What is the primary goal of controlled ventilation?

• A. To allow the patient complete control of breathing
• B. To ensure all breaths are mechanical
• C. To mix assisted and controlled breaths
• D. To promote spontaneous breathing patterns

Answer: (B)

The primary goal of controlled ventilation is to ensure that all breaths delivered to the patient are mechanical. This mode is typically employed in situations where the patient's own breathing is inadequate to meet their physiological needs, such as in severe respiratory failure or during surgery. By providing mechanical breaths, the ventilator can maintain adequate tidal volumes and oxygenation regardless of the patient's respiratory drive. In controlled ventilation, the ventilator takes over the responsibility of breathing entirely, ensuring a consistent and reliable breath rate, volume, and pressure, which is crucial for patients unable to maintain adequate ventilation independently. This method is particularly important in managing patients who are unable to breathe on their own due to sedation or respiratory compromise. Other options reflect different aspects of ventilation strategies, but they do not align with the primary goal of controlled ventilation. Allowing patients complete control of breathing is characteristic of spontaneous modes, mixing assisted and controlled breaths pertains to modes like assist-control, while promoting spontaneous breathing is not the focus when controlled ventilation is implemented.
