Asthma in children: Helping a child use a metered-dose inhaler and mask spacer
What is a metered-dose inhaler? What is a mask spacer?
A metered-dose inhaler (MDI) is a handheld device that delivers a measured dose of medicine directly to the lungs. The medicine is usually in an aerosol form.
Using a spacer with an MDI is the most efficient way to get the most medicine to your child's lungs. A spacer works like a holding area for the medicine before your child breathes in. Using a spacer with the MDI may improve the delivery of the medicine and may help your child if he or she has problems with releasing the medicine and inhaling at the same time. A spacer should always be used with inhaled corticosteroids to avoid side effects.
A mask spacer is a spacer with a face mask at the end of the spacer. This is put over your child's mouth and nose. Mask spacers are used for young children who cannot use a spacer with a mouthpiece. They are usually needed for children from infancy through about age 5. But many children about age 2 and older do not like the mask. Encourage them to learn to use a standard spacer if they are willing to try it. Older children and adults who have problems using an MDI and spacer can also use a mask spacer.

Using an MDI with a mask spacer may make it easier for your child to get the medicine to his or her lungs.
