When you choke dogs, you have to sidestep the medical establishment
Strangling a dog is exactly what Dr. Heimlich did in 1973, when he set out to discover his maneuver. After several failed attempts, Heimlich finally found the exact technique needed to eject the tube from the dog's throat. Once the maneuver showed consistent promise, he replaced the tube with pieces of meat, garnering the same exciting results (and, probably, sad puppy) as before.
The Heimlich maneuver was a success... on dogs. How does one test a technique that's designed to be performed on a human facing imminent death? Heimlich decided on an alternative method: rather than going the traditional route of trials, peer-reviewed studies, and other medical protocols, he wrote an informal article, in which he asked readers to attempt his maneuver should the need arise, then report the results directly to him. With this brilliant maneuver (GET IT?), Heimlich had found his human test subjects -- no tubes, grant proposals, puppies, or labs required.
Heimlich Mania sweeps the nation!
As the testimonials rolled in -- thanks in no small part to Heimlich's strategic partnerships with syndicated columnists -- Heimlich's celebrity spread. Despite the increased press coverage, the American Red Cross refused to replace the choking protocol of back blows with the Heimlich maneuver, due to a lack of scientific evidence. The maneuver seemed stuck.
