hypopnea 指“低通气”:睡眠或呼吸过程中,气流/通气量明显减少的一种呼吸事件,常见于睡眠呼吸障碍(如阻塞性睡眠呼吸暂停相关疾病)。在临床睡眠监测中,低通气通常按“气流下降达到一定幅度并持续一定时间,且伴随血氧下降或觉醒”等标准来判定。(该词也可在更广义上指通气不足,但最常见用法与睡眠医学相关。)
/haɪˈpɒpniə/
The sleep test showed several hypopnea events.
睡眠检测显示出现了多次低通气事件。
Although he didn’t stop breathing completely, repeated hypopnea during the night still lowered his oxygen levels and made him tired during the day.
尽管他没有完全停止呼吸,但夜间反复的低通气仍然降低了血氧水平,并导致他白天疲劳。
来自现代医学构词:hypo-(“低、少、不足”,源自希腊语 hypo)+ -pnea(“呼吸”,源自希腊语 pnoē,意为“呼吸/气息”)。合起来就是“呼吸减少”的意思。
