Abstract

The human brain is the organ that consumes the most oxygen in the basal state, when presenting a decrease in oxygen supply, physiological mechanisms are activated to preserve this supply and thus avoid permanent brain injuries. When a brain injury of any cause occurs, it is essential to carry out a correct diagnosis and monitoring, to establish early and effective therapeutic actions to reduce secondary organic damage, seeking to improve the prognosis of patients with severe neurological injuries. Next, a review of the physiology of cerebral metabolism and multimodal perfusion monitoring techniques, measurement of cerebral metabolism and its correct interpretation is carried out.
