A 54-year-old member from the United States showed alarming signs of high-altitude cerebral edema while at Concordia in the Karakoram Range. His symptoms included confusion, hallucinations, vomiting, diarrhea and difficulty breathing, with a critically low SpO₂ reading of 61 percent. Global Rescue medical personnel reviewed his condition and advised an immediate helicopter evacuation. Due to weather and permit delays, the evacuation was completed the following day as part of a combined mission with another affected member. Both were transported to a hospital in Skardu for evaluation. The member was treated with supportive care and medications, and his symptoms resolved within days. He declined further monitoring after confirming his condition had stabilized and planned to return to the United States as scheduled.
