Henry Judah Heimlich was an American thoracic surgeon and medical researcher. He is widely credited as the inventor of the Heimlich maneuver, a technique of abdominal thrusts for stopping choking, described in Emergency Medicine in 1974. He also invented the Micro Trach portable oxygen system for ambulatory patients and the Heimlich Chest Drain Valve, or "flutter valve", which drains blood and air out of the chest cavity.
