During an attempt to summit Aconcagua, a U.S. member began suffering from weakness, labored breathing and oxygen desaturation. Expedition leaders contacted Global Rescue and, following an evaluation by medical personnel, the member was placed on a supplemental oxygen and given medication to treat his condition. His symptoms persisted despite treatment. Global Rescue arranged for an airborne medical transport off the mountain due to the ongoing severity of the member’s condition. He was successfully transported to a hospital where medical professionals evaluated and diagnosed him with HAPE. He was discharged later the same day following medical treatment.
