What Does HBOT Feel Like?
Once you are in the hyperbaric chamber, the nurse or technician shuts the door but remains visible through the glass. You can also talk by phone.
Initially, you will hear the oxygen begin to circulate in the chamber. As the pressure gradually increases (compression), you may feel temporary warmth. Your ears may feel "full," similar to traveling down a mountain or flying in an airplane. The nurse or technician coaches you on clearing your ears.
It only takes about 10 minutes to reach the prescribed pressure. The fullness in the ears ceases and you can rest comfortably, sleep, watch TV, or listen to music for 1-2 hours.
Near the end of treatment, the pressure is gradually decreased (decompression). A slight "popping" in the ears is normal.
