Calculate the systemic vascular resistance (SVR) 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

Calculate the right ventricular stroke work (RVSW) for a patient with the following measure-ments: pulmonary artery pressure (PAP) 50/32 mm Hg, cardiac output (C.O.) 4.0 L/min, heart rate (HR) 127/min, and body surface area (BSA) 1.72 m2.
 
  a. 0.11 g-m/m2
  b. 4.5 g-m/m2
  c. 9.5 g-m/m2
  d. 10.2 g-m/m2

Answer to Question 1

ANS: D
SVR = (MAP  CVP)/C.O.  80

Answer to Question 2

ANS: C
RVSW = (MPAP  SV)  0.0136/BSA
