There is an increasing awareness of the importance of reliable aerosol delivery, with emphasis on the dose delivered to the lungs, optimal clinical control, cost-effectiveness, and safety in children. Dose prescription should relate to the expected lung dose rather than the factory-dispensed dose, as at present. The device determines the lung dose. ⋯ Finally, a nonelectrostatic, tower-shaped spacer provides a stable aerosol, which remains airborne for a prolonged period. The spacer is equipped with a face mask that prevents nasal breathing. Such features should improve our ability to treat young children with inhaled drug aerosols.
