• We’re using Fractional exhaled Nitric Oxide (FeNO) - a harmless gas that we use as a marker for airway health   

• Proposed study design (25 healthy children without asthma or other respiratory conditions) 

  • Ideal participants children 2-18 years of age 

  • Able to sign up for 8 week study (Summer 2022)

​

​

Home visit: Each week (on the same day of the week) we would come by participant's home and take FeNO airway measurement (time ~15 minutes total)
