Freediving - Glossopharyngeal Breathing The process of glossopharyngeal insufflation, consists of the following steps :

First with the glottis and soft palate closed, and the tongue flattened against the lower part of the mouth, open the lips and lower the jaw, sucking air into the mouth. Without raising the jaw, close the lips to seal the air in the mouth and upper throat. Then, opening the glottis, raise the jaw and tongue to push the air into the lungs, and then close the glottis. This process can be repeated as necessary to inflate the lung as desired.

It is important to note that this process is not without serious risk, so should only be attempted after proper training, with appropriate caution, and under the supervision of a physician or other appropriately trained individual. Excessive glossopharyngeal insufflation "is known to have caused various ailments, including, but not limited to, air in the arteries (air embolism), air between the lungs (pneumomediastinum), pneumothorax, and lung bleeding. All of these ailments can be potentially fatal when insufficiently recognized and treated."
