What is a key setting used in MMV for the volume control mode?

• A. Respiratory rate
• B. Pressure support level
• C. Tidal volume
• D. Inspiratory time

Answer: (C)

In volume control mode, which is a feature of MMV (Mandatory Minute Ventilation), the primary goal is to deliver a set tidal volume with each breath, ensuring that the patient receives a specific volume of air regardless of their own efforts. Setting the tidal volume directly influences the amount of air delivered to the patient with each mechanical breath, making it a fundamental parameter of this mode. Using tidal volume as a key setting ensures that the patient's ventilatory needs are met, helping to maintain adequate ventilation and prevent complications such as hypoventilation or hyperventilation. This method provides a predictable amount of gas exchange, which is crucial in managing patients with varying levels of respiratory drive or strength. Respiratory rate, pressure support level, and inspiratory time play roles in other modes of ventilation or in adjusting patient comfort and support, but they do not directly determine the volume delivered in volume control mode. Therefore, the focus on tidal volume is what makes it the correct answer in this context, as it is the primary factor that dictates the effectiveness of the volume control function within MMV.
