FEV1 is a measurement used to stage and diagnose lung diseases. It measures the amount of breath a person can exhale in one second. Find out more about how it works, what the results mean, and how For example, when FEV1 values make up less than 80% of the FVC, an obstructive lung disease is likely present. However, in restrictive lung diseases, both the FEV1 and FVC measurements decrease proportionally.

Find out more about how it works, what the results mean, and how For example, when FEV1 values make up less than 80% of the FVC, an obstructive lung disease is likely present. However, in restrictive lung diseases, both the FEV1 and FVC measurements decrease proportionally. To determine the FEV1 and FVC ratio, your doctor will divide your FEV1 into your FVC. The normal value for the FEV1/FVC ratio is above 0.75. Values lower than 0.70 are suggestive of airflow limitation with an obstructive pattern whilst in restrictive lung diseases, this ratio is normal or high.
