What are hyperbaric oxygen treatments like?
Hyperbaric oxygen treatments include three phases: compression to the prescribed treatment pressure, the prescribed time at pressure, and decompression from the treatment pressure back to surface or atmospheric pressure. Compression: During the compression phase patients feel a “fullness” in their ears similar to what is experienced as a commercial airliner lands. This increase in pressure on the tympanic membrane or ear drum must be equalized by performing a valsalva maneuver or be swallowing or yawning. The temperature in the chamber also increases slightly during compression. Treatment: The treatment phase begins when the pressure reaches the prescribed level. The patient breathes 100 per cent oxygen with brief interruptions to breath air to reduce the risk of any toxic reaction to prolonged oxygen breathing. During the treatment patients may rest, sleep, listen to music, or watch television. Decompression: During decompression the pressure within the chamber is reduced to that at t
