Pulmonary Artery Catheter (PAC) Accuracy and Efficacy Compared with Flow Probe and Transcutaneous Doppler (USCOM): An Ovine Cardiac Output Validation

Figure 6

ROC curve for 70% certainty of detection of 5% increase in CO from baseline with PAC in red (AUC=0.524), USCOM in blue (AUC=0.708). Random values are represented by the dotted line (AUC=0.50) and clinical effectiveness AUC≥0.70.
