A U.S. member needed a field rescue after experiencing a sharp, stabbing pain on the left side of his chest during a boat trip in the Amazonas region of Brazil. Doses of aspirin alleviated some discomfort, but the pain persisted overnight and into the morning. Global Rescue medical operations initiated a field rescue. Unfortunately, no float planes or helicopter transports were available. Ultimately, ground transport was arranged and successfully conveyed the member to an airport where a cardiologist met with him for an examination and evaluation. The physician accompanied the member to a hospital in Manaus. Following an array of diagnostic tests the member was treated for hypertension, yet the cause of his chest pains was inconclusive based on the test results. He made an appointment with his cardiologist in the U.S. and based on his improving condition, felt confident to return home.
