II.Left ventricular failure
III.High pulmonary vascular resistance
IV.Hypovolemia

Question

Quizplus · Accepted Answer

The PAP might be high because of excessive blood volume (hypervolemia), or because of left ventricular pumping failure in which blood dams up in the entire pulmonary circulation. The PAP might also be high as a result of high pulmonary vascular resistance (PVR). High pressures in either ventricle at the end of diastole, coupled with a low cardiac output, signal a loss of ventricular pumping ability, or a loss of contractility.
