Which statement about High Altitude Pulmonary Edema management is true?

• A. Descent and supplemental oxygen are essential
• B. Antibiotics are standard therapy
• C. High-altitude ascent accelerates recovery
• D. Diuretics alone cure HAPE

Answer: (A)

When HAPE occurs, the most effective immediate action is to relieve the hypoxic stress and reduce the pulmonary pressures driving fluid into the lungs. Descent to a lower altitude removes the trigger of hypoxic vasoconstriction and high capillary pressures, while supplemental oxygen directly improves blood oxygen levels and helps lower pulmonary arterial pressures, stabilizing the edema. This combination addresses both the cause and the symptoms, making it the best initial management. Antibiotics aren’t part of standard HAPE treatment because the edema is noninfectious. Asking the patient to ascend further worsens the condition, whereas descending is protective. Diuretics alone don’t resolve HAPE and can worsen dehydration or electrolyte imbalance.
