HI = Hemodynamic Index; MAP = Mean arterial pressure; PCWP= pulmonary capillary wedge pressure; CVP = central venous pressure; RPM = Revolutions per minute
This formula was developed with the primary intention to obtain an index that, integrating the afterload value represented by the mean arterial pressure (MAP), the ratio between the right (CVP) and left (PCWP) filling pressures and the ratio between the number of RPM set and the maximum RPM available for the HM3, could provide a parameter representing a specific hemodynamic profile.
