Abstract
Expansion chambers increase effective bronchial delivery of metered dose aerosol asthma medications. A subjective comparison suggests that peak flowmeter and spirometer mouthpiece tubes function effectively as expansion chambers, though less so than a prototype commercial device. Use of mouthpieces as expansion chambers is recommended until improved devices become available.
