Abstract
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. Deoxygenated blood and oxygenated blood are collected and oxygen levels are measured by sensors. The deoxygenated and oxygenated blood is then mixed and the mixed blood is measured by another sensor. The sensors provide data used to provide real-time oxygen level measurement and adjustment for blood supplied for coronary circulation.
Claims10
A method of mitigating additive injury during percutaneous coronary intervention comprising controlling perfusion and reoxygenation of a tissue in a patient during the intervention, wherein the perfusion is controlled by a coronary perfusion device wherein the coronary perfusion device comprises:
- (a) a first blood supply configured to hold deoxygenated blood;
- (b) a second blood supply configured to hold oxygenated blood;
- (c) an oxygenation controller configured to mix amounts of blood from the first and second blood supplies, thereby creating a third blood supply;
- and (d) at least one sensor configured to measure oxygen levels of blood in the third blood supply and provide the measured oxygen levels to the oxygenation controller;
- wherein the third blood supply provides a perfusate for coronary circulation.
