HBOT, Hyperbaric Oxygen Therapy is an additional treatment option that goes along with surgeries, wound care, medication management etc. In Hyperbaric Oxygen Therapy, the patient is made to sit or lie down in an oxygen chamber. The chamber is filled with 100% medical grade oxygen at a pressure of two times or three times that of normal atmospheric pressure.
Normal atmosphere contains only 21% oxygen and that is good enough for normal human body to function well. Filling the chamber with 100% oxygen means that the patient will be breathing 5 times more oxygen and when the pressure is increased, the patient may be taking in 12 times more oxygen than under normal circumstances. As a result, more oxygen gets dissolved in the blood (red blood cells) and also in the plasma part of the blood. Usually, plasma doesn’t carry oxygen in the blood but during HBOT procedure, plasma too carries oxygen to body cells and tissues. This way, more oxygen is supplied to every cell and tissue in the body and that helps in healing wounds or other ailments in the body much faster.
