hyperbaric chamber
C1Technical/Medical
Definition
Meaning
A sealed, pressurised vessel in which patients breathe pure oxygen, used for medical treatment.
Any pressurised enclosure designed to sustain higher-than-atmospheric pressure, used in medical therapy, research, or diving simulation.
Linguistics
Semantic Notes
The term is a compound noun. 'Hyperbaric' refers to high pressure, while 'chamber' denotes an enclosed space. It is almost exclusively used in medical and diving contexts.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences; minor spelling variations in related documentation (e.g., 'pressurised' vs. 'pressurized').
Connotations
Identical technical connotations in both dialects.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation of 'chamber' as 'камера' in a legal/prison context. The correct technical term is 'барокамера'.
- Do not confuse with 'hyperbolic' (гиперболический), which is mathematical.
Common Mistakes
- Incorrect spelling: 'hyperbarric chamber', 'hyperbaric chamer'.
- Incorrect article: 'an hyperbaric chamber' (should be 'a hyperbaric chamber').
- Misunderstanding: Thinking it is for hypothermia (low temperature) rather than high pressure.

Frequently Asked Questions
They are similar in technology, but a decompression chamber is used primarily to prevent or treat decompression sickness in divers, while a hyperbaric chamber is a broader term for medical oxygen therapy under pressure.
Common treatments include decompression sickness ('the bends'), carbon monoxide poisoning, severe infections like necrotising fasciitis, non-healing wounds (e.g., diabetic foot ulcers), and radiation tissue damage.
Yes, similar to the sensation in an aeroplane during ascent or descent, you may feel pressure in your ears, which can be relieved by yawning or swallowing.
A session typically lasts between 60 to 120 minutes, depending on the medical condition being treated. A full course of treatment may involve multiple sessions over several days or weeks.
