SV With TTPEE Measurement Predicts Upper Airway Patency in Prolonged Tracheostomy Patients

Condition(s) studied

Investigational drug(s) / intervention(s)

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.

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.

Eligibility

Primary outcome measure(s)

• The sensitivity and specificity of SV with transtracheal end-expiratory pressure measurement in predicting upper airway patency — The patients started using the SV with the TTPEE measurement on the day of enrollment. After that, bronchoscopy should be performed within 48 hours.
  Patients enrolled in the study will undergo both SV with transtracheal end-expiratory pressure measurement and bronchoscopy. Upper airway non-patency will be defined as positive. Using the results of bronchoscopy as the gold standard, the sensitivity and specificity of SV with transtracheal end-expiratory pressure measurement will be evaluated.
