Why the Jaw Thrust?


The biggest impediment, after placement of an oral airway, is the relaxation of the soft tissue structures in the hypo-pharynx. These structures are inclined to collapse, thus obstructing airflow, while occurring from both front-to-back and side-to-side, thus greatly decreasing the size of the oral opening.

 

In relation, literally every patient before and after anesthesia, CPR, or sedation, is provided with a jaw-thrust as they wake up to prevent the tongue from falling back and obstructing the airway. Furthermore, almost every patient intubated is provided with an airway to prevent biting of the soft endotracheal tube and the tongue. Both of these procedures involve protracting the lower jaw by pulling it forward relative to the upper jaw to open the airway.

Since current airways don’t sufficiently address these known physiological issues – we asked ourselves, why not address these drawbacks and engineer and design a better airway?
