barostat
Rare/Very low frequencyTechnical/Scientific
Definition
Meaning
A device that automatically regulates or maintains constant pressure.
A physiological mechanism or medical device that maintains constant pressure in a biological system; in medicine, often refers to a gastric barostat used to measure stomach tone and sensitivity.
Linguistics
Semantic Notes
Primarily used in medical, physiological, and engineering contexts; often denotes both a mechanical device and the biological reflex systems that maintain pressure homeostasis.

Examples
By Part of Speech
verb
British English
- The system was barostatted to maintain 12 mmHg.
- Researchers barostatted the gastric balloon.
American English
- The apparatus was barostatted at 10 mmHg.
- They barostatted the colon segment.
adverb
British English
- The pressure was maintained barostatically.
- The device functioned barostatically.
American English
- The system operated barostatically.
- Measurements were taken barostatically.
adjective
British English
- The barostat-controlled environment remained stable.
- We used a barostat methodology.
American English

Examples
By CEFR Level
- A barostat is a device that keeps pressure constant.
- Doctors sometimes use a barostat to check stomach function.
- The gastric barostat is a key tool for assessing visceral hypersensitivity in functional gastrointestinal disorders.
- The study employed an electronic barostat to isobarically distend the rectal wall and measure compliance.
Learning
Memory Aids
Mnemonic
Think of 'baro-' (pressure, like barometer) + '-stat' (stationary/constant device, like thermostat). A barostat keeps pressure static.
Conceptual Metaphor
A PRESSURE THERMOSTAT (maintaining a set pressure like a thermostat maintains temperature).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'барометр' (barometer), which measures but does not regulate pressure.
- Avoid translating as 'регулятор' without specifying it's for pressure; in Russian medical texts it's often 'баростат' or 'гастральный баростат'.
Common Mistakes
- Misspelling as 'barostate' or 'barostator'.
- Confusing with 'barometer' (measurement vs. regulation).
- Using in non-technical contexts where 'pressure regulator' would be clearer.

FAQ
Frequently Asked Questions
No, it is a highly specialized technical term used almost exclusively in medical and physiological contexts.
A barometer measures atmospheric pressure, while a barostat actively regulates and maintains a set pressure in a closed system.
In highly technical writing, it can be used verbally (e.g., 'to barostat a system'), but this is very rare and not standard in general English.
In general engineering, 'pressure regulator' is a common synonym, but in medicine, 'gastric barostat' is a specific device with no perfect synonym.
