Apparatus for human brain neuroprotection during surgery

A system for human brain neuroprotection of a patient during surgery comprising:

• a heart lung machine that generates a periodic rectangular pulsation of blood flow;
• a non-invasive cerebrovascular autoregulation (CA) monitor configured for recording and monitoring data of the dynamic autoregulation transient functions of the patient CA system;
• a processor configured for processing the recorded data of the patient CA system status monitoring to identify a single CA impairment event;
• and
• wherein the heart-lung machine is configured to be adjusted to regulate the parameters of mean blood flow generated by the heart-lung machine to minimize the duration of the single CA impairment event.
