What does Mandatory Minute Ventilation (MMV) ensure?

• A. It provides completely spontaneous breaths only
• B. It guarantees a minimum minute ventilation
• C. It functions only in pressure support mode
• D. It is used exclusively for patients with chronic obstructive pulmonary disease

Answer: (B)

Mandatory Minute Ventilation (MMV) is a mode of mechanical ventilation designed to ensure that a patient receives a specified minimum level of minute ventilation, regardless of their spontaneous breathing efforts. This is crucial for patients who may be unable to maintain adequate ventilation on their own due to respiratory insufficiency or other medical conditions. By guaranteeing a minimum minute ventilation, MMV helps to prevent hypoventilation and ensures that the patient's carbon dioxide levels are managed effectively. The mode allows for both mandatory breaths, in which the ventilator assists or controls the breath, and spontaneous breaths, providing flexibility in patient-ventilator interaction. This ensures that even if a patient is not able to initiate breaths consistently, the ventilator will provide adequate support. In contrast, the other options describe scenarios that do not align with the fundamental purpose of MMV, such as focusing solely on spontaneous breaths or being limited to specific patient populations or mechanical ventilation modes.
