Which of the following conditions could produce a central venous pressure of 9 torr, and a pulmonary artery pressure of 11 torr?
A. excessive airway pressure
B. mitral valve stenosis
C. Cor pulmonale
D. hypervolemia
Answer: C. Cor pulmonale
Explanation :
Normal CVP is approximately 4 or 5 mm Hg. Normal PAP is 14 mm Hg. Since the CVP is high and PAP is low, it tells us that the right heart is not functioning properly and blood cannot flow correctly through it. CVP is the pressure entering the right heart and PAP is the pressure leaving the right heart. Cor pulmonale is a right heart condition.
