Diaphragm ultrasound as a predictor of successful extubation from mechanical ventilation [1]
This prospective study evaluated changes in diaphragm thickness during weaning trials in ventilated patients as a predictor of successful weaning. An increase in thickness of more than 30% between end-expiration and end-inspiration had a positive predictive value of 91% and an area under the ROC curve of 0.79.
