About this trial
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.
Eligibility criteria
Qualifiers
Mechanically ventilated COPD patients fulfilling standard weaning readiness criteria.
Invasive mechanical ventilation for more than 24 hours before spontaneous breathing trial.
Hemodynamically stable without significant vasopressor support.
Adequate oxygenation with FiO2 ≤ 0.5 and PEEP ≤ 8 cmH2O .
Disqualifiers
Refusal of consent
Neuromuscular disease, phrenic nerve palsy, or diaphragmatic paralysis.
Large pneumothorax or pathology interfering with ultrasound assessment.
Terminal extubation.
