Transfer function assessment of dynamic cerebral autoregulation
This review contains up-to-date data about the essence of the transfer function method, its place among other methods of investigation of cerebral autoregulation, as well as its advantages and disadvantages. Cererbral autoregulation determines the relationship between cerebral blood flow and cerebral perfusion pressure, thus information about it is important for diagnostics and prognosis of cerebral blood flow dysfunctions. Dynamic cerebral autoregulation is a frequency-dependent phenomenon functioning as a high-pass filter. Transfer function analysis is one of three methods most often used to investigate dynamic cerebral autoregulation, which has significantly developed within two last decades.
