Diaphragmatic excursion assessment by ultrasound versus volume associated weaning parameters as a prediction in extubation in critically Ill patients

ABSTRACT

Background: Liberating a patient from ventilator is a continuous process as with any disease condition which starts with recognition of patient being ready to be weaned from ventilator by letting the patient breathe on T-piece and, if successful proceeding to SBT followed by extubation, if it is tolerated well [simple weaning]. Otherwise letting patient on ventilator till next such trial being successful. Difficulty in weaning from mechanical ventilation is one of the most frequently encountered problems in MICU. An estimated 20% of mechanically ventilated patients face failed extuabtion [requiring reintubation within 48 h of extuabtion]
