Therapeutic gas, such as NO, is delivered to a patient in accurately controlled amounts by a system that uses a closed loop feedback system in which the amount of therapeutic gas delivered is a precise fraction of the total gas delivered to the patient. Ratiometric feedback is used in the control loop.
