barotrauma
C2Technical/Medical
Definition
Meaning
Injury caused to body tissues by changes in ambient pressure, typically affecting air-filled spaces like ears, sinuses, or lungs.
Any physical damage resulting from pressure differences between a gas inside a body cavity and the surrounding environment, commonly experienced during diving, flying, or medical ventilation.
Linguistics
Semantic Notes
A compound noun from Greek roots; always refers to pressure-related injury. Not to be confused with trauma from blunt force alone.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. Spelling is identical.
Connotations
Technical/medical term in both varieties; no additional connotations.
Frequency
Equally rare in general discourse; slightly more frequent in American English due to larger scuba-diving and aviation communities.

Examples
By Part of Speech
verb
British English
- The diver was barotraumatised during the rapid ascent.
- The pilot reported barotraumatising his sinuses.
American English
- The patient was barotraumatized by the ventilator settings.
- He barotraumatized his ear on the flight.
adverb
British English
- The eardrum ruptured barotraumatally.
adjective
British English
- The barotrauma injury was significant.
- Barotrauma risk increases with depth.
American English
- The barotrauma risk is assessed pre-flight.
- She had a barotrauma-related hearing loss.
Examples
By CEFR Level
- The flight made my ears hurt.
- A sudden change in air pressure can hurt your ears.
- Divers must ascend slowly to avoid pressure-related injuries to their ears and lungs.
- Pulmonary barotrauma is a serious risk for divers who hold their breath during ascent.
Learning
Memory Aids
Mnemonic
BARO (like barometer, measures pressure) + TRAUMA (injury) = injury from pressure change.
Conceptual Metaphor
PRESSURE IS A FORCE (that can injure); THE BODY IS A CONTAINER (with air spaces vulnerable to pressure changes).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as "баротравма" (a direct calque); the correct medical term is "баротравма", but the concept may be described as "баротравма" in technical contexts, though less common in general speech.
Common Mistakes
- Pronouncing it as /ˈbærəʊtrɔːmə/ (incorrect primary stress on first syllable).
- Confusing it with 'trauma' from impact.
- Using it for pressure damage to inanimate objects (reserved for living tissue).

FAQ
Frequently Asked Questions
No. Barotrauma is direct tissue damage from pressure imbalance. 'The bends' (decompression sickness) is caused by dissolved gases forming bubbles in the bloodstream.
Yes, forcibly holding your nose and mouth closed during a sneeze can cause a sudden pressure increase in the middle ear or sinuses, potentially leading to barotrauma.
Mild forms like ear 'popping' or discomfort during flight are common. Serious barotrauma requiring medical attention is relatively rare in the general population but is a known occupational hazard for divers and aviators.
Middle ear barotrauma (otic barotrauma), often called 'ear squeeze', is the most frequently experienced form, particularly during air travel or scuba diving.
