一位有睡眠呼吸中止症病史的病人，在睡眠期間出現哪些評估發現需要護理介入？
Which assessment finding in a client with a history of sleep apnea indicates a need for nursing intervention during sleep?
- AFrequent waking with a gasp頻繁驚醒並伴隨喘息
- BOxygen saturation dropping to 85% during apneic episodes✓ 正解呼吸中止期間血氧飽和度降至 85%
- CRestlessness during REM sleep快速眼動睡眠期間躁動不安
- DSnoring occurring throughout the night整夜持續打呼
睡眠呼吸中止症（sleep apnea）病人常有打呼與睡眠中驚醒的症狀，這主要與氣道阻塞導致的間歇性缺氧有關。在所有選項中，血氧濃度（SpO2）下降至 85% 是嚴重的生理性損害指標，代表組織氧合不足，這會增加心臟負荷與心律不整風險，屬於必須立即介入的臨床危急狀況。打呼與驚醒雖是診斷徵象，但血氧過低直接威脅病人生命安全，優先級最高。
Clients with sleep apnea often experience snoring and waking from sleep, primarily related to intermittent hypoxia caused by airway obstruction. Among all options, a drop in oxygen saturation (SpO2) to 85% is a significant indicator of physiological compromise, representing inadequate tissue oxygenation. This increases cardiac workload and the risk of arrhythmias, and is a critical clinical situation that must be addressed immediately. Although snoring and arousals are diagnostic signs, hypoxemia directly threatens the client's life and is therefore the highest priority.
