Abstract
A system and method for monitoring the arterial gas concentrations of a patient receiving percutaneous oxygenator support. The system comprises a percutaneous oxygenator for providing medical gases to the venous system of the patient via a catheter. Gases are also removed from the venous system via a catheter. The concentrations and flow rates of the gases provided and removed from the patient are monitored. A CPU analyzes the concentration and flow rate information to compute the arterial gas concentration of the patient.
