, elbows, knees, and ankles. Joint pain occurs in about 90% of DCS cases reported to the U.S. Navy, with neurological symptoms and skin manifestations each present in 10% to 15% of cases. Pulmonary DCS is very rare in divers.[4]

Pulmonary barotrauma and arterial gas embolism

If the breathing gas in a diver's lungs cannot freely escape during an ascent, the lungs may be expanded beyond their compliance, and the lung tissues may rupture, causing pulmonary barotrauma (PBT). The gas may then enter the arterial circulation producing arterial gas embolism (AGE), with effects similar to severe decompression sickness.[5] Gas bubbles within the arterial circulation can block the supply of blood to any part of the body, including the brain, and can therefore manifest a vast variety of symptoms.

Nitrogen narcosis

Nitrogen narcosis is caused by the pressure of dissolved gas in the body and produces impairment to the nervous system. This results in alteration to thought processes and a decrease in the diver's ability to make judgements or calculations. It can also decrease motor skills, and worsen performance in tasks requiring manual dexterity. As depth increases, so does the pressure and hence the severity of the narcosis. The effects may vary widely from individual to individual, and from day to day for the same diver. Because of the perception-altering effects of narcosis, a diver may not be aware of the symptoms, but studies have shown that impairment occurs nevertheless.[6]

High pressure nervous syndrome

Helium is the least narcotic of all gases, and divers may use breathing mixtures containing a proportion of helium for dives exceeding about {{safesubst:#invoke:convert|convert}} deep. In the 1960s it was expected that helium narcosis would begin to become apparent at depths of {{safesubst:#invoke:convert|convert}}. However, it was found that different symptoms, such as tremors, occurred at shallower depths around {{safesubst:#invoke:convert|convert}}. This became known as high pressure nervous syndrome, and its effects are found to result from both the absolute depth and the speed of descent. Although the effects vary from person to person, they are stable and reproducible for the individual.

Oxygen toxicity

Although oxygen is essential to life, in concentrations significantly greater than normal it becomes toxic, overcoming the body's natural defences (antioxidants), and causing cell death in any part of the body. The lungs and brain are particularly affected by high partial pressures of oxygen, such as are encountered in diving. The body can tolerate partial pressures of oxygen around {{safesubst:#invoke:convert|convert}} indefinitely, and up to {{safesubst:#invoke:convert|convert}} for many hours, but higher partial pressures rapidly increase the chance of the most dangerous effect of oxygen toxicity, a convulsion resembling an epileptic seizure.[7] Susceptibility to oxygen toxicity varies dramatically from person to person, and to a smaller extent from day to day for the same diver.[8] Prior to convulsion, several symptoms may be present – most distinctly that of an aura.


Treatment of diving disorders depends on the specific disorder or combination of disorders, but two treatments are commonly associated with first aid and definitive treatment where diving is involved. These are first aid oxygen administration at high concentration, which is seldom contraindicated, and generally recommended as a default option in diving accidents where there is any significant probability of hypoxia, and hyperbaric oxygen therapy, which is the definitive treatment for most incidences of decompression illness. Hyperbaric treatment using other breathing gases is also used for treatment of decompression sickness if HBO is inadequate.

Oxygen therapy

The administration of oxygen as a medical intervention is common in diving medicine, both for first aid and for longer term treatment.

Recompression and hyperbaric oxygen therapy

Recompression treatment in a hyperbaric chamber was initially used as a life-saving tool to treat decompression sickness in caisson workers and divers who stayed too long at depth and developed decompression sickness. Now, it is a highly specialized treatment modality that has been found to be effective in the treatment of many conditions where the administration of oxygen under pressure[9] has been found to be beneficial. Studies have shown it to be quite effective in some 13 indications approved by the Undersea and Hyperbaric Medical Society.[10]

Hyperbaric oxygen treatment is generally preferred when effective, as it is usually a more efficient and lower risk method of reducing symptoms of decompression illness, but in some cases recompression to pressures where oxygen toxicity is unacceptable may be required to eliminate the bubbles in the tissues in severe cases of decompression illness.

Education and registration of practitioners

Specialist training in underwater and hyperbaric medicine is available from several institutions, and registration is possible both with professional associations and governmental registries.


{{#if:||}}NOAA/UHMS Physicians Training Course in Diving Medicine{{#if:||}}
{{#if:|{{{no}}}.  |}}This course has been presented since 1977, and has been influenced by internationally accepted training objectives recommended by the Diving Medical Advisory Committee, the European Diving Technology Committee, and the European Committee for Hyperbaric Medicine. The course is designed for qualified medical practitioners, but may be useful to others who work in the field of diving safety and operations.[11]

The course is to train physicians to recognize and treat diving medical emergencies. Subject matter includes:[11]

  • Basic physics and physiology of the hyperbaric environment:
    • the laws and principles;
    • the differences between hyperbaric and hypobaric pressure;

    • links between the physiological effects of the hyperbaric environment and the pathology of the disease
  • Basic decompression theory:
  • Dive computer theories and types, and comparison to dive tables
  • Introduction to commercial diving and comparison to recreational and technical diving, including differences in procedures, equipment, and diver categories
  • The clinical application of hyperbaric oxygen therapy and the treatment tables used;
  • Participation in surface-supplied diving operation and hyperbaric chamber operations;
  • Components, types, operational and safety hazards associated with hyperbaric chambers;
  • Diving related conditions resulting from the effects of long term effects of diving, flying after diving, altitude, thermal conditions, age and gender
  • Neurologic assessment on a diver with signs and/or symptoms of DCI
  • Medical and fitness standards for diving, including:
    • contraindications for both commercial and recreational divers
    • differences in medical standards for recreational versus occupational diving communities
    • legal implications for approving and denying fitness to dive in an occupational setting
    • approaches for determining the safety of prescription and OTC medications used by divers

{{#if:|{{{no}}}.  |}}The Accreditation Council for Graduate Medical Education (ACGME) and the American Osteopathic Association (AOA) offer 12 month programs in undersea and hyperbaric medicine associated with ACGME or AOA accredited programs in emergency medicine, family medicine, internal medicine, occupational medicine, preventive medicine, or anesthesiology.[12][13][14]

{{#if:||}}ECHM-EDTC Educational and Training Standards for Physicians in Diving and Hyperbaric Medicine{{#if:||}}
{{#if:|{{{no}}}.  |}}The standard drawn up jointly by the European Committee for Hyperbaric Medicine and the European Diving Technical Committee defines job descriptions for several levels of diving and hyperbaric physician: Education and assessment to these standards may be provided by institutions of higher education under the leadership of a Level 3 Hyperbaric Medicine Expert as defined below. Certificates of competence may be issued by a nationally accredited institution or an internationally acknowledged agency, and periodic recertification is required.[1]

Level 1. Medical Examiner of Divers (MED) minimum 28 teaching hours.

  • The MED must be competent to perform the assessments of medical fitness to dive of occupational and recreational divers and compressed air workers, except the assessment of medical fitness to resume diving after major decompression incidents.

Level 2D. Diving Medicine Physician (DMP) minimum 80 teaching hours.

  • A DMP must be competent to perform the initial and all other assessments of medical fitness to dive of working and recreational divers or compressed air workers, and manage diving accidents and advise diving contractors and others on diving medicine and physiology (with the backup of a diving medical expert or consultant).
  • A DMP should have knowledge in relevant aspects of occupational health, but is not required to be a certified specialist in occupational medicine.
  • A DMP should have certified skills and basic practical experience in assessment of medical fitness to dive, management of diving accidents, safety planning for professional diving operations, advanced life support, acute trauma care and general wound care.

Level 2H. Hyperbaric Medicine Physician (HMP) minimum 120 teaching hours

  • An HMP will be responsible for hyperbaric treatment sessions (with the backup of a hyperbaric medicine expert or consultant)
  • An HMP should have appropriate experience in anaesthesia and intensive care in order to manage the HBO patients, but is not required to be a certified specialist in anaesthesia and intensive care.
  • An HMP must be competent to assess and manage clinical patients for hyperbaric oxygen therapy treatment

Level 3. Hyperbaric medicine expert or consultant (hyperbaric and diving medicine) is a physician who has been assessed as competent to:

The American Medical Assocition recognises the sub-speciality Undersea and Hyperbaric Medicine held by someone who is already Board Certified in some other speciality.[18]

The South African Department of Labour registers two levels of Diving Medical Practitioner. Level 1 is qualified to conduct annual examinations and certification of medical fitness to dive, on commercial divers (equivalent to ECHM-EDTC Level 1. Medical Examiner of Divers), and Level 2 is qualified to provide medical advice to a diving contractor and hyperbaric treatment for diving injuries[19] (equivalent to ECHM-EDTC Level 2D Diving Medicine Physician)

Australia has a four tier system: In 2007 there was no recognised equivalence with the European standard.[20]

  • GPs completing the first tier four- to five-day course on how to examine divers for ‘fitness to dive’ can then add their names to the SPUMS Diving Doctors List
  • GPs completing the second tier two-week diving medicine courses provided by the Royal Australian Navy and the Royal Adelaide Hospital, or the two-week course in Diving and Hyperbaric Medicine provided by the ANZ Hyperbaric Medicine Group, qualify to do commercial-diving medicals.
  • The third tier is the SPUMS Diploma in Diving and Hyperbaric Medicine. The candidate must attend a two-week course, write a dissertation related to DHM and have the equivalent of six months’ full-time experience working in a hyperbaric medicine unit.
  • The fourth tier is the Certificate in Diving and Hyperbaric Medicine from the ANZ College of Anaesthetists.

Training of divers and support staff in relevant first aid


A basic knowledge understanding of the causes, symptoms and first aid treatment of diving related disorders is part of the basic training for most recreational and professional divers, both to help the diver avoid the disorders, and to allow appropriate action in case of an incident resulting in injury.

Recreational divers

A recreational diver has the same duty of care to other divers as any ordinary member of the public, and therefore there is no obligation to train recreational divers in first aid or other medical skills. Nevertheless, first aid is training is recommended by most, if not all, recreational diver training agencies.

Recreational diving instructors and divemasters, on the other hand, are to a greater or lesser extent responsible for the safety of divers under their guidance, and therefore are generally required to be trained and certified to some level of rescue and first aid competence, as defined in the relevant training standards of the certifying body. In many cases this includes certification in Cardiopulmonary resuscitation and Oxygen administration for diving accidents.

Professional divers

Professional divers usually operate as members of a team with a duty of care for other members of the team. Divers are expected to act as standby divers for other members of the team and the duties of a standby diver include rescue attempts if the working diver gets into difficulties. Consequently, professional divers are generally required to be trained in fescuoe procedures appropriate to the modes of diving they are certified in, and to administer first aid in emergencies. The specific training, competence and registration for these skills varies, and may be specified by state or national legislation or by industry codes of practice.

Diving supervisors have a similar duty of care, and as they are responsible for operational planning and safety, generally are also expected to mange emergency procedures, including the first aid that may be required. The level of first ait training, competence and certification will generally take this into account.

  • In South Africa, registered commercial and scientific divers must hold current certification in first aid at the national Level 1, with additional training in oxygen administration for diving accidents, and registered diving supervisors must hold Level 2 first aid certification.[19]
  • Offshore diving contractors frequently follow the IMCA recommendations.

Diver Medic

A diver medic is a member of a dive team who is trained in advanced first aid.[21] A Diver Medic recognised by IMCA must be capable of administering First Aid and emergency treatment, and carrying out the directions of a doctor pending the arrival of more skilled medical aid, and therefore must be able to effectively communicate with a doctor who is not on site, and be familiar with diving procedures and compression chamber operation. The Diver Medic must also be able to assist the diving supervisor with decompression procedures provide advice as to when more specialised medical help should be requested, and must be fit to provide treatment in a hyperbaric chamber in an emergency, and must therefore hold a valid certificate of medical fitness to dive.[22]

Training standards for Diver Medic are described in the IMCA Scheme for Recognition of Diver Medic Training.[22]

Featured disease

Metabolic syndrome is a cluster of the most dangerous heart attack risk factors: diabetes and prediabetes, abdominal obesity, high triglycerides, low HDL cholesterol and high blood pressure.

Affects one in three adults

Affecting about 35 percent of all adults in the United States according to the CDC, metabolic syndrome contributes to weight gain, by causing a state of internal starvation called metabolic starvation. This in turn leads to increases hunger, sugar cravings and increased portions leading to overeating and weight gain.

Cause and effect misunderstood

Since we traditionally thought that the portion control (which in turn was attributed wrongly to poor will power)is the cause of weight gain, rather than the effect of this metabolic starvation, all our traditional ideas about cause and effect of obesity were not only wrong but lead to the “blame the victim” attitude when it comes to obesity.

Secret of weight gain revealed

Secret of weight gain, and metabolic syndrome revealed - it has been recently proven that metabolic syndrome, and the weight gain itself are caused by a process called insulin resistance. Check your metabolic syndrome risk using the free Metabolic syndrome meter. Watch this amazing Ted Med video that reveals the secret of weight loss - Stop blaming the victim for obesity
