MDI, Spacer & 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 four sizes: infant, toddler, youth and adult. Make sure the mask covers the nose and mouth snuggly, but not so big that it covers the eyes
- At age 4 years*, children should switch from a spacer with a mask to a spacer with a mouthpiece. Up to 66% of the medicine can be lost in the nose when using a spacer with a mask
- Aerochambers are one of the more common spacer devices and different sizes are different colors: Infant (Orange), Toddler (Yellow), Youth (Purple) and Adult (Blue)
