Figure 5From: Cerebral blood flow during cardiopulmonary bypass in pediatric cardiac surgery: the role of transcranial Doppler – a systematic review of the literatureCerebral blood flow/cerebral metabolic rate of oxygen coupling (CBF/CMRO2) during cardiac surgery. Group A-moderate hypothermia-, Group B-deep hypothermic cardiopulmonary bypass (CPB) with maintenance of continuous flow, Group C-deep hypothermic circulatory arrest. Stage I = pre CPB; II and III = CPB cold; IV = rewarm; V = post CPB (From 15).Back to article page
