Calculate the right ventricular stroke work (RVSW) given the following patient data: pulmonary artery pressure (PAP) = 35/25 mm Hg, cardiac output (C.O.) = 3.6 L/min, heart rate (HR) = 107 beats per minute, and body surface area (BSA) is 1.6 m2.
 
  a. 1.7 g-m/m2
  b. 6.2 g-m/m2
  c. 7.1 g-m/m2
  d. 30.5 g-m/m2

Question 2

The hemodynamic values for a patient in the cardiovascular care unit are: blood pressure (BP) 96/60 mm Hg, pulmonary artery pressure (PAP) 29 mm Hg, pulmonary capillary wedge pressure (PCWP) 14 mm Hg, stroke volume (SV) 50 mL.
 
  The patient has a body surface area of 1.6 m2. Calculate the patient's left ventricular stroke work (LVSW).
  a. 12.3 g-m/m2
  b. 30.6 g-m/m2
  c. 33.2 g-m/m2
  d. 49 g-m/m2
