Podcast 622: High Altitude Pulmonary Edema (HAPE)

Contributor: Thomas Seibert, MD

Educational Pearls:

  • High Altitude Pulmonary Edema (HAPE) typically occurs 2-4 days after arriving at elevation
  • Symptoms include:
    • Fatigue
    • Dyspnea
    • Cough
  • Treatment includes:
    • Descent to lower elevation 
    • Oxygen supplementation
    • Nifedipine
  • Caused by sympathetic stimulation from hypobaric hypoxic exposure, causing uneven pulmonary vasculature constriction and when paired with a leaky endothelium, pulmonary edema. #science
