In brief: FEV1
An expiratory volume is usually how much air your expell from your lungs in a unit of time (fev1 = expiratory volume in 1 second).
There are predicted normals (based on sex, height, weight and race). A normal number or a number greater than 70 perent of your predicted normal is ideal.
