For any spirometry test that has Pre and Post efforts, significance of the BD response will be

SpiroPerfect will deem the Bronchodilator response to be significant if either FVC or FEV1:
 Show an increase from Pre to Post of 12% or more, AND
 Have an absolute increase from Pre to Post of 200 mL or more.
