Capital Health Care tests FEV1 & FEV6
FEV1 is the forced expiratory volume or the amount we can blow out in one second after filling our lungs. They look at how close this is to what would be predicted as "normal" for someone of your height, age, etc. Then they give the results as a percentage. So if you do a good strong blow and have healthy lungs you may reach 80% of what would have been predicted (which would be good). You may only manage to blow out 15% or less (which would be very poor). So your FEV1 % is a marker for the degree of obstruction in your lungs.
Generally this is read as:
FEV1 80% of predicted = normal
FEV1 60% to 79% of predicted = mild obstruction
FEV1 40% to 59% of predicted = moderate obstruction
FEV1 less than 40% of predicted = severe obstruction
