Summary of the AS aerosol delivery characteristics for the WES device (n = 4) with 1 hour of operation. WES Device and Emitted Dose represent the mass of drug in micrograms remaining in the device flow pathway and emitted from the device, respectively. For the WES, AS device loss was greater than the emitted dose. Moreover, high coefficients of variation in both WES device deposition and emitted dose indicate highly variable performance.
| Mean AS mass (μg) | Coefficient of Variation (%) | Range (μg) | |
|---|---|---|---|
| WES Device | 11.80 | 106.0 | 0.90 – 25.2 |
| Emitted Dose | 15.05 | 109.1 | 0.71 – 29.9 |
| Total Recovered Dose | 26.85 | 107.4 | 1.87 – 55.1 |
