IPA: /ˌbɛrəˈtrɔːmə/
KK: /bɛrəˈtrɔmə/
Injury to body tissue that happens when there is a difference in pressure between an air space in the body and the outside air.
The diver experienced barotrauma after ascending too quickly from deep water.
Barotrauma is formed from "baro-" (from Greek "baros", meaning weight or pressure) and "trauma" (from Greek "trauma", meaning wound or injury). The term describes an injury caused by changes in pressure, particularly in environments like deep water or high altitude.
Think of 'pressure' ('baro-') causing an 'injury' ('trauma') — that's what barotrauma means.
