(ART mean-CVP) / CO) x 79.96,
Or,

NOTE: When an IBP channel is labeled RA
and no other IBP channel is labeled
CVP, the RA value is used in
calculating SVR and RVSW.

Coronary Perfusion Pressure = Diastolic ART Blood
Pressure - PAWP
EDV (ml) End-Diastolic Volume End Diastolic Volume = SV / (EF / 100%)
EDVI (ml/m²) End-Diastolic Volume
Index
End Diastolic Volume Index = EDV / BSA
ESV (ml) End-Systolic Volume End Systolic Volume = EDV - SV
ESVI (ml/m²) End-Systolic Volume -
