hypopnea
C2Technical/Medical
Definition
Meaning
Abnormally shallow or slow breathing.
A clinical term for a sleep-related breathing disorder where airflow is reduced by a certain percentage, causing oxygen desaturation or arousal from sleep. It is a milder form of breathing difficulty than apnea.
Linguistics
Semantic Notes
A countable noun in clinical contexts (e.g., 'several hypopneas'). Primarily used in sleep medicine, pulmonology, and neurology. Denotes a measurable event in polysomnography.
Dialectal Variation
British vs American Usage
Differences
No significant spelling or definition differences. Pronunciation differs (see IPA).
Connotations
Purely clinical in both varieties.
Frequency
Exclusively used in medical/technical contexts in both regions; laypersons are unlikely to know the term.

Used in medical and life sciences research papers, particularly on sleep disorders.
Everyday
Virtually never used outside a medical consultation regarding sleep issues.
Technical
The primary context. Used in sleep studies, CPAP machine specifications, clinical diagnoses, and medical journals.
Examples
By Part of Speech
adjective
British English
- The hypopneic events were recorded.
- The patient showed a hypopneic breathing pattern.
American English
- The hypopneic episodes were frequent.
- A hypopneic response was observed.
Examples
By CEFR Level
- The doctor said his poor sleep might be due to shallow breathing at night.
- Sleep apnea is well-known, but its milder form, hypopnea, is also a serious sleep disorder.
- The polysomnogram revealed an apnea-hypopnea index of 15 events per hour, indicating moderate sleep-disordered breathing.
- Central hypopnea, characterized by diminished respiratory drive, must be distinguished from its obstructive counterpart in the diagnostic evaluation.
Learning
Memory Aids
Mnemonic
Think: 'HYPO-' (low/under) + '-PNEA' (breathing) = low/under-breathing. Like its opposite 'hyperpnea' (over-breathing).
Conceptual Metaphor
Breathing as a measurable volume; a 'dip' or 'lull' in the wave of respiration.

Common Pitfalls
Translation Traps (for Russian speakers)
- Не путать с 'апноэ' (полная остановка дыхания).
- Не является общеупотребительным словом; в бытовом языке чаще скажут 'неглубокое дыхание' или 'слабые вдохи'.
Common Mistakes
- Misspelling as 'hypopnoea' (Brit.) / 'hypopnia' (common error).
- Confusing it with 'apnea' (cessation of breathing).
- Using it as a verb (e.g., 'he hypopneas').

FAQ
Frequently Asked Questions
Apnea is a complete or near-complete cessation of airflow for ≥10 seconds. Hypopnea is a significant reduction (typically 30-90%) in airflow for ≥10 seconds, often accompanied by oxygen desaturation or arousal from sleep.
Yes, chronic hypopnea can lead to fragmented sleep, daytime sleepiness, cardiovascular strain, and is a component of Sleep Disordered Breathing, which requires medical evaluation.
Yes, treatment options similar to sleep apnea include CPAP therapy, oral appliances, positional therapy, and weight management, depending on the underlying cause.
It is diagnosed via an overnight sleep study (polysomnography) which measures airflow, breathing effort, blood oxygen levels, and brain activity.
