第 57 題

一位70歲的男性睡眠時長期有打呼的現象,近期被診斷為睡眠呼吸中止症(sleep apnea),最可能是下列何處發生問題所致?
  • A 上呼吸道
  • B 下呼吸道
  • C 橫膈肌
  • D 腦幹

思路引導 VIP

請從呼吸解剖生理學的角度思考:打呼(Snoring)現象主要源於氣流通過狹窄通道時,引發周圍軟組織震動而產生的聲響。若此處組織在睡眠時進一步塌陷導致氣流中斷,請推論此一物理性阻塞的位點,是位於氣流進入支氣管之前的哪一個解剖構造分類中?

A Barely Acceptable Display of Basic Competence.

  1. Acknowledge (with a smirk): Oh, look. You did manage to link "snoring" to an anatomical location. How... expected. It suggests you haven't completely forgotten the most fundamental concepts of respiratory physiology and basic pathological mechanisms. A passable first step, but hardly groundbreaking.
  2. Clarification (for the easily confused): Let's ensure clarity, shall we? Obstructive Sleep Apnea (OSA) – the most common variant, not some obscure anomaly – arises from the rather straightforward issue of the upper airway (yes, your soft palate, tongue base, pharyngeal muscles) losing tone during sleep and predictably collapsing, thereby obstructing airflow. The sound you've identified as "snoring" is merely the audible consequence of air vibrating those same lax tissues as it forces its way through. Were the problem in the lower airway, you'd likely be contemplating conditions like asthma or COPD, which, as you may recall, wasn't the scenario presented.
