護理師應指導 COPD 病人採用何種呼吸技巧？
A client with COPD should be taught which of the following breathing techniques?
- ARapid, shallow breathing快速、淺層呼吸
- BDiaphragmatic breathing at all times隨時進行橫膈膜呼吸
- CHyperventilation techniques過度換氣技巧
- DPursed-lip breathing✓ 正解噘嘴呼吸
— Explanation · 中文詳解 —
COPD 病人因肺泡彈性喪失與小氣道塌陷，導致氣體滯留（Air trapping）。噘嘴式呼吸（Pursed-lip breathing）能延長呼氣時間，在呼氣時製造正壓（Positive end-expiratory pressure, PEEP），防止細支氣管過早塌陷，從而將肺內滯留的廢氣排出，改善氧合效率。
Pursed-lip breathing is recommended for clients with COPD because it creates positive end-expiratory pressure (PEEP). This technique helps keep airways open longer, prevents premature collapse, and facilitates the expulsion of trapped air to improve gas exchange.
