## 題目

新診斷中度OSA病人開始居家CPAP。哪句話顯示需進一步衛教?

## 選項

1. 我每晚睡眠期間都會使用CPAP
2. 減5磅後我就能停CPAP,因為呼吸中止會痊癒 **✔ 正確答案**
3. 依製造商指示定期清潔面罩與加濕器水箱
4. 若鼻乾或皮膚受損會回診睡眠門診

**正確答案: 2**

## 解析

減重可降低OSA嚴重度,但無法治癒中度OSA;須持續CPAP直到複檢多項睡眠檢查確認消失。順從性定義為70%夜晚使用超過4小時,目標是整段睡眠期間使用(無呼吸多在REM晚期)。面罩衛生與副作用追蹤正確。

## 深入解析

常見誤解:小幅減重即可消除OSA。停CPAP需重做多項睡眠檢查。未治療OSA增加心血管死亡率、高血壓與心房顫動。

## 臨床情境

AHI 22次/小時。BMI 34。日間嗜睡與配偶目擊呼吸中止。出院使用自動調壓CPAP與鼻型面罩。

## 重要概念

- **阻塞型睡眠呼吸中止症** — 睡眠中上呼吸道反覆塌陷,造成呼吸中止與低通氣。
- **AHI** — 呼吸中止低通氣指數,每小時事件數。5-14輕度、15-29中度、30以上重度。
- **CPAP** — 持續性正壓呼吸 — 上呼吸道氣動支撐。
