MEP stands for what?

MEP stands for what?

• A. Maximum expiratory potential
• B. Minimum expiratory pressure
• C. Mega expiratory pressure
• D. Maximum expiratory pressure

Answer: (D)

Understanding expiratory strength terminology used in respiratory testing helps you see why this term is used. MEP stands for Maximum Expiratory Pressure—the highest pressure a person can generate during a maximal forced exhalation against an occluded airway. It’s measured with a pressure manometer while the patient exhales forcefully into a closed system, and it reflects expiratory muscle strength and airway function. Clinically, a higher MEP indicates stronger expiratory muscles and better ability to clear secretions or wean from ventilation, while a low MEP can suggest weakness or obstruction. The other options aren’t standard terms in this context, so they don’t describe the measurement used.
