Which factor is crucial while descending to avoid injury during equalization?

Monitoring ear pressure during descent is essential for preventing injury because it helps divers recognize when they need to equalize the pressure within their ears and avoid barotrauma. As a diver descends, the pressure increases, causing the air in the middle ear to become compressed. To equalize this pressure, divers typically perform techniques such as the Valsalva maneuver or the Frenzel maneuver. By actively monitoring ear pressure, divers can proactively equalize at appropriate intervals, ensuring they do not experience discomfort or damage to their eardrums or surrounding structures.

Rapid or forceful attempts to equalize, such as breathing quickly or pushing hard against the pressure, can lead to injury rather than alleviating it. Furthermore, avoiding equalization altogether risks serious complications. Therefore, understanding and monitoring ear pressure is key to safe diving practices.
