title: Clinical trial of two inhalation techniques for pressurized aerosols.
abstract: The clinical effects of a bronchodilator, terbutaline sulphate, were compared after administration in the beginning of the inhalation by means of a standard inhaler and administration by actuating 2 seconds before starting the inhalation by means of an inhaler furnished with a 32 X 100 mm tube. No differences could be seen in the parameters measured-forced vital capacity (FVC), 1-second forced expiratory volume (FEV1), forced mid-expiratory flow (FMF), and oscillatory resistance (Ros). The results indicate that when attaching a tube to the standard inhaler co-ordination of inhalation and actuation of the aerosol is not of vital importance.
