Hemodynamics
All subjects were indwelled with internal jugular vein catheter and femoral artery catheter for PICCO monitoring after hospitalization. Baseline hemodynamic data, including heart rate (HR), systolic pressure (SBp), diastolic pressure (DBp), mean arterial pressure, (MBp), cardiac Index (CI), central venous pressure (CVP), left ventricular contractility index (dP/dtmax), global ejection fraction (GEF), global end-diastolic volume Index (GEDVI) and extravascular lung water index (ELWI), were recorded at 0 h, 24 h, 48 h, 72 h, 96 h and 7d.
