[A comparison of two delivery methods on the bronchodilator effects of beta 2-stimulant].

: The airway response to a bronchodilator, salbutamol delivered by a new handy ultrasonic nebulizer and the compressed air nebulizer was studied in a blind manner. Patients by the ultrasonic nebulizer had better percent increase in FVC and FEV1 significantly and in other parameters showed a tendency to being better than those by the compressed air nebulizer. These results suggest that this ultrasonic nebulizer may be more useful than the compressed air nebulizer as inhalation therapy for bronchial asthma. This ultrasonic nebulizer has several advantages over the compressed air nebulizer. This nebulizer is compact size, light weight and has dry batteries as power source, making it more convenient for travel and use at workplace.
