No results posted yet for this study

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

  • Tracheostomy

Interventions

DIAGNOSTIC_TEST

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.

DIAGNOSTIC_TEST

Bronchoscopy

The same examiner performed bronchoscopy on all patients to assess upper airway patency.
