How does a session work?
Indoors, the user normally breathes the pressurised oxygen absorbed through the lungs into the bloodstream and transported through the body by the circulatory system. In this way, the user receives 15 times the amount of oxygen compared to breathing air at sea level. The treatment is administered while the user is lying down in the hyperbaric chamber. For the first 5 minutes, you will feel the pressure change in your ears (much like when you are descending in an aeroplane). An assistant will guide you during the first few sessions to help you relieve this sensation of "plugged" ears. When you reach the indicated pressure, you will hear air escaping through the pressure regulating valve (1.3ATA) and you will no longer have discomfort in your ears. Once the therapy starts, you put on the nasal goggles or the oxygen mask and can relax by breathing in the pure oxygen. In the meantime, you can listen to music, watch a movie, read or chat, rest or sleep until the session is over. Each treatment lasts approximately 60 minutes. At the end of the treatment, the pressure will gradually decrease in the chamber (decompression). During decompression, you may experience a "crackling" sensation in your ears as a result of the pressure change. This is a normal adjustment for your ears (much like the sensation when reaching altitude in an aeroplane).
If for any reason you want to leave before the end of the session, the hyperbaric chamber has an emergency valve that reduces the pressure in 30 seconds. The zip can never be opened before returning to 0 kilopascal.
