Method for continuous cerebral autoregulation monitoring and diagnostic device

摘要

A method for continuous cerebral autoregulation monitoring comprising: measuring the blood pressure (21) of a patient (1); Measuring the cerebral blood flow velocity (22) of the patient (1); Repeating the two measurements; and estimating the transinformation based on measurements of blood pressure (21) and cerebral blood flow velocity (22); characterized in that the transinformation is calculated based on the formula T = -∫∫ρ · ln (ρ) · dv, where T is the transinformation, ρ is a phase space density (23), v is the blood flow velocity (22), p is the blood pressure (21 ) and in the natural logarithm, where the phase space density (23) is estimated from measurements of blood pressure (21) and cerebral blood flow velocity (22).
