High Altitude Pulmonary Edema

High Altitude Pulmonary Edema (HAPE) is a potentially serious condition that occurs when fluid accumulates in the lungs after rapidly ascending to high elevations, usually above 8,000 feet. The reduced oxygen levels at high altitude cause blood vessels in the lungs to constrict, increasing pressure and leading to fluid leakage into the lung tissues. Symptoms include shortness of breath, cough, weakness, and a feeling of tightness in the chest. Prompt recognition and descent to lower altitude, along with oxygen therapy and medical treatment, are crucial to prevent severe complications and ensure recovery.
