Abstract: An oximetry and capnography monitoring system associated to a gas analyzer applied to an ECC procedure, in which a mechanical device based on a tubular circuit is contemplated, such that when the device is connected to the ECC equipment with the main purposes of monitoring the operation of the gas blender, analyzing the oxygenation chamber performance, and checking carbon dioxide outflow from the oxygenation chamber in such a way to prevent collapse within the oxygenation chamber and therefore increasing efficiency throughout the ECC procedure.
