Hello

FEF 25-75%

Forced expiratory flow between 25-75%

Average expiratory flow rate at the middle part of forced expiration. It is a more sensitive indication of what is happening in the middle/lower airways, but is not as reproducible as FEV1. Normal in restrictive disease.

Information from :

patient.co.uk/doctor/Spirom...

You can check other abbreviations from this page also, scroll down below the calculator.
