Fig. 1From: Instant velocity and consistency of emitted cloud change by the different levels of canister filling with Metered Dose Inhalers (MDIs), but not with Soft Mist Inhalers (SMIs): a bench studyColorimetric difference in the turbulence pattern obtained with MDI A (a) and SMI (b). The spots of bright colours indicates the sites of highest turbulence during the cloud emission, and their distribution. Dark colours indicate the absence of turbulence and the homogeneity of cloud emission. The variability of the red diagram trend indicates the corresponding dynamic stability or instability during all emission phasesBack to article page
