A 48-year-old woman from Singapore reached out to Global Rescue medical operations while at Concordia Camp (15390 feet/4,691 meters) on K2. She reported suffering from symptoms indicative of Acute Mountain Sickness, including colds, cough and difficulty breathing. Her oxygen level was 50%, and the camp doctor assessed her condition as AMS with possible HAPE. The camp doctor prescribed montelukast, cetirizine, DayQuil for nighttime use, and acetaminophen. The member had also been taking Diamox for altitude sickness, but her symptoms persisted. Due to the severity of her condition, Global Rescue medical operations personnel activated an airborne field rescue. The member was successfully evacuated to a hospital in Skardu where she received medical attention and was subsequently discharged.
