In many of the larger capacity hyperbaric chambers, the patients and treatment staff inside the hyperbaric chamber will normally breathe 100% pure oxygen through either a face oxygen mask or an oxygen hood. Some oxygen masks are designed to take the exhaust gas that the patients breathe out outside the chamber. The oxygen masks are normally attached to an exhaust gas manifold inside the chamber that allows the exhaust gas to be extracted outside of the hyperbaric chamber.
Throughout the hyperbaric treatment, patients inside the hyperbaric chamber breathe 100% pure oxygen in order to maximise the effectiveness of the hyperbaric treatment. They do have regular “air breaks” so as to minimise the risk of oxygen toxicity. Breathing pure oxygen for prolonged periods at elevated partial pressure can be poisonous to the human body and result in cell damage and death, with effects most often seen in the central nervous system, lungs and eyes.
The exhaled gas must be removed from the chamber to prevent the build up of oxygen which can prevent a serious fire risk. Treatment staff inside the chamber will also breathe pure oxygen to reduce their risk of decompression sickness. The hyperbaric chamber pressure is increased by opening valves allowing high pressure air to enter from storage cylinders, which are filled by an air compressor.
