A person experiences chest pain and arm pain while driving alone, which may be a heart attack. They are only 5 miles from the hospital but unsure if they can make it. The document recommends coughing repeatedly and vigorously while taking deep breaths every 2 seconds to keep the blood circulating until help arrives or the heart returns to normal. Coughing squeezes the heart to help blood continue flowing in a potential heart attack situation when medical assistance is not immediately available.
