Summary:

Presented at DDL 2017 in Edinburgh

• Valved holding chambers are widely prescribed to assist patients receiving inhaled medications by avoiding losses caused by imperfect coordination of inhalation and actuation and also to reduce oropharyngeal deposition.
• Regardless of whether using a solution based formulation (like Qvar) or a suspension formulation (Flovent), the use of a valved holding chamber reduced the amount of medication deposited in the mouth (oropharynx) and increased the potential for lung delivery
• This study can be used to help demonstrate the value of using a valved holding chamber for both solution and suspension formulated metered dose inhalers and for all patient populations, including adults

Conclusions:

The continuous involvement of patients resulted in a number of key insights that helped guide the design process, resulting in the development of a chamber that patients are much more likely to use while on-the-go.

Development of a Prototype Patient Respiratory Management Mobile Health Application Using Validated Tools to Assess User Experience

PRESENTED AT VIRTUAL ATS 2020

• 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
