Which condition results from a pressure-related injury?

• A. Drowning
• B. Barotrauma
• C. Altitude Sickness
• D. Near-Drowning

Answer: (B)

Barotrauma is the injury that happens when rapid changes in ambient pressure cause a mismatch with the pressure inside air-filled spaces in the body. When you’re in situations like diving, flying, or any scenario with changing pressure, gases in the ears, sinuses, or lungs need to be able to equalize with the surrounding pressure. If they can’t, the pressure difference can stretch or rupture membranes—think a painful eardrum, sinus pain, or even lung overexpansion injuries.

That’s why this option fits best: it’s the classic pressure-related injury, arising specifically from the body’s inability to equalize pressure during changes in ambient pressure. Drowning and near-drowning involve submersion and water inhalation rather than injury from pressure changes, and altitude sickness stems from reduced oxygen availability at higher pressures, not from tissue injury due to pressure differences.
