Spacers and Valved-Holding Chambers

Valved Holding Chamber If you don't use your inhaler the right way, much of the medicine may end up on your tongue, on the back of your throat, or in the air. A spacer or valved-holding chamber can help keep this from happening.

A spacer or valved-holding chamber attaches to the inhaler. It holds the medicine in the chamber long enough for you to inhale the medicine in one or two slow, deep breaths. A spacer will help keep you from coughing when using an inhaler.

A spacer will also help prevent you from getting a yeast infection in your mouth (known as thrush) when taking inhaled steroid medicines.

Using a spacer or holding chamber with a mouthpiece is best, but if a young child or adult is unable to use one, a face mask works well.

How to Use a Metered Dose Inhaler with a Valved-Holding Chamber or Spacer

To use a spacer or valved-holding chamber, first read the instructions that came with it, since there are many types available. Use the general instructions below to help you get the most from your MDI.

1) Remove cap from metered dose inhaler (MDI).

MDI with face mask

For children who are not able to use a mouthpiece (under age 4 – depends on child), a facemask can be used with the MDI.

  • Shake the inhaler and prime it (if needed), then insert into the back of the chamber. Have the child sit on an adult's lap, make sure there are no small objects inside the chamber, and gently place the mask over the child’s mouth and nose (the child will be able to breath normally).
  • Pump the inhaler once and hold the mask in place as the child breaths in 6 times.
  • If more puffs of medicine have been prescribed, repeat these steps.
  • The child has gotten the medicine if his/her chest moved in and out for 6 breaths or a hand, placed the child's belly, moved up and down 6 times.
Hand wash the chamber with face mask once a week with warm water and dishwashing soap. Rinse gently with warm water and let air dry (do not use a towel). Replace if chamber gets cracked or broken.
