Guiding Inspiratory Flow: Development of the In-Check DIAL G16, a Tool for Improving Inhaler Technique

Figure 1

In-Check DIAL G16 (Clement Clarke International Limited). In-Check DIAL G16 is a multipatient clinic/pharmacy device using disposable, single-patient mouthpieces and is used for assessing the inspiratory effort of a patient inhaling through a selected inhaler. The DIAL can be set to resemble the resistance of the inhaler, and the appropriate inhalation—slow and gentle for pMDI and fast and strong for DPI—can be coached.
