2) Increased pulmonary vascular resistance (PVR)
3) Decreased mean pulmonary artery pressure (PA)
4) Decreased cardiac output (CO)

B)2, 3
C)1, 2, 3
D)1, 2, 3, 4

Question

Quizplus · Accepted Answer

Pulmonary edema is caused by an accumulation of fluid in the lungs, which can lead to an increase in the pulmonary capillary wedge pressure (PCWP). This increase in pressure can result in a decrease in cardiac output (CO) as the heart has to work harder to pump against the increased resistance. However, there is no consistent effect on pulmonary vascular resistance (PVR) and mean pulmonary artery pressure (PA). Therefore, the correct answer is A, which includes the changes in PCWP and CO.
