Term Description
Peak Expiratory Flow Rate (PEFR) The maximum expiratory flow rate achieved which occurs very early in the forced expiratory process.
Forced Expiratory Volume in 1 second (FEV1) The volume is expired in the first second of maximal expiration after a maximal inspiration.
Vital Capacity (VC) The maximum volume of air that can be exhaled or inspired during either a formed (FVC) or a slow (VC) process.
Forced Vital Capacity (FVC) The maximum volume of air that can be exhaled or inspired during a formed FVC process.
Tip:
The FER value is automatically calculated by tool.
FEV1/FVC/ Represents the FEV1 as a percentage of the FVC (whichever volume is larger) and gives a clinically useful index of airflow limitation.
FEF25-75% Shows the average expired flow over the middle half of the FVC process and is regarded as a more sensitive measure of small airways narrowing than FEV1. But, FEF25-75% has a wide range of normality, is less reproducible than FEV1, and is difficult to interpret if the VC (or FVC) is reduced or increased.
