Diver clearing ears Section of the human ear, the Eustachian tube is shown in colour. Ear clearing, clearing the ears or equalization is any of various maneuvers to equalize the pressure in the middle ear with the outside pressure, by letting air enter along the Eustachian tubes, as this does not always happen automatically when the pressure in the middle ear is lower than the outside pressure.
Equalization becomes difficult, if not impossible, when we are agitated. When we aren't feeling well during a dive, we tend to stiffen up. Equalization suffers tremendously when you're not ready or prepared for the dive, can't relax throughout the descent, have early contractions, or are fatigued, anxious, or stressed.
Variations of the maneuver can be used either in medical examination as a test of cardiac function and autonomic nervous control of the heart (because the maneuver raises the pressure in the lungs), or to clear the ears and sinuses (that is, to equalize pressure between them) when ambient pressure changes, as in scuba diving, hyperbaric oxygen ...
This helps because swallowing or moving the jaw can help equalize the pressure and prevent it from becoming uncomfortable from the built-up pressure in the Eustachian tube. ... to take an over-the ...

Middle ear barotrauma (MEBT), also known to underwater divers as ear squeeze and reverse ear squeeze, is an injury caused by a difference in pressure between the external ear canal and the middle ear. It is common in underwater divers and usually occurs when the diver does not equalise sufficiently during descent or, less commonly, on ascent.
You hear it from every corner of the earth when you’re a woman of a certain age. “Lift heavy,” say the experts. “Cardio adds years to your life, but weightlifting adds life to your years.”
These are surface oriented dives, where the diver starts and ends the dive at atmospheric pressure, and saturation dives, where the diver remains under pressure close to that of the working depth before, during, and after the underwater dive exposure, and is compressed before a series of dives, and decompressed at the end of the series of dives.
