A member from Altadena, United States, was at Camp 3 on Ama Dablam in the Khumjung region of Nepal, at approximately 20,670 feet/6,300 meters, when her guide reported symptoms of acute mountain sickness with concern for high altitude cerebral edema. She experienced dizziness, headache, vomiting, weakness, chest pain, difficulty breathing and inability to move. Because Camp 3 did not have a safe landing area for a helicopter, the operations team instructed the climbing team to descend to a higher but more suitable camp or to base camp, although poor weather delayed the descent. Later she confirmed that she had reached Kathmandu and was recovering. The helicopter provider subsequently confirmed that she had been transported from Camp 3 to Lukla using a hover landing technique, and senior management approved coverage of the field rescue cost. The member continued her recovery in Kathmandu.
