Hemodynamic Parameters
Formulas
| Pulse Pressure = SAP Systolic - SAP Diastolic |
|
mean SAP = (SAP Systolic + 2*SAP Diastolic)/3 |
| mean PAP = (PAP Systolic + 2*PAP Diastolic)/3 |
|
SV Index = SV/BSA |
| Cardiac Output = (SV * HR) / 1000 |
|
Cardiac Index = CardiacOutput/BSA |
| BSA = (cm^0.718)*(kg^0.427)*0.007449 |
|
SVR = (meanSAP-meanRAP)*80/CardiacOutput |
| PVR = (meanPAP - Wedge Pressure)*80/CardiacOutput |
|
