System and method for controlling blood oxygenation

Abstract

A system 100 for controlling blood oxygenation in a patient. The system comprises an oxygenator 200 configured to receive blood from the patient and to expose the blood to an amount 124 122 of oxygen as the blood passes through the oxygenator 200 to produce oxygenated blood. The system 100 further comprises a sensor 110 positioned downstream of the oxygenator 200 and configured to 120 measure a saturation of oxygen present in the oxygenated blood. The system 100 further comprises a controller 150. The controller 150 is configured to receive the measured saturation of oxygen from the sensor 110, calculate a difference between a target saturation of oxygen and the measured saturation of oxygen, and adjust the amount of oxygen to which the blood is exposed in the oxygenator 200 to reduce the difference.
