- Primary Outcome Measures
Name Time Method To compare the precision and limits of agreement in the cardiac output measurement using Electric Cardiometry with Arterial Pressure based cardiac output method in patients undergoing major surgeries undergoing General anaesthesiaTimepoint: 1.Baseline (immediately after connecting the devices for CO monitoring) <br/ ><br>2.Intraoperative period <br/ ><br>3.Before and <br/ ><br>4.After completion of a fluid bolus (5mL/kg which is the standard fluid bolus in our institute), administered in case of hemodynamic instability as decided by the treating anaesthesiologist. <br/ ><br>5.Immediately after extubation
- Secondary Outcome Measures
Name Time Method Assessment of Variation of Index of Contractility ( VIC), Thoracic Fluid Content (TFC), Systolic Time Ratio (STR)-Pre ejection period(PEP)/ LV Ejection time(LVET), Index of Contractility( ICON )Timepoint: 1.Baseline (immediately after connecting the devices for CO monitoring) <br/ ><br>2.Intraoperative period <br/ ><br>3.Before and <br/ ><br>4.After completion of a fluid bolus (5mL/kg which is the standard fluid bolus in our institute), administered in case of hemodynamic instability as decided by the treating anaesthesiologist. <br/ ><br>5.Immediately after extubation
