    Abstract:
    The purpose of this paper, after a brief review of the main features of bronchoprovocation challenges, was to determine whether the administration of an ultrasonic mist of distilled water can influence the bronchial tone of normal subjects and patients affected by various respiratory disorders, in order to assess the effectiveness of this bronchoprovocation test in discriminating between patients. Of the 129 subjects tested 13 were classified as normal, 60 as extrinsic asthmatics, 21 as intrinsic asthmatics, 25 as allergic rhinitics and 37 as chronic bronchitics. Ultrasonic mist, was administered for 5 min and the bronchial response was evaluated in terms of difference between that after the mist minus baseline values of specific airways conductance. The data suggest that the bronchial challenge with ultrasonic mist, a safe, non-pharmacological and simple test, allows a good discrimination between asthma patients and those affected by other respiratory disorders.
