Facemask Testing

Many spacers/VHCs and nebulisers are used with facemasks instead of mouthpieces to administer the inhaled aerosol. This practice is commonplace in the case of infants and small children and in situations where the user lacks the capability of using a mouthpiece.
One of the main factors influencing the amount of inhaled drug available to the patient is the interface between the facemask and the patient. Investigating and defining the effect of a facemask to the product's DDU and APSD is important for the product development.
