In a comparative trial of seven different spacer devices published in Thorax {1996,51:835-40} researchers found that whereas one device could deliver 124 Percent of the dose recovered using a metered dose inhaler alone, another may deliver as little as 21 Percent of the same drug.

Overall, large volume spacers performed appreciably better than the smaller spacers tested with sodium cromoglycate and salbutamol.

A valved chamber with exhalation ports is useful to prevent exhalation into the chamber and allow inhalation of drug remaining in the chamber after the first breath in.
