Which of the following is the hemodynamic measurement that is indicative of a patient with right heart failure?
a. Pulmonary artery occlusion pressure (PAOP) = 12 mm Hg
b. Central venous pressure (CVP) = 16 mm Hg
c. Pulmonary artery pressure (PAP) = 35/15 mm Hg
d. Mean arterial pressure (MAP) = 80 mm Hg
ANS: B
The normal range for pulmonary artery occlusion pressure (PAOP) is 5-12 mm Hg, for central venous pressure (CVP) 2-6 mm Hg, for pulmonary artery pressure (PAP) 15-35/5-15 mm Hg, and for mean arterial pressure (MAP) 70-100 mm Hg. Right heart failure causes the CVP to increase significantly. Answer B shows a CVP that is greatly increased and is therefore indicative of right heart failure.
