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:

  1. Remove the caps from the Aerochamber and metered-dose inhaler.

  2. Shake the metered-dose inhaler vigorously.

  3. Insert the mouthpiece of the inhaler into the rubber- sealed end of the Aerochamber.

To use the MDI with the Aerochamber:

  1. Put the Aerochamber into the mouth between the teeth and seal the lips.

  2. Depress the metered-dose inhaler once. The medication will then be trapped in the spacer.

  3. Breathe in slowly.

  4. Hold the breath for 5 to 10 seconds.

  5. Breathe out slowly.

  6. 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.
