Glossopharyngeal Breathing

Glossopharyngeal breathing (also known as “frog breathing ) is a form of positive pressure ventilation produced by the patient's voluntary muscles where boluses of air are forced into the lungs.

It is a trick movement that was first described by Dail (1951) when patients with poliomyelitis were observed to be gulping air into their lungs. It was this gulping action that gave the technique the name 'frog breathing'.
