When can the artificial airway be removed?
Finally, let’s discuss when an artificial airway can be removed. An artificial airway is established as a substitute therapy when a patient is unable to adequately protect their own airway.

Therefore, removal of the artificial airway requires fulfillment of two critical conditions:
1. The patient’s level of consciousness and functional capacity must be sufficient to ensure adequate self-protection of the airway.

2. Additionally, upper airway (i.e., “gate”) function must be well preserved. In some cases, upper airway function may not yet be fully restored; however, if the patient demonstrates excellent mental status, strong coughing ability, relatively clean airways, absence of significant inflammation, and no gastroesophageal or nasogastric tube feeding-related reflux, removal of the artificial airway may still be considered—followed by continued swallowing rehabilitation to further reduce aspiration risk.

If neither of the above criteria is met and the artificial airway is prematurely removed, recurrent pulmonary infection may occur within days, causing considerable distress to the patient. Therefore, removal of an artificial airway must always be performed only after thorough evaluation by qualified healthcare professionals. In home care settings, if caregivers observe airway cuff deflation, difficulty advancing the suction catheter, or other concerning signs, prompt medical consultation is essential to identify the underlying cause—and, if necessary, replace the artificial airway—to ensure patient safety.
