Web21 mrt. 2024 · MMEF, widely known as FEF 25-75, corresponds to the mean forced expiratory flow between 25 and 75% of the forced vital capacity (FVC). Its use is based on the hypothesis that the mid-late portion of the FVC reflects the airflow through the small airways, which are prone to expiratory collapse due to their lack of cartilaginous support.
