FEV Graph

FEV: Norm, Obstructive, Restrictive
- FEV1, which is the amount of air forcibly exhaled in the first second, is a good measure of airflow. When expressed as a % of the forced VC (FVC), it can be used to diagnose obstructive diseases such as COPD and asthma. Normal FEV1% > 80.
- Restrictive lung disease patients demonstrate a normal or increased FEV1%.
- FEF25-75% is another way to estimate flow rate and correlates with the FEV1% and the flow volume loop to be discussed next
