Reshaping respiratory support.

Asymmetric Nasal High Flow Therapy uses an innovative cannula design to enhance pressure and dead-space clearance. In this video, the effect of an asymmetric cannula on dead space clearance is visualized using a lung simulator. On the left, you can see a symmetrical cannula; on the right, an asymmetrical cannula, i.e., the Optiflow+ Duet Interface. The Asymmetric cannula creates unidirectional flow, purging gas and reducing anatomical dead space. 1
