[Application of the ultrasonic aerosol apparatus "TuR" USI50 for the test of the bronchial reactivity--comparative studies with "TuR" USI3 (author's transl)].

By comparative studies with the ultrasonic aerosol apparatus "TuR" USI3 and "TuR" USI50 was shown that their applicability for tests of the bronchial reactivity leads to corresponding test results. Based on long experiences with the ultrasonic aerosol method the USI50 apparatus may recommended also for use of the acetylcholine test (0.01% solution) in clinics and ambulances. Detailed references are given for use of the application technique to guarantee that uniform conditions of investigation are present.
