Reference Entry
A definition of the term "spacer" is presented. It refers to a hollow tube that improves the delivery of inhaled aerosols, such as beta agonists, steroids, and other antiasthmatic drugs. They improve the performance of anti-asthmatic drugs because without them, a large quantity of inhaled medications end up in the mouth or on the palate.
