<p>An aerosol delivery system (1) has a nebulizer (2) and a humidifier (7) providing a gas flow to the nebulizer. A controller varies humidity level of the gas flow to the nebulizer (2) so that if the nebulizer is not operating it has about 100% humidity and it is operating the value is less to allow for the humidification effect of the nebulizer. The control may be achieved by dynamically varying proportions of flow through a dry branch (10, 11) and a humidification branch (8, 7).</p> |
