What is the primary concern when experiencing barotrauma?

The primary concern when experiencing barotrauma is pressure-related injury. Barotrauma occurs when there is a difference in pressure between the outside environment and the air-filled spaces in the body, which can cause injury to those spaces. Commonly affected areas include the lungs, ears, and sinuses. When a diver ascends or descends rapidly without equalizing this pressure, it can lead to tissue damage, bleeding, or other serious complications in these areas.

Addressing barotrauma promptly is crucial since it can lead to more severe conditions such as pneumothorax or other life-threatening injuries if the pressure differences are not corrected. Understanding this concept is vital for divers to mitigate risks and follow proper equalization techniques during descents and ascents.
