Diaphragm ultrasound as a predictor of successful extubation from mechanical ventilation [1]
This study evaluated the use of ultrasound to assess diaphragm thickening, rather than diaphragm motion, to predict extubation success. Measurements were made in 63 ventilated patients, end-expiration and end-inspiration differences in thickness during spontaneous breathing were calculated, and the outcome was extubation within 48 hr. The ROC AUC was 0.79 for assessing weaning success (79% accuracy).
