Abstract
A nebuliser comprises means for determining the duration of a pulse of atomisation during inspiration, the determination means including means for measuring the tidal volume of a patient, timing means for measuring the duration of inspiration, means for storing estimates of the volume of a patient's upper airway, and means for calculating the duration of the pulse. The duration of the pulse is calculated on the basis of the tidal volume measured by the tidal volume measuring means, the duration of inspiration measured by the timing means, and the stored estimated volume of patient's upper airway from the storage means.
