Fig. 2From: Aerosol delivery through high flow nasal cannula compared to biphasic positive airway pressure, at two different pressure: an in-vitro studySchematic diagram showing the measurement of the total inhalable dose using high flow nasal cannula system at oxygen flow 5 L min−1 [19]. SOLO vibrating mesh nebulizer was connected to the HFNC system upstream just before the humidifier which was connected to the nasal cannula. An electrostatic filter pad (inhalation filter) enclosed in a filter holder was then connected to the nasal cannula to collect the TID then was connected to a breathing simulator modelBack to article page
