Abstract: Device for determination of a CO2 partial pressure value on a blood side of an oxygenator having an oxygenator with a blood side, a gas side and a semipermeable membrane, wherein the membrane separates the blood side from the gas side, the gas side has an inlet and an outlet and, during operation of the oxygenator, a gas flow flows into the inlet to the outlet at a flow rate. The device also has a first sensor configured to measure CO2 partial pressure values of the gas side and a control unit configured to process the measured CO2 partial pressure values of the gas side and to determine a CO2 partial pressure value on the blood side based on the measured CO2 partial pressure values of the gas side. The control unit determines the CO2 partial pressure value on the blood side during operation of the oxygenator.

Abstract: Electrode assembly patches configured for conductance and admittance measurements, and methods of manufacturing same. The present technology provides designs and manufacturing methods that may enable a conductance or admittance electrode assembly patches to be flexible, low-profile, and easily applied to an intravascular blood pump or other device, such that there may be little or no change to the device's overall diameter, profile, and functionality.
