SV With TTPEE Measurement Predicts Upper Airway Patency in Prolonged Tracheostomy Patients
Sponsor: Capital Medical University
Summary
The aim of this study is to evaluate the feasibility of predicting upper airway patency in patients with prolonged tracheostomy using a non-invasive method combining speaking valve (SV) and transtracheal end-expiratory pressure (TTPEE) through a multicenter study.

Conditions
Interventions
Speaking valve combined with airway pressure
All patients wore speaking valves for 30 minutes, during which the transtracheal end-expiratory pressure was measured to assess the patency of the upper airway.
Bronchoscopy
The same examiner performed bronchoscopy on all patients to assess upper airway patency.
