Metered-Dose Inhaler Used with an Aerochamber
For Teenagers
A metered-dose inhaler (MDI) is a canister of medicine
that releases a medicated mist. The Aerochamber is a spacer
device that can be used with a metered-dose inhaler. The
Aerochamber helps you inhale more medicine into your lungs.
To attach the MDI to the Aerochamber:
- Remove the caps from the Aerochamber and metered-dose
inhaler.
- 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:
- Breathe all the air out of your lungs. Then put the
Aerochamber into your mouth between your teeth. Make a
tight seal around the mouthpiece with your lips.
- Press the MDI down once to release a spray of medicine.
The medicine will be trapped in the Aerochamber.
- Breathe in slowly and deeply.
- Hold your breath for 5 to 10 seconds. (This gives the
medicine time to reach the airways.)
- Take the Aerochamber out of your mouth. Breathe out
slowly.
- Take a few normal breaths and then repeat steps 1
through 5 for another inhalation (puff) if required.
Take the number of puffs prescribed by your health care
provider.
Cleaning the MDI and Aerochamber
Wash the Aerochamber and the plastic case for the
metered-dose inhaler once a week with soapy tap water.
Rinse and dry them thoroughly.
With time, the flap valve may harden and start to curl,
making the chamber inefficient. You will then need to get a
new Aerochamber.
