What Will I Feel During a Hyperbaric Oxygen Treatment?

The treatment is provided while you lay down on a bed and then placed inside the hyperbaric chamber.

Once the treatment starts (compression), you will hear the oxygen begin to circulate in the chamber. You will feel the change in pressure in your ears (similar to the feeling of driving down a mountain road or descending in an airplane).  A nurse will coach you during the first few treatments to help you to relieve this “full” sensation in your ears.  

When you reach the prescribed pressure, you will no longer need to clear your ears.  You may listen to music, watch TV or a movie, rest, or sleep for the remainder of the treatment.

Each treatment lasts about 90 to 120 minutes.  Near the end of the treatment, the nurse will gradually decrease the pressure in the chamber (decompression).  During decompression, you may experience a “popping” sensation in your ears as a result of the changing pressure.  This is a normal adjustment in your ears (similar to the feeling of driving up a mountain road or gaining altitude in an airplane).
