5 thoughts on “What are the causes of lung stasis and lung edema?”
Increased pressure inside the vessels causes extravasation of fluid. The organs involved depend on where the pressure derives – thus, the fluid extravasated into the pericapillary spaces and secondly into the alveoli as a consequence of increase pressure in the pulmonary circulatory system. This is most often the result of either decreased capability of the heart to pump the blood from the left ventricle into the systemic circulation or increased blood volume as may occur with intravenous fluid replacement for example during surgery.
Lung stasis can be a cause of lung edema since accumulation of blood in the pulmonary vessels can lead to extravasation of fluid to the pericapillary spaces and the alveoli. Therefore lung stasis and lung edema can have the same ethiology. However lung edema can also occur without lung stasis for example caused by trauma or toxins (see the non-cardiogenic reasons for lung edema in the link above)

Hi Johanne
Here’s a good description of the causes of lung edema: http://www.mayoclinic.org/diseases-conditions/pulmonary-edema/basics/causes/con-20022485
Does that mean that edema and stases have the same cause? I just wander if they have same ethiology, but distinct pathogenesis?
Amazing info really appreciate you sharing
