About this trial
The aim of this study is to evaluate the use of diaphragmatic ultrasonography in taking mechanical ventilation weaning decision and predicting outcome in Chronic obstructive pulmonary disease patient.
Primary outcome:
• Number of patients with failed weaning trial and need reintubation.
Secondary outcomes:
* Time till extubation trial. * Ventilation free days after extubation less or more than 48h . * Number of Intensive care unit discharges. * Sensitivity and specificity of diaphragmatic assessment as a predictor of weaning.
