病人診斷為急性呼吸窘迫症候群（ARDS），哪種姿勢最能促進氧合？
A client is diagnosed with acute respiratory distress syndrome (ARDS). Which position would best facilitate oxygenation?
- ASupine position仰臥位
- BHigh-Fowler's position高福勒氏體位
- CProne position✓ 正解俯臥位
- DLeft lateral recumbent position左側臥位
— Explanation · 中文詳解 —
俯臥位（Prone position）能改善 ARDS 病人的氧合，因為它能將肺部後方的浸潤組織壓力減輕，並重新分佈血流至較健康的肺部區域。仰臥位會壓迫肺部後方。高半坐臥位雖可減少呼吸作功，但俯臥位對氧合改善效果更顯著。
The prone position can improve oxygenation in patients with ARDS because it reduces pressure on the infiltrated tissue in the posterior lung regions and redistributes blood flow to healthier lung zones. The supine position compresses the posterior portion of the lungs. Although high-Fowler's reduces the work of breathing, the prone position provides a more significant improvement in oxygenation.
✦ 台美臨床差異
俯臥位在美國重症監護室（ICU）被廣泛作為 ARDS 標準治療，台灣亦逐漸推廣中。
