Brief Summary
In cardiac operations under cardiopulmonary bypass(CPB), monitoring of brain tissue oxygen saturation with infrared spectrophotoscopy leads to a reduction of the number of packed red cell(PRC) transfusions during the period of extracorporeal circulation.

Eligibility Criteria
You may qualify if:
- Cardiac operations under cardiopulmonary bypass, consequently (including coronary-aortic bypass graft), valve replacement, surgery of the ascending aorta, combined procedures, redo-operations)
You may not qualify if:
- Cardiac operations without the aid of extracorporeal circulation (ex. "off-pump" techniques)
- Emergency operations
