The following hemodynamic measurements were obtained from a patient in the intensive care unit: pulmonary artery pressure (PAP) = 67/25 mm Hg, pulmonary artery occlusion pressure (PAOP) = 18 mm Hg,
blood pressure (BP) = 100/50 mm Hg, central venous pressure (CVP) = 17 mm Hg, cardiac out-put (C.O.) = 5.7 L/min, and heart rate (HR) = 75 beats/min. Calculate this patient's pulmonary vascular resistance (PVR).
a. 295 dyne ? sec ? cm?5
b. 393 dyne ? sec ? cm?5
c. 800 dyne ? sec ? cm?5
d. 1165 dyne ? sec ? cm?5
ANS: A
PVR = [(MPAP − MLAP)/PBF] ? 80
