Abstract
An arrangement for delivering a drug aerosol comprises a sensor (3) which detects turbulent air flow during inhalation and causes the nebulizer (8,9,10,11,12,13) to generate the aerosol only during the inhalation phase of the breathing cycle. Airflow is diverted from the sensor during exhalation.
