Normal Spirometry Values of FeV are more important for assessing the lung function. Normal person can exhale 83 to 85%of FVC in 1 second (so FeV1 is 83 to 85%), 93% in 2 seconds (FeV2 is 93%) and 97% in 3 seconds (FeY3 is 97%). Lung Volume Reference Values for Women and Men 65 to 85 Years of Age Francisco Garcia-Rio 1, Ali Dorgham , Jose´ M.
