High-altitude pulmonary edema (HAPE) generally occurs in those who don't first become acclimated to the elevation (which can take from a few days to a week or so). Pulmonary edema may be secondary to decreased oncotic pressure found with hypoalbuminemia, and can be secondary to lymphatic insufficiency. Pulmonary edema.

Pulmonary edema occurs when fluid builds up around the lungs. Background Patients with acute pulmonary edema often have marked hypertension but, after reduction of the blood pressure, have a normal left ventricular ejection fraction (≥0.50). High-altitude pulmonary edema (HAPE) generally occurs 2-4 days after rapid ascent to altitudes in excess of 2500 m (8000 ft). Heart problems are commonly associated with the pathophysiology of edema in the lungs. Consider non-cardiac and other causes for the patient's symptoms. (H&E, ob.

This process leads to diminished gas exchange at the alveolar level, progressing to potentially causing respiratory failure. edema paru By, Reshmi Unni DEFINITION Pulmonary edema is the abnormal accumulation of fluid in the interstitial spaces surrounding the alveoli with the advancement of fluid accumulation in the alveolar spaces. High-altitude pulmonary edema (HAPE) is a life-threatening form of non-cardiogenic pulmonary edema (fluid accumulation in the lungs) that occurs in otherwise healthy people at altitudes typically above 2,500 meters (8,200 ft).
