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).
