Fig. 4From: Aerosol drug delivery to the lungs during nasal high flow therapy: an in vitro studyThe emission efficiency of Man+Leu at different dispersion flow rates (DFR). The powder emission from the capsule was measured after 4, 8 and 16 s. The loaded dose in each experiment was 40 ± 4 mg. The nasal cannula-size was large. Each value represents the mean ± SEM (n = 3)Back to article page
