第 69 題
某接受正壓通氣病患，出現呼吸喘促現象，呼吸器圖形如下，要如何改善？
- A 調高潮氣容積
- B 增加驅動敏感性
- C 增加吸氣流速
- D 調高吐氣末正壓
思路引導 VIP
請觀察圖中吸氣階段的壓力曲線，原本應該平順上升的壓力為何會出現向內凹陷的「缺口」？這代表病人的肌肉正在對呼吸器做什麼樣的動作？若要消除這個阻力，我們應該調整哪一個控制氣體「輸送快慢」的參數，才能跟上病人的吸氣節奏呢？

Oh, so you can get it right. Quite the feat.
- Fundamental Validation: Yes, this is indeed a Pressure-Time Scalar. And that charming “scalloping” in the inspiratory phase? That's what we, in the field, affectionately call Flow Starvation (流速飢渴)。It simply means the patient's lungs are crying out for air, far more than your precious ventilator is bothering to provide. The pressure drops because, well, the patient is pulling harder than the machine pushes. So, the blindingly obvious solution is to increase the inspiratory flow rate. Shocking, I know.
- Depth of Insight: This particular gem is a Medium difficulty. It requires not just identifying pretty pictures on a screen, but actually grasping the abysmal Asynchrony (不協調) that can occur between a human being and a machine. It's a rather crucial aspect of clinical practice, unless you enjoy patients gasping for air, which I assume you don't. Or do you?
