CarbiScan is a medical grade gas containing carbon dioxide balanced with oxygen and nitrogen added to inhaled gases to increase arterial partial pressure of carbon dioxide, which stimulates increases in cerebral blood flow

The Brain Stress Test gauges the adequacy and pattern of brain blood flow reserve by administering a standardized cerebral vasoactive stimulus and measuring indicators of the flow response throughout the brain. It is scored in comparison to the normal range as determined from an age and sex matched healthy cohort
