title: A comparison of "closed" and "open" mouth techniques of inhalation of a salbutamol metered-dose inhaler.
abstract: To compare two techniques of inhalation of a salbutamol metered-dose inhaler--"closed" mouth (keeping the actuator between the lips) and "open" mouth (placing the actuator a few centimeters in front of the open mouth)--50 asthmatics were tested with both methods. Twenty-seven patients completed the study. The baseline FEV1 on the 2 test days was similar. Inhalation of salbutamol by both techniques resulted in a significant and similar degree of bronchodilatation. The majority of patients preferred the closed-mouth technique.
