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

Dennett denies Nagel's claim that the bat's consciousness is inaccessible, contending that any "interesting or theoretically important" features of a bat's consciousness would be amenable to third-person observation. For instance, it is clear that bats cannot detect objects more than a few meters away because echolocation has a limited range. He holds that any similar aspects of its experiences could be gleaned by further scientific experiments. What Is it Like to Be a Bat? "What is it like to be a bat?" is a paper by American philosopher Thomas Nagel, first published
