Peak flowmeter and spirometer mouthpieces as expansion chambers for metered dose aerosols

Ann Allergy. 1982 May;48(5):272-4.

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.
