Henry Heimlich year of age, as does the National Safety Council. The 2005 choking-rescue guidelines published by the American Heart Association called the procedure "abdominal thrusts". The new guidelines stated that chest thrusts and back blows may also deal with choking effectively. In spring 2006, the American Red Cross "downgraded" the use of the Heimlich maneuver, essentially returning to the pre-1986 guidelines. For conscious victims, the new guidelines (nicknamed "the five and five"), recommend first applying five backblows; if this method fails to remove the airway obstruction, rescuers will then apply five abdominal thrusts. For unconscious victims, the new guidelines recommend chest

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
