Receiver operating characteristic curves of PAWP at supine position, PAWP at leg raise, DPG at supine position, PVR at supine position and RC-time at supine position. AUC, area under the curve; DPG, diastolic pulmonary pressure gradient; PVR, pulmonary vascular resistance; RC time, pulmonary circulation time constant, PAWP, pulmonary artery wedge pressure .
