If the FVC and the FEV1 are within 80% of the reference value, the results are considered normal. The normal value for the FEV1/FVC ratio is 70% (and 65% in persons older than age 65). When compared to the reference value, a lower measured value corresponds to a more severe lung abnormality. (See table below.)

The most common symptoms are dyspnea or breathlessness, cough and sputum production. The FEV1/FVC ratio is almost universally used to determine the presence or absence of airway obstruction.

Search strategy We searched PubMed, Scopus and Web of Science (ISI) databases for population-based studies published be- The ratio FEV1/FVC is between 70% and 80% in normal adults; a value less than 70% indicates airflow limitation and the possibility of COPD. FEV1 is influenced by the age, sex, height, and ethnicity, and is best considered as a percentage of the predicted normal value.
