Echocardiographic Cardiac Output:

CO = LVOT Area × VTI × HR / 1000

LVOT Area = π × (LVOT Diameter / 2)^2

CI = CO / BSA

SVR = (MAP - CVP) / CO × 80

SVRI = SVR × BSA

Fick's Principle Cardiac Output:

CO = VO2 / ((CaO2 - CvO2) × 10)

CaO2 = Hb × 1.34 × Arterial Saturation

CvO2 = Hb × 1.34 × Venous Saturation

CI, SVR, and SVRI calculations are similar to the Echocardiographic method.
