Part of speech: noun

Definitions

1. Episodes characterized by temporary cessation of breathing during sleep or wakefulness, often leading to disrupted rest and reduced oxygen levels
2. Intervals marked by a pause or absence of breath, typically recurring during sleep and causing intermittent breathing interruptions
3. Periods when breathing stops involuntarily for a short time, commonly associated with sleep disorders and resulting in intermittent hypoxia

Etymology: "Apnoeas" is simply the plural of "apnoea," so the noun itself is the story: it is the form of a term built from two Greek pieces. The first, "a-," is the Greek privative prefix meaning "without" or "not." The second, "-pnoea," comes from Greek "pnoia," meaning "breathing" or "breath," which in turn relates to "pnein," "to breathe" or "to blow." Put together, the literal sense is "without breath." The Greek roots were long established, but the medical term itself is a modern coinage built from them rather than a word the ancient Greeks used for this condition. Its meaning is narrower than "lack of breath" in general: it describes the brief, involuntary pauses in breathing that doctors now study in sleep disorders, where the body briefly stops taking in air and oxygen levels can fall.

Synonyms: apneas, breath-holding, respiratory pauses, cessation of breathing, sleep apnea
