[呼吸治療師] 呼吸治療儀器設備學
第 68 題
下列何種肺部擴張治療是以正壓呼吸作用於吸氣期?①間歇正壓呼吸(IPPB) ②連續呼吸道正壓(CPAP) ③吐氣正壓(positive expiratory pressure,PEP) ④誘發性肺量計法(incentive spirometry)
- A 僅①
- B 僅①④
- C 僅①②④
- D ①②③④
思路引導 VIP
請試著從「壓力的方向」來思考:如果我們希望在患者吸氣的瞬間,由外部設備提供一個「推力」來幫助肺部撐開,而非讓患者辛苦地自己吸氣,那麼這個設備必須在呼吸週期的哪一個階段,提供高於大氣壓力的能量?

Hmph. Not a speck of dust.
- You got it right, 小鬼. No unnecessary errors here. This confirms you grasp the basic mechanics of Lung Expansion Therapy—a critical understanding if you're not going to make a mess of things later.
- Listen carefully: IPPB is when the machine provides positive pressure during inspiration, after the patient triggers it. It's a calculated intervention to boost transpulmonary pressure ($P_{tp} = P_{aw} - P_{pl}$), nothing more.
