護理師教導病人使用 MDI 吸入器搭配「儲藥罐(Spacer)」時,應採取哪項行動?
Which action should a nurse take when educating a client about the use of a spacer with an MDI inhaler?
- ATell the client that spacers are unnecessary for medication delivery告訴病人儲藥罐對於給藥並非必要
- BEncourage the client to inhale as rapidly as possible鼓勵病人盡可能快速吸氣
- CAdvise the client to spray the inhaler directly into the throat建議病人將吸入器直接噴入喉嚨
- DInstruct the client to wait 1 minute between puffs✓ 正解指示病人在每次噴射之間等待 1 分鐘

定量噴霧吸入器(MDI)需透過正確技巧確保藥物沉積於肺部。正確使用儲藥罐(Spacer)可減少藥物在口咽部的沉積,並解決病人手眼協調困難的問題。等待 1 分鐘是為了讓藥物氣霧在吸入器內達到穩定狀態,同時讓呼吸道有時間對下一劑藥物產生反應,提高吸收效率。臨床教學應強調緩慢深吸,而非快速吸氣,以避免藥物因氣流過快而撞擊喉嚨。
Waiting one minute between puffs allows the propellant to stabilize and gives the airways time to respond to the previous dose, thereby improving absorption efficiency. This interval ensures optimal medication delivery to the lungs while minimizing side effects.
✦ 台美臨床差異
在美國臨床實務中,對於哮喘或 COPD 病人,使用 Spacer 是標準衛教內容(特別是針對類固醇吸入劑),護理師需確保病人了解其能顯著提升吸入效能及減少局部副作用。
