Abstract: The present model of utility is related to an extracorporeal circulation system used as an extracorporeal blood circulation system or as a temporary respiratory mechanical support known as ECMO that is quickly changed from one into the other, providing the physician with more time to evaluate the real need to install a long term ECMO.

Abstract: The present invention refers to an oximetry and capnography system applied to extracorporeal circulation procedure, more specifically refers to an oximetry and capnography monitoring system associated to gas analyzer applied to ECC, in which a mechanical device (1) based on a tubular circuit (2) is foreseen, and connectors (3) that when duly installed in the equipment operating in ECC have as main purpose to monitor the operation of the gas blender, analyze the oxygenation chamber performance, and check CO2 outflow from the oxygenation chamber in such a way as to prevent collapse within the said oxygenation chamber and therefore, being efficient throughout the ECC procedure.
