Which of the following hemodynamic parameter that is not within normal limits?
a. Cardiac index (CI) = 4 L/min/m2
b. Mixed venous oxygen content (CO2) = 10 vol%
c. Mean arterial pressure (MAP) = 18 mm Hg
d. Pulmonary vascular resistance (PVR) = 200 dyne ? sec ? cm?5
ANS: C
The normal values for the hemodynamic parameters in this question are: Cardiac index (CI) = 2.5-4 L/min/m2, mixed venous oxygen content (CO2) = 15 vol%, mean arterial pressure (MPAP) = 10-20 mm Hg, and pulmonary vascular resistance (PVR) =100-250 dyne ? sec ? cm−5. The value that is not within normal limits is the CO2.
