Expected incentive spirometry values
WebIf 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.) WebSep 7, 2024 · Normal results for a spirometry test vary based on a number of factors. Specifically, these include a patient’s: age, height, race and sex. FVC Normal and Abnormal Ranges Normal Value for FVC: Healthy: 80% or above Abnormal Values for FVC: Mild: 70 to 79% Moderate: 60 to 69% Severe: <60% FEV1 Normal and Abnormal Ranges
