A Comparative Study to evaluate Diaphragmatic Rapid Shallow Breathing Index and Diaphragmatic Thickness Fraction for prediction of successful weaning in critically ill patients.

Many parameters are used to predict patients ability to breath spontaneously during weaning from ventilatory support like diaphragmatic rapid shallow breathing index, diaphragmatic thickness fraction, diaphragmatic excursion , lung ultrasound score but there is lack of data regarding which parameter is best among them for predicting successful weaning in such patients, so we are going to a comparative observational study to know which parameter better poredicts tge outcome of weaning in ventilator supported patients.
