Left ventricular failure often results in increased net pulmonary capillary filtration into the interstitial fluid of the lungs and a resulting decrease in the diffusional exchange of O2 and CO2 between lung and blood.

Question

Quizplus · Accepted Answer

Left ventricular failure causes a buildup of pressure in the pulmonary vessels, leading to increased filtration of fluid into the interstitial spaces of the lungs. This can impair gas exchange between the alveoli and the pulmonary capillaries.
