Metered-Dose Inhaler Used with an Aerochamber
The Aerochamber is a device used to extend the space between
the mouth and the metered-dose inhaler (MDI) used with some
asthma medications. The spacer helps a child get more
medication into his or her lungs.
To attach the MDI to the Aerochamber:
- Remove the caps from the Aerochamber and metered-dose
- Shake the metered-dose inhaler vigorously.
- Insert the mouthpiece of the inhaler into the rubber-
sealed end of the Aerochamber.
To use the MDI with the Aerochamber:
- Put the Aerochamber into the mouth between the teeth and
seal the lips.
- Depress the metered-dose inhaler once. The medication
will then be trapped in the spacer.
- Breathe in slowly.
- Hold the breath for 5 to 10 seconds.
- Breathe out slowly.
- Repeat breathing in and out twice more.
Cleaning the MDI and Aerochamber
Wash the metered-dose inhaler plastic case and aerochamber
once a week with soapy tap water and dry thoroughly. With
time, the flap valve may harden and start to curl, making
the chamber inefficient.
