Abstract

Although different monitoring technologies have been used during cardiopulmonary bypass (CPB), neurological sequelae are frequently found in cardiac surgery patients (Shaw, 1987). Many factors have been considered responsible such as perfusion flow rate (Kolkka, 1980), arterial carbon dioxide tension (Bashein, 1990), microembolism (Gallagher, 1973), and release of biocompatible materials. These factors can affect the intraoperative oxygen supply to the brain modifying the arterial oxygen saturation, the total and regional cerebral blood flow, and the hemoglobin (Hb) content.
