About this trial
This single-center prospective study enrolls adult patients with long-term tracheostomy who are ready for tube removal (decannulation). Twenty-four hours before decannulation, each participant will receive three physiologic tests-breathing through the tracheostomy tube, breathing with a one-way speaking valve, and breathing with the tube capped. Standard pulmonary-function and arterial-blood-gas measurements will be taken during each test and again 5 days after the tube is removed. The study compares these methods to identify which pre-decannulation test best predicts safe, successful decannulation and to describe the overall impact of tube removal on respiratory function.
Eligibility criteria
Qualifiers
Age ≥ 18 years.
Tracheostomised patient whose primary illness is stable and who is scheduled for elective decannulation in the rehabilitation unit.
Able to tolerate a one-way speaking valve for ≥ 4 h on the day before planned decannulation.
Capable of following instructions and completing bedside spirometry.
Disqualifiers
No tracheostomy in place or requirement for re-intubation/re-cannulation after planned decannulation.
Inability to perform lung-function testing either via the tracheostomy tube or via the mouth/nose (e.g., severe upper-airway obstruction, facial deformity).
Unstable cardiopulmonary or neurological status that makes spirometry unsafe (e.g., ongoing myocardial ischemia, uncontrolled arrhythmia, severe agitation).
Any acute condition requiring isolation precautions that preclude study procedures.
