Official title
Diaphragmatic Rapid Shallow Breathing Index (D-RSBI) Versus Traditional Rapid Shallow Breathing Index (RSBI) for Prediction of Weaning Success From Mechanical Ventilation in COPD Patients
Overview
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.
Primary outcome measures
- AUROC of D-RSBI for prediction of successful weaning [Time frame: Within 72 hours after extubation]
Secondary outcome measures (2)
- AUROC of conventional RSBI for prediction of successful weaning. [Time frame: Within 72 hours after extubation]
- Difference between AUROC values of D-RSBI and conventional RSBI [Time frame: Within 72 hours after extubation]
Eligibility criteria
Inclusion criteria
- 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 .
- Preserved mental status and ability to initiate spontaneous breathing.
- Successful tolerance of spontaneous breathing trial conducted on CPAP mode with pressure support ≤ 8 cmH2O.
Exclusion criteria
- Refusal of consent
- Neuromuscular disease, phrenic nerve palsy, or diaphragmatic paralysis.
- Large pneumothorax or pathology interfering with ultrasound assessment.
- Terminal extubation.
- Recent major thoracic surgery.
- Poor sonographic window despite repeated attempts.
