Metered-Dose Inhaler with AeroChamber

A metered-dose inhaler (MDI) is a piece of equipment that enables your child to breathe or inhale a fixed dose of his/her medication.

When your child uses a metered-dose inhaler, the medication works quickly, and it goes directly to his/her lungs. A spacer is always used with an MDI to maximize the amount of medication inhaled.

  1. Metered-Dose Inhaler withAeroChamberTo use this type of spacer, your child must be able to inhale through the mouth at the right time. Usually this is someone over 6 years of age who is able to follow instructions with demonstration. If your child is unable to use a mouthpiece, see how to use an MDI with a mask.
  2. Check the expiration date on the device before using it. Discard it if it has expired and get a new prescription.  
  3. Remove the plastic protective cap from the MDI and from the spacer.  
  4. Insert the MDI of medicine into the plastic holder on the rubber end of the AeroChamber. 
  5. Shake the AeroChamber and MDI.
  6. Have your child breathe out as much of his/her air as he/she can.
  7. Have your child place the spacer mouthpiece into his/her mouth, gripping it gently with lips and teeth.
  8. Spray one puff from the metered-dose inhaler into the AeroChamber.
  9. Have your child breathe in slowly and deeply. If you hear a whistle, then have your child breathe in slower.
  10. Have your child hold his/her breath, and count to 10.
  11. Take the mouthpiece out of your child's mouth and have your child gently breathe out through pursed lips (similar to blowing out a candle).
  12. Rest, wait one minute and repeat according to the doctor's direction.
  13. At least once a week, remove the back piece of the AeroChamber only. Soak the back piece and chamber for 15 minutes in lukewarm water and liquid detergent. Rinse with clean water and allow it to air dry in the upright position. 

Some metered-dose inhalers will still appear to be working even after the medication is gone, which can be dangerous.

  • If your child uses his/her inhaler only as needed, you can determine the amount of medication inside by removing the canister from the plastic sleeve and shaking it gently with your index finger on the flat end. Obtain a refill when a small amount is remaining
  • If your child uses his/her inhaler at least once a day, you will need to get a refill from the pharmacy about once a month.
