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.

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
