MDI with Mask and Spacer image

MDI, Spacer and Mask (under 4 years)

  • Using an inhaler without a spacer is NOT recommended.  More medicine is delivered to the lungs using a spacer
  • Masks come in two sizes, infant and child.  Make sure the mask covers the nose and mouth snuggly
  • At age 4-6 years, children should switch from a spacer with mask to a spacer with mouthpiece. Up to 66% of the medicine can be lost in the nose when using a spacer with a mask
