Официальное название
Study on the Impact of Tracheostomy Decannulation on Pulmonary Function in Adult Patients
Обзор
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.
Вмешательства
- Устройство Speaking Valve ,Tracheostomy Tube Occlusion ,Tracheostomy Tube Ventilation
Speaking Valve: Participants are assessed while breathing through a one-way speaking valve attached to the tracheostomy tube. The valve directs exhaled air through the upper airway, restoring phonation and more closely simulating post-decannulation airflow. The assessment is performed for up to 4 hours to evaluate tolerance and respiratory function prior to tracheostomy tube removal. Tracheostomy Tube Occlusion: Participants undergo a capping trial, in which the tracheostomy tube is completel

Критерии участия
Критерии включения
- 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.
- Patient (or legally authorised representative) has provided written informed consent.
Критерии исключения
- 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.
- Refusal or inability to sign informed consent.
- Missing or incomplete key outcome data.
