Pulmonary edema cardiac arrest due to hypoxia. It is a cardinal feature of congestive heart failure. The term edema is from the Greek (oídēma, "swelling"), from οἰδέω (oidéō, "I swell"). The most common symptom of pulmonary edema is difficulty breathing, but may include other symptoms such as coughing up blood (classically seen as pink, frothy sputum), excessive sweating, anxiety, and pale skin. Shortness of breath can manifest as orthopnea (inability to lie down flat due to breathlessness) and/or paroxysmal nocturnal dyspnea (episodes of severe sudden breathlessness at night). These are common presenting symptoms of chronic pulmonary edema due to left ventricular failure.
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
