A method and apparatus for performing coronary perfusion and cardiac reoxygenation that enables accurate control of oxygen levels in blood used for the coronary circulation. Deoxygenation blood and oxygenated blood are collected and oxygen levels are measured by sensors, (420, 425). The deoxygenated and oxygenated blood is then mixed and the mixed blood is measured by another sensor (450). The sensors provide data used to provide real-time oxygen level measurement and adjustment for blood supplied for coronary circulation.

La présente invention concerne un procédé et un appareil de perfusion coronaire et réoxygénation cardiaque qui permettent de régler avec précision les niveaux d'oxygène dans le sang utilisé pour la circulation coronaire. Selon l'invention, on recueille le sang désoxygéné et le sang oxygéné et l'on mesure les niveaux d'oxygène à l'aide de capteurs (420, 425). On mélange alors le sang désoxygéné et le sang oxygéné et l'on mesure le sang mélangé à l'aide d'un autre capteur (450). Les capteurs fournissent des données qui sont utilisées pour mesurer en temps réel et ajuster le niveau d'oxygène du sang alimentant la circulation coronaire.
