D-RSBI Versus RSBI for Predicting Weaning Success in COPD Patients
Recruiting · NCT07590362 · Observational (researchers observe without assigning treatment) · Lead sponsor: Sohag University
View the official record on ClinicalTrials.gov →What this trial is about
This prospective observational cohort study aims to compare the predictive accuracy of diaphragmatic rapid shallow breathing index (D-RSBI) versus traditional rapid shallow breathing index (RSBI) for predicting weaning success from invasive mechanical ventilation in COPD patients. Diaphragmatic ultrasound measurements will be performed during spontaneous breathing trials, and patients will be followed for 72 hours after extubation to assess weaning outcomes.
