Ventilator bellows are designed to deliver which of the following?

Explanation:
Ventilator bellows are the mechanism that deliver the amount of gas the patient is set to receive each breath—the tidal volume. The machine’s electronics control the timing and how much the bellows expand to push a precise volume into the patient, so the prescribed tidal volume is delivered consistently. FiO2 control, CO2 absorption, and waste gas scavenging are served by other parts of the anesthesia system: the gas blender sets the oxygen fraction, the CO2 absorber removes carbon dioxide from the circle, and the scavenging system handles waste gases. So the bellows’ primary role is to deliver the set tidal volume.
