A member from Florida suffering symptoms of Altitude Mountain Sickness (AMS) needed a helicopter rescue from Dingboche (14,470 ft/4,410 m), a popular stop for trekkers and climbers headed to Mount Everest, Ama Dablam or Imja Tse. The expedition leader contacted Global Rescue operations reporting the member’s oxygen saturation level was 53% — well below the normal range of 95% to 100%. Supplemental oxygen elevated the member’s level to 83% but she remained weak and experienced continued difficulty breathing. The Global Rescue operations team initiated an airborne rescue and transport of the member to a nearby hospital. The hospital’s treating physician confirmed an AMS diagnosis and provided supplemental oxygen and a dexamethasone tab. Feeling better, the member traveled to Kathmandu for further medical evaluation and reported feeling stable.
