What does mandatory minute ventilation (MMV) primarily assist with?

• A. It helps maintain constant pressure
• B. It aids in weaning patients from the ventilator
• C. It delivers maximum pressure during ventilation
• D. It stabilizes tidal volumes

Answer: (B)

Mandatory minute ventilation (MMV) is primarily designed to assist patients in maintaining adequate ventilation by ensuring a minimum minute ventilation level. This mode is beneficial during the weaning process from mechanical ventilation because it allows the patient to take spontaneous breaths while also guaranteeing that a predetermined minimum minute ventilation is achieved. If the patient does not reach this minimum threshold through spontaneous breathing efforts, the ventilator will deliver additional breaths to meet the required minute volume. This supportive feature not only eases the transition from mechanical support to independent breathing but also helps prevent respiratory muscle fatigue and maintains adequate gas exchange. The intent behind MMV is to enhance patient comfort and safety during weaning by providing necessary assistance rather than solely focusing on pressure control or tidal volume stabilization. This is essential when considering patients who may be weak or unable to sustain adequate ventilation through spontaneous efforts alone.
