Asthma control and global warming are important issues that have significant impacts on human health and the environment.

It is critical however to ensure that maintaining or improving the patient’s asthma control goes hand in hand with environmental actions.

This lab study investigated how to optimize the modelled lung delivery while at the same time minimizing the carbon emissions from the MDI.

Conclusions:

• The most efficient and effective delivery method remains that recommended in the device IFU (one actuation inhaled at a time, as well inhalation as soon as possible after actuation)
• However, this laboratory-based study has indicated that a modified common-canister protocol with an anti-static VHC as the aerosol transfer vehicle has the potential to be a viable ‘off-label’ proposition in hospital situations where there is an urgent need to conserve pMDI medication as well as avoid cross-contamination from pathogenic viruses or bacteria

This lab study compared a number of VHCs for patient usability and safety factors. 

As a medical device manufacturer, we are committed to minimizing any disruption to the supply of our products to our customers globally, during this unprecedented time with the outbreak of COVID-19.
