A Japanese member needed field rescue from Aconcagua after experiencing HAPE-like symptoms including shortness of breath, oxygen desaturation and bibasal crackles – the bubbling or crackling sound originating from the base of the lung. Global Rescue Operations was notified and reviewed the on-mountain medical evaluation. A helicopter field rescue was recommended and initiated to transport the member off the mountain. Ambulance transportation was also arranged to accommodate the need for oxygen support and close monitoring before successful arrival at a hospital in Mendoza, Argentina. The member was examined and diagnosed with pulmonary edema and admitted for treatment. He was later discharged and decided to remain in Argentina until his scheduled flight home.
