BSA (M^2) |
Cardiac Output (Fick) in L/min=
135 ml O2/min/M 2 *BSA
--------------------------------
[13*Hgb*(SaO2-SvO2)]
BSA=body surface area in M 2 ,
Hgb=hemoglobin in g/dL
SaO2 & SvO2=arterial and venous O2 sat (in decimal)
CI standardizes CO for body size
CI=CO/BSA (in L/min/M 2 )
Normal
CO = 4.3-6.3,
CI = 2.5-3.6
