Validation of an Effort-Based Cough Peak Flow Algorithm to Predict Extubation Outcomes

NCT07737483 · Status: NOT_YET_RECRUITING · Type: OBSERVATIONAL · Enrollment: 150

No results posted yet for this study

Summary

This study aims to prospectively validate the diagnostic accuracy of an effort-stratified Cough Peak Flow (CPF) decision algorithm for predicting extubation failure, maintaining strict blinding of the clinical team. The model classifies patients by neurological status and uses an effort-based approach, including a "Gray Zone" (40-59 L/min) managed by tidal volume evaluation.

Conditions

  • Extubation Failure

Interventions

DIAGNOSTIC_TEST

Observational measurement of Cough Peak Flow and Tidal Volume

Patients undergo standardized CPF and pre-cough tidal volume (VT) measurements prior to extubation. Measurements are stratified by cooperation level (Voluntary vs. Reflex).
