What does controlled ventilation primarily consist of?

• A. Assisted and spontaneous breaths
• B. Controlled breaths only
• C. Only spontaneous breaths
• D. A combination of all breath types

Answer: (B)

Controlled ventilation primarily consists of controlled breaths only. This approach is characterized by the ventilator delivering a set breath rate and volume regardless of the patient's effort. In controlled ventilation, the patient does not initiate breaths; instead, the ventilator is responsible for all the ventilatory support. This mode is typically used for patients who are unable to breathe adequately on their own, ensuring they receive sufficient ventilation to meet their body's needs. The distinction is crucial in understanding various ventilation modes. For instance, assisted breaths involve the patient initiating a breath but requiring the ventilator to deliver additional support, which is not the case in pure controlled ventilation. Similarly, spontaneous breaths are solely patient-driven and do not rely on the ventilator for assistance, thus contrasting with the core concept of controlled ventilation. The other answer options present scenarios that blend controlled and spontaneous modes, which do not accurately define controlled ventilation itself.
