Abstract
A control system controlling blood gas values in blood processed by an oxygenator, wherein the oxygenator generates arterial blood by exposing venous blood to oxygen from an oxygenation gas supply, comprises a monitoring arrangement to determine a level of the blood gas values in the arterial blood and a controller that is responsive to the monitoring arrangement and configured to control parameters of the oxygenation gas supply to the oxygenator. This allows the blood gas values to be adjusted toward a pre-determined level.
Claims28
A control system controlling at least one blood gas value in blood processed by an oxygenator of an extracorporeal perfusion system, wherein the oxygenator is configured to generate arterial blood by exposing venous blood to oxygen from an oxygenation gas supply, the control system comprising:
- a monitoring arrangement to determine a level of the at least one blood gas value in the arterial blood, and
- a controller responsive to the monitoring arrangement, the controller configured to control parameters of the oxygenation gas supply to the oxygenator, to adjust at least one of the blood gas values toward a pre-determined level.

A method of controlling at least one blood gas value in blood processed by an oxygenator of an extracorporeal perfusion system, wherein the oxygenator is configured to generate arterial blood by exposing venous blood to oxygen from an oxygenation gas supply, the method comprising the steps of:
- determining a level of each of the at least one blood gas value in the arterial blood, and
- controlling, in response to the level, parameters of the oxygenation gas supply to the oxygenator, to adjust at least one of the blood gas values toward a pre-determined level.
