The primary function of a ventilator during anesthesia is to support the patient's breathing. When a patient is under anesthesia, their natural ability to breathe may be impaired due to the effects of anesthetic agents on the respiratory system. A ventilator takes over the work of breathing by delivering a controlled mixture of oxygen and anesthetic gases to the patient's lungs and removing carbon dioxide. This mechanical ventilation ensures that the patient maintains adequate oxygenation and ventilation throughout the surgical procedure, which is critical for patient safety and effective anesthesia management.

While other options pertain to important aspects of patient care, they do not align with the specific role of a ventilator. Delivering medication is typically the responsibility of anesthesia delivery systems, monitoring blood pressure is performed by vital sign monitors, and fluid delivery is managed through intravenous lines. The ventilator's primary role centers solely on maintaining respiratory support, making it essential in the anesthetic management of patients undergoing surgery.
