Measurements > Spirometry displays your data as a breakdown of the ration ratio of POST FEV1/FVC.
FEV1 is the forced expired volume in one second
FVC is the forced vital capacity
FEV1/FVC provides an index of airflow limitation; a value < 0.7 indicates limitation
The breakdown is shown as
- POST FEV1/FVC < 0.07
- POST FEV1/FVC >= 0.07
- Not recorded
