The abbreviation MEP stands for which ventilator parameter?

The abbreviation MEP stands for which ventilator parameter?

• A. Mean Expiratory Pressure
• B. Maximum Expiratory Pressure
• C. Minimal Expiratory Pressure
• D. Mean End-Pressure

Answer: (B)

MEP refers to the highest pressure reached during the expiratory phase of a breath—Maximum Expiratory Pressure. This term highlights the peak expiratory effort, which is related to how strongly air can be expelled and how much airway resistance is present. It differs from peak inspiratory pressure, which occurs during inhalation. The other terms aren’t standard ventilator parameters: mean expiratory pressure would imply an average over expiration, minimal expiratory pressure isn’t a typical metric, and mean end-pressure isn’t used in this context (the end-expiratory pressure is typically PEEP).
