Calculate the pulmonary vascular resistance (PVR) given the following measurements obtained during a hemodynamic study:
pulmonary artery pressure (PAP) = 40/22 mm Hg, pulmonary artery occlusion pressure (PAOP) = 12 mm Hg, blood pressure (BP) = 156/80 mm Hg, central venous pressure (CVP) = 19 mm Hg, cardiac output (C.O.) = 4.8 L/min, and heart rate (HR) = 68 beats/min.
a. 150 dyne sec cm5
b. 267 dyne sec cm5
c. 317 dyne sec cm5
d. 1496 dyne sec cm5
Question 2
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 output (C.O.) = 5.7 L/min, and heart rate (HR) = 75 beats/min. Calculate this patient's systemic vascular resistance (SVR).
a. 295 dyne sec cm5
b. 393 dyne sec cm5
c. 800 dyne sec cm5
d. 1165 dyne sec cm5
