Metered Dose Inhalers for Asthma

How Does my Child Use a Spacer Device?

Directions for using the metered dose inhaler with a spacer chamber and a device like a mask are given below. Read these instructions before using the device. Your asthma care team will also teach you and your child how to use these devices.

To use the MDI and spacer (with or without a spacer device ):

  1. Remove the caps from the MDI and spacer chamber( add spacer device if needed).
  2. Shake the canister well.
  3. Insert the MDI into the back end of the spacer chamber.
  4. If there is a spacer device such as a mask, place it over your child's nose and mouth, making sure there is a good seal. If there is just a mouth piece, the tip should go between the teeth and lips wrapped tightly around to make a good seal.
  5. Press down firmly on the canister to release one puff of the medication into the spacer chamber.
  6. Hold the mask firmly in place while your child takes at least six breaths. If your child is using a spacer chamber with mouth piece, after inhaling the medication, he should hold his breath for 5-10 seconds then breathe out slowly.
  7. Wait one minute.
  8. Repeat steps two through seven for each puff of medication ordered.
  9. When treatment is complete, remove the MDI from the space chamber.
  10. If using this device with an MDI that contains a steroid, wipe your child's face with soap and water after use to remove any medication. If possible, also rinse your child's mouth with water.

There are specialized valved-holding spacers that have a one-way valve that allows the drug to be inhaled but also helps holds the medication in the chamber during exhalation . These devices can be fitted with a mouthpiece or a facemask to be used in infants and young children.

How Do I Care for a Metered Dose Inhaler With a Spacer ?

Clean the spacer chamber every other day. If you are not using it often, you may only need to clean it once a week. Let it air dry, and store it in a clean, dry place when you're not using it.
