Right heart failure - so the right ventricle fails to pump deoxygenated blood to the lungs - the flow goes down, - more time to extract oxygen - so venous blood has lots of CO2 and super low O2 content- because right heart does not pump this venous blood well it must accumulate somewhere - like in the small venules.

This is what I think...
