Abstract
A nebuliser having elements for determining the duration of a pulse of atomisation during inspiration, including elements for measuring the tidal volume of a patient timing elements for measuring the duration of inspiration, elements for storing estimates of the volume of a patient's upper airway, and elements 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 elements; the duration of inspiration measured by the timing elements, and the stored estimated volume of patient's upper airway from the storage elements.
