Acute mountain sickness is a condition affecting otherwise healthy individuals on going rapidly to altitude. ), pp. Milledge JS. HAPE is the most common cause of death related to high altitude. In severe cases, there may be a tendency to form more confluent changes which can eventually involve the entire lung parenchyma. High-altitude pulmonary edema. Vock P, Brutsche MH, Nanzer A et-al. Because pulmonary edema requires prompt treatment, you'll initially be diagnosed on the basis of your symptoms and a physical exam, electrocardiogram and chest X-ray.Once your condition is more stable, your doctor will ask about your medical history, especially whether you have ever had cardiovascular or lung disease.Tests that may be done to diagnose pulmonary edema or to determine why you developed fluid in your lungs include: 1. x�b```b``ue`e`�`d@ A��K'f�K���kOЊ��~��*3�V����]A����A� �n�}�,�^�� High-altitude pulmonary edema (HAPE) is a life-threatening, noncardiogenic form of pulmonary edema afflicting certain individuals after rapid ascent to high altitude above 2,500 m (approximately 8,200 ft).
