The FEV1/FVC ratio is almost universally used to determine the presence or absence of airway obstruction. There are several different threshold values for this, however. Lower Limit of Normal (LLN): The ATS/ERS statement on interpretation recommends the use of the Lower Limit of Normal (LLN) for the FEV1/FVC ratio as well as the FVC and FEV1.

FeV1/FVC ratio is important as this ratio is decreased in obstructive lung diseases. It is expressed as percentage. Forced expiratory volume is the maximum amount of air you can forcefully exhale in one second.It is used to describe the degree of airway obstruction caused by asthma in a routine test called spirometry or pulmonary function testing, using an instrument called a spirometer.
