Doctors calculate the results of a spirometry test as a percentage of the “normal” value for someone of your height, age, sex, and race. For example, if your FEV1 is 80%, this means that you can exhale 80% of the amount of air that a person of your height, age, sex, and race with healthy lungs could exhale in 1 second.
