Abstract:
1. A system for monitoring arterial gas concentrations of a patient receiving both mechanical ventilation support and percutaneous oxygenation support, the system comprising: a ventilator for providing mechanical ventilation support to a patient; a first flow sensor associated with the ventilator for determining a gas flow provided to the patient by the ventilator; a first gas analyzer associated with the ventilator for determining a gas concentration provided to the patient by the ventilator; a percutaneous oxygenator for providing medical gases to a venous system of the patient via a catheter, wherein the catheter also removes gases from the venous system of the patient; a second flow sensor associated with the gases removed from the patient via the catheter for determining a gas flow out of the catheter; a second gas analyzer associated with the gases removed from the patient via the catheter for determining gas concentrations associated with the gas removed from the patient via the catheter; and a CPU comprising an algorithm that computes a blood gas concentration of the patient; wherein data from the ventilator, percutaneous oxygenator, first and second flow sensors, and first and second gas analyzers is provided to the CPU and the CPU applies the data to algorithms to compute arterial gas concentrations of the patient.
