Pulmonary Edema Diagram. The pulmonary wedge pressure pwp also called pulmonary arterial wedge pressure pawp pulmonary capillary wedge pressure pcwp pulmonary artery occlusion pressure paop or cross sectional pressure is the pressure measured by wedging a pulmonary catheter with an inflated balloon into a small pulmonary arterial branch. Microscopic pathology this is a low power photomicrograph of lung from this case.
A mechanical injury of the barrier due to increased hydrostatic pulmonary capillary pressures and b. Pathophysiology of oedema shama rani paul 2. 11 12 therefore hydrostatic and high permeability pulmonary edema may represent the extremes in the spectrum of pulmonary edema.
Although the heart is not enlarged the cause was still on a cardiogenic basis.
Pulmonary edema occurs when the net flux of fluid from the vasculature into the interstitial space is increased. Pulmonary edema lung problem vector illustration diagram. First cardiogenic or hydrostatic pulmonary edema from as the name implies an elevated pulmonary capillary pressure from left sided heart failure. Although pulmonary edema is traditionally separated into two categories according to cause cardiogenic andnoncardiogenic the end result of both processes is a net fluid accumulation within the interstitial and alveolar spacesnoncardiogenic pulmonary edema in its most severe state is.
