title: The role of the thoracic compression reflex in the Heimlich Maneuver.
abstract: Using the dog as an experimental model, the relationship of the Thoracic Compression Reflex (TCR) to the Heimlich Maneuver (HM) was examined. TCR was equally effective as lateral chest compression in relieving artificially induced choke. Destruction of the TCR by vagotomy rendered relief of choke by HM ineffectual in 5 of 8 dogs. It was concluded TCR may be a factor in HM, but that mechanical compression of the lungs is also involved.
