Receiver operator characteristic curve for prediction in
weaning from ventilator
The ROC curve was analyzed by selecting the maximum pulmonary pressure
during follow-up. The area under
the curve (AUC) for ventilator weaning was 0.99.
The
best cutoff value for PASP for predicting the success of ventilator
weaning was 39.50 mmHg, yielding a sensitivity of 100% and a
specificity of 96.15% (Figure 4).
