The term “hyperbaric” pertains to involvement of a gas at a pressure greater than normal and this is one technique that has therapeutic objective. You might have heard of hyperbaric medicine, a kind of medicinal treatment. It also involves use of oxygen gas at high pressure and is also referred to as hyperbaric oxygen therapy (HBOT). This is well-known therapy for decompression sickness, a hazard relating to scuba diving which is a swimming underwater sport of old times. This treatment is useful in many other conditions that include unhealed wounds due to radiation injury or diabetes, serious infections, air bubbles in blood vessels, and many others.
How this treatment is performed
In hyperbaric therapy, air pressure three times greater than normal pressure is created in hyperbaric oxygen chamber and a patient can breathe pure oxygen in this pressurized room or through a tube. This breathed oxygen is circulated in the whole body through blood and helps to fight bacteria and promotes healing. Release of substances like stem cells and growth factors is also stimulated in this process.
Mechanism of HBOT working
The mechanism of action of hyperbaric treatment is simple and based on biological principle that tissues need sufficient supply of oxygen for efficient functioning. When a tissue is damaged, more supply of oxygen is needed to restore it which is not possible with normal oxygen supply. HBOT increases this supply so that tissue is nourished more. Oxygen is supplied to all cells, tissues, and organs through blood circulation and HBOT increases the amount of oxygen in the blood. As a layman, one can easily understand this theory that a patient requires more nutrients to get well soon. Tissue is a vital part of human body and needs same kind of treatment for quick healing. This is very effective therapy that is used by hospitals and medical institutions to treat large number of health conditions.
