[A technical inhalation test variant for improving the effectiveness of the use of dose aerosols].
We compared the airway responsiveness to beta 2-agonist aerosol inhalation with two breathing techniques for bronchodilator testing in 25 patients with COPD. Open breathing technique showed better results than closed breathing technique. Causes for these results like optimization of volume and flow conditions for aerosol deposition are discussed.
