A 36-year-old member from the United States began experiencing serious altitude sickness while staying at Barranco Camp on Kilimanjaro. She presented with a pounding headache, vomiting episodes and low oxygen saturation, along with a high heart rate. These symptoms were strongly indicative of acute mountain sickness and possibly high-altitude cerebral edema, a life-threatening condition if not treated quickly. Because of the elevated risk and lack of proper medical infrastructure in the area, Global Rescue arranged a helicopter evacuation to a regional medical facility. Upon arrival, she underwent evaluation, received oxygen support and began medical therapy. Her condition rapidly improved. Later that day, she was discharged and continued recovery at a nearby hotel. The member and her husband made plans to return home a few days later. Timely intervention ensured full recovery without complications.
