Henry Heimlich choking-rescue guidelines of the American Heart Association and of the American Red Cross taught rescuers to first perform a series of backblows to remove the FBAO (foreign body airway obstruction); if backblows failed, then rescuers learned to proceed with the Heimlich maneuver (aka "abdominal thrusts"). After a July 1985 American Heart Association conference, backblows were removed from choking-rescue guidelines. From 1986 to 2005, the published guidelines of the American Heart Association and the American Red Cross recommended only the Heimlich maneuver as the treatment for choking; the National Institutes of Health still does apply it for conscious persons over one
Henry Heimlich thrusts, a method first recommended in a 1976 study by Charles Guildner, with results duplicated in a year 2000 study by Audun Langhelle. The 2006 guidelines also eliminated the phrase "Heimlich maneuver" and replaced it with "abdominal thrust". Allegations of case fraud have dogged Heimlich's promotion of abdominal thrusts as a treatment for drowning. The 2005 drowning rescue guidelines of the American Heart Association did not include citations of Heimlich's work and warn against the use of the Heimlich maneuver for drowning rescue as unproven and dangerous, due to its risk of vomiting leading to aspiration. In 2003, Heimlich's colleague
