- Evaluations of inhaler use have demonstrated that mishandling of MDIs is commonplace.
- One of the most common errors is the failure to coordinate inhalation with actuation of the inhaler
- One of the reasons why VHCs are often prescribed, is to reduce the severity of this error
- This Functional Respiratory Imaging (FRI) based study assessed the likely severity of a short inhalation delay (from actuation) with an MDI alone and how it contrasted to the use with a VHC
