Abstract

Drugs can be delivered as aerosols from three types of inhalation device, namely the nebuliser, the metered dose inhaler and the dry powder inhaler. Nebulisers are the most versatile of these devices. Aerosol output, droplet size and nebulisation time have been measured for four brands of jet nebuliser using 7% saline solution and operated at gas flow rates between 6 and 12 1/min. The output of NaCl in droplets less than 5 mu m diameter, taking into account the increase in saline concentration during nebulisation, varied over a five-fold range according to the type of nebuliser, the initial volume fill and the gas flow rate.
