  1. RMSE root mean square error, MAPE mean absolute percentage error, SVR systemic vascular resistance, SVRf0, SVRf5, SVRf10, SVRf15, and SVRf20, SVRs calculated using fixed central venous pressures of 0, 5, 10, 15, and 20 mmHg, respectively; SVRr, SVR calculated using random central venous pressure ranging from 5 to 15 mmHg
  2. aSVRf10 was found to be the most accurate of these SVRs
