Hyperbaric Oxygen Therapy Risks
Like all medical treatments and procedures, some risks are associated with hyperbaric oxygen therapy. These risks are quite rare and they will be discussed with you before you sign your consent form for therapy. During the course of your treatment if you should notice any changes in the way you normally feel let the chamber personnel know.
Monitoring Wound Healing
If you have a non-healing wound, a test may be done to measure the oxygen level in the skin near the wound to see whether the wound is improving. This is called transcutaneous (through the skin) oxygen measurement. A small metal disk is attached to the skin near the wound.
What are the side effects of HBOT?
Middle ear barotrauma . MEB is one of the most common side effects of HBOT. Patients may report difficulty with ear equalization, a feeling of pressure, ear pain, and discomfort during compression, which is the initial phase of HBOT.9.
What is HBOT treatment?
HBOT is the treatment of patients with 100% oxygen at higher than atmospheric pressure.1This is provided in either a monoplace (single person) chamber typically compressed with oxygen or a multiplace chamber (multiple persons) compressed with air where oxygen is delivered by either a hood or mask.
What are the effects of oxidative stress?
Secondary effects as a result of a controlled oxidative stress include antimicrobial effects, blunting of ischemia–reperfusion injury, and wound healing. Wound healing is the result of both local and systemic effects.
Does HBOT help with ulcers?
HBOT has been shown to significantly improve healing rates in certain problem wounds, including advanced diabetic foot ulcers and late effect radiation injury. It is provided in a variety of clinical settings by providers with varying levels of expertise.
Does HBOT increase blood pressure?

What are the three types of cataracts?
Incidence increases over the age of 65. Three types of cataracts have been identified, which are cortical, subcapsular, and nuclear, which is the most common.68They are identified by a yellow-brown discoloration and hazy appearance of the lens in conjunction with the visual changes experienced by the patient.
Is HBOT safe for wounds?
HBOT is an important advanced adjunctive therapy in the treatment of certain problem wounds, primari ly those as a result of late effect radiation injury and diabetes. HBOT remains among the safest therapies used today. The side effects that have been described are self-limiting and often can be avoided with adequate screening.
What is the most common complication of HBO?
Barotrauma is a term that refers to injury due to increased pressure. Barotrauma of the ear is the most frequent complication of HBO. The middle-ear is an air-filled cavity behind the ear drum that connects to the throat through a slit-like passage called the eustachian tube. During compression, if the air pressure in the middle-ear cannot be equalized with the external pressure, the eardrum will bow inward, leading to pain and possibly rupture, leading to hearing loss.
What is decompression sickness?
Decompression sickness, or the bends, is a result of the uptake of nitrogen into the blood when air (which is about 80 percent nitrogen) is breathed at increased ambient pressure. This is generally more of a concern for the inside attendants, who breathe air during a treatment, rather than patients, who are breathing 100% oxygen. This can become a concern if a patient must be removed from oxygen for prolonged periods of time during the dive. Decompression sickness can result in pain, neurological injury, cardiopulmonary collapse, and possibly death.
What causes a drop in the lung?
Pulmonary barotruama refers to damage to the lung tissue as a result of pressure change, resulting in air leaking from the lungs into the chest cavity causing a dropped lung, or pneumothroax. This generally occurs in patients with air trapping lesions in the lungs, such as can occur in emphysema or asthma. During decompression, these air-filled pockets will begin to expand, and, if the pressure is not relieved by the airways in the lungs, these pockets can rupture. This released air can cause excess pressure in the chest cavity leading to difficulty breathing and decreased blood pressure that can result in death if untreated. Treatment consists of emergency evacuation of air from the chest cavity by inserting a needle through the chest wall, and, subsequently, placing a chest tube to re-expand the lung.
Can diabetes cause blood sugar to drop?
Hypoglycemia. Some patients with diabetes experience a drop in blood sugar during hyperbaric treatments. In order to prevent this, patients are encouraged to eat before coming for treatments and blood glucose is monitored during the dive at appropriate intervals.
Is hyperbaric oxygen therapy safe?
While it's generally very safe, as with all medical treatments, Hyperbar ic Oxygen Therapy carries with it the risk of complications that in rare instances can be life threatening and/or result in permanent or long-term disability.
Can hyperbaric therapy cause seizure?
The high level of oxygen in the blood that occurs during HBO treatments can be toxic to the central nervous system and can result in seizure activity. While this is rare during clinical hyperbaric treatments, it does occur and may be more likely in those with pre-existing seizure disorders or hypoglycemia (low blood sugar). Treatment consists of simply removing the supplemental oxygen from the patient, which will terminate the seizure.
Can elevated oxygen levels cause respiratory failure?
Elevated oxygen concentrations can be detrimental to the lungs. Prolonged exposure to high levels of oxygen can eventually lead to chest pain, difficulty breathing, and eventually, respiratory failure. In the early stages of the condition, the lungs rapidly return to baseline once the oxygen concentration is decreased. Thus, due to the intermittent nature of HBO treatments, pulmonary oxygen toxicity is rarely seen in clinical practice. On the other hand, this can become a concern in critically ill patients who must be maintained on supplemental oxygen between treatments or those patients who require unusually frequent or prolonged treatment courses.

What is HBO2 therapy?
Hyperbaric oxygen therapy is used in the management of serious infections, like diabetic foot infections, fugal infections, neurosurgical infections, gangrene and necrotizing fascilitis (also known as flesh-eating disease). HBO2 therapy acts as an antibacterial agent by increasing the formation of free oxygen radicals.
Why is oxygen important?

What is HBOT in medical terms?
Hyperbaric oxygen therapy (HBOT) involves supplying the body’s blood and tissues with pure oxygen in order to promote healing. Hyperbaric medicine was first used in the 1600s when patients went into airtight chambers that could be compressed and decompressed.
How does HBO2 work?
It works to restore the bacteria-killing abilities of white blood cells in wounds by increasing tissue oxygen tensions, and studies show that it even works synergistically with a number of antibiotics. 3. Heals Chronic Wounds.

What is decompression sickness?
