As current MDIs contain hydrofluorocarbon propellants, it would be beneficial to find ways to reduce carbon emissions without compromising patient safety.

This lab study investigated a way to optimize the modelled lung dose per actuation while at the same time minimizing the carbon emissions from the MDI

Efficacy is a major aspect when selecting an OPEP device for airway clearance.

This study was presented at the North American Cystic Fibrosis Conference 2022.
