Maximum mid-expiratory flow rate

Deutsch: Maximaler mittlerer exspiratorischer Fluss / Español: Flujo espiratorio máximo medio / Português: Fluxo máximo de meio expiratório / Français: Débit de pointe expiratoire maximal / Italiano: Massimo flusso espiratorio medio /

A Maximum mid-expiratory flow rate (MMFR or MMEF) is Synonymous with FEF25-75 %.

In the context of the environment, "maximum mid-expiratory flow rate" (MMEF) is a measure of the maximum flow rate of air that a person can exhale during the middle portion of a forced expiration. MMEF is often used as a measure of lung function and can be used to assess conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory disorders.

MMEF is typically measured using a device called a peak flow meter, which is a handheld device that measures the maximum flow rate of air that a person can exhale. To use a peak flow meter, a person takes a deep breath and then exhales as hard and fast as possible into the device. The peak flow meter then measures the maximum flow rate of air that is exhaled and displays the result on a scale.

MMEF can be affected by a variety of factors, including age, gender, and overall health. It is typically used as part of a comprehensive assessment of lung function and can help to diagnose and monitor respiratory conditions.
