Jul 14, 2023 · People with obstructive sleep apnea repeatedly stop and start breathing while they sleep. There are several types of sleep apnea. Obstructive sleep apnea occurs when the throat muscles relax and block the airway. This happens off and on many times during sleep. A sign of obstructive sleep apnea is snoring.

Nov 15, 2022 · Obstructive sleep apnea (OSA) is when a blockage in your airway keeps air from moving through your windpipe while you’re asleep. The blockage and lack of airflow can cause your blood oxygen levels to drop, triggering a survival reflex in your brain that wakes you up just enough to breathe again.

睡眠呼吸中止症 （英語： sleep apnea 或 sleep apnoea ，又譯作 睡眠呼吸中止症 或 睡眠窒息症 ）是一種在 睡眠 期間， 暫停呼吸 或 呼吸減弱 症狀導致的 睡眠紊亂 。 每一次的暫停期間可從數秒鐘到數分鐘不等，而且整晚發生好幾次 [1] 。 在一般情況下，這個症狀會產生吵雜的 打鼾 聲 [2] 。 當重新呼吸時，有時會有窒息或鼻音等的聲音出現。 當此症狀破壞正常睡眠時，會造成白天的嗜睡或感到疲累的現象 [1] 。 對於兒童，會產生在學校的狀況問題或 注意力不足過動症 （特別是ADHD的過動症狀） [2] 。
美国光学学会（The Optical Society of America，OSA ），成立于 1916 年，是光学领域权威的国际性学术组织。. OSA 的宗旨是促进光学和光子学知识的发展、应用和保存，并将这些知识传播到全世界。. 除了光学和光子学领域，还为物理学、生物学、医学、电气工程、通讯 ...
阻塞性睡眠呼吸暂停(obstructive sleep apnea, OSA)的特征是睡眠过程中上气道反复塌陷导致的阻塞性呼吸暂停和低通气。 未经治疗的OSA可能导致多种后果，包括日间过度思睡、日间功能受损、代谢功能障碍及心血管疾病和死亡风险增加。
