Non-invasive Cerebral Autoregulation monitoring during Cardiac Surgery

Abstract

The results of the ongoing preliminary study of non-invasive cerebral autoregulation (CA) monitoring during the cardiac surgery with the cardiopulmonary bypass (CPB) are presented. It is shown that the CA impairment events during CPB may be consequence of the temporarily dropped mean arterial blood pressure (MAP) below the lowest individual MAP threshold; and the duration of CA impairment events is associated with the deteriorated mental abilities. The „Vittamed” non-invasive CA monitor can be used for individual patient-specific MAP management during the CPB in order to prevent brain injuries and cognitive dysfunctions.
