ANS: C
A terminal flow control is provided for minor leak compensation on the PR-1 or PR-2. Negative end-expiratory pressure is a negative pressure that can be applied to the end of expiration and does not have anything to do with leak compensation. The diluter regulator is an adjustable re-ducing valve that regulates the gas pressure delivered to the patient. The flow control adjusts the velocity of the gas flowing to the patient.
