Cheers
Forced Expiratory Time (FET) and Forced Expiratory Volume (FEV) are two different things.

Forced Expiratory Volume in One Second (FEV1)

The volume of air exhaled during the first second of a forced expiratory maneuver. The FEV1 is useful for detecting obstructive diseases since a person with obstructed airways will not be able to exhale as much air in the first second as a person with normal lungs. The FEV1 may also be low if the person has severe restrictive disease.

Forced Expiratory Time (FET):

The time taken to expire a given volume during measurement of forced vital capacity.

Hope this would be helpful.
