Efficacy of the Ratio of Respiratory Rate to Diaphragm Thickening Fraction in Prediction of Successful Weaning

the aim of this prospective cross-sectional study is Assessment the effectiveness of the RR/DTF in predicting successful extubation . and to Compare the effectiveness of the RR/DTF with conventional parameters (RSBI, VC, PIMAX) for predicting successful extubation All participants will undergo a SBT by using pressure support ventilation (PSV) with pressure support of 5 cm H2O and positive end-expiratory pressure (PEEP) of 5 cm water (H2O) . The decision to start weaning, extubation or reintubation will be made based on the attending physician's discretion following local guidelines. Daily, patients will be assessed by the attending physician for weaning readiness. Investigators will be informed when the ICU attending decide to extubate.
