瞭解氣管造口管：醫療專業人員必備指南 (Understanding Tracheostomy Tubes: Essential Guide for Medical Professionals)

- And that's important to know because air flows through the fenestration when there's a hole, and obviously air doesn't flow through if there's no hole, meaning that with this tracheostomy, air can only go in and out and it won't go up past the vocal cords and through the patient's mouth when they exhale if there's no fenestration.
這一點很重要，因為如果有孔，空氣就會流經柵欄，如果沒有孔，空氣顯然就不會流經柵欄，也就是說，如果沒有柵欄，氣管造口術後，空氣只能進不能出，呼氣時也不會經過聲帶和病人的口腔。
- So for example, in this trach, if I put this inner cannula in and it doesn't have a fenestration, then I'm still completely controlling the airflow through the airway and none of it is escaping through the back of the fenestration of the trach because there's no fenestration in the inner cannula.
例如，在這個氣管中，如果我將這個內套管放進去，但它沒有柵欄，那麼我仍然可以完全控制氣道中的氣流，沒有任何氣流會從氣管柵欄的後面漏出，因為內套管中沒有柵欄。
