Possible side effects of HBOT include the following: Otic barotrauma. This is ear pain or damage to the tympanic membrane caused by rapid changes in pressure, such as when a plane descends to land.
To maintain equal pressure on both sides of the tympanic membrane, gas must move freely between the nasopharynx and middle ear. When the chamber is pressurized, I understand that I must be able to equalize the pressure in my ears to avoid possible severe ear discomfort.
The most effective method to equalize ear pressure is to hold the nose, close the mouth, and blow gently through the nose.
Other methods include yawning, swallowing, and holding the nose while swallowing.
IF THE PRESSURE IN MY EARS FAILS TO EQUALIZE USING ANY OF THESE METHODS, I AGREE TO COMMUNICATE ANY DISCOMFORT TO THE ATTENDANT IMMEDIATELY.
The attendant will adjust the pressure to
attempt to alleviate the discomfort, but if the pressure in my ears cannot be equalized, the treatment will be discontinued promptly. In that event, I understand no further sessions will be scheduled for me until I have obtained a release from my physician for the therapy.
