Different forms of synchronized aerosol delivery during a breathing waveform as described by Denyer et al.(82) Light gray indicates aerosol that is generated during inhalation and ideally reaches the lungs. Darker gray indicates the proportion of aerosol that is generated during exhalation and has little chance of reaching the lungs. Both the flow rate and delivery duration of the delivered aerosol varies with synchronization method.
