Asthma Spacer - Benefits

Benefits

In order to properly use an inhaler without a spacer, one has to coordinate a certain number of actions in a set order (pressing down on the inhaler, breathing in deeply as soon as the medication is released, holding your breath, exhaling), and not all patients are able to master this sequence. Use of a spacer avoids such timing issues. Spacers slow down the speed of the aerosol coming from the inhaler, meaning that less of the asthma drug impacts on the back of the mouth and somewhat more may get into the lungs. Because of this, less medication is needed for an effective dose to reach the lungs, and there are fewer side effects from corticosteroid residue in the mouth.

Valves on a spacer (which technically makes it a holding chamber) cause the patient to inhale the contents of the spacer, but exhalation goes out into the air. The problem of co-ordinating an inspiration with a press of an inhaler is avoided, making use easier for children under five and the elderly. It also makes asthma medication easier to deliver during an attack. For this reason, many advise use of spacer.
