Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
It is a "proof of concept" study, aimed to evaluate whether the "optimal CPP", defined by the best PRx, corresponds to the acceptable CBF values.
Patients admitted with the diagnosis of TBI and SAH in for whom ICP and CPP needs to be monitored on clinical ground will be also monitored with a TD probe and routinely tested for cerebral autoregulation, thus obtaining the CBF corresponding at a given the "best CPP" and autoregulation status.
Continuous CBF measures and PRx monitoring may allow more accurate identification and early detection of adverse cerebral conditions. This approach may bring us a step closer to the goal of outcome improvements in patients suffering from intracranial insult.
