A member asked:

How is pulmonary vascular congestion caused?

A doctor has provided 1 answer

Usually from CHF: Vascular congestion or pulmonary edema is usually the result of a cardiac problem call congestive heart failure (chf). The left side of the heart can not keep up with the right, so blood stagnates in the lungs. This causes shortness of breath, inability to lie flat, and sometimes white frothy sputum.
