Edema Edema Edema, also spelled oedema or œdema, is an abnormal accumulation of fluid in the interstitium, located beneath the skin and in the cavities of the body, which can cause severe pain. Clinically, edema manifests as swelling. The amount of interstitial fluid is determined by the balance of fluid homeostasis and the increased secretion of fluid into the interstitium. The word is from Greek "oídēma" meaning "swelling". The condition is also known (mostly archaic) as dropsy. Cutaneous edema is referred to as "pitting" when, after pressure is applied to a small area, the indentation persists after the release of the
Pulmonary edema parenchyma of the lung. The acute lung injury-acute respiratory distress syndrome (ALI-ARDS) covers many of these causes, but they may include: Some causes of pulmonary edema are less well characterised and arguably represent specific instances of the broader classifications above. "Flash pulmonary edema" ("FPE"), is rapid onset pulmonary edema. It is most often precipitated by acute myocardial infarction or mitral regurgitation, but can be caused by aortic regurgitation, heart failure, or almost any cause of elevated left ventricular filling pressures. Treatment of FPE should be directed at the underlying cause, but the mainstays are ensuring adequate oxygenation, diuresis, and decrease
