ABSTRACT:
A method of analyzing biological pressure signals in a patient including obtaining arterial blood pressure, cerebral blood flow rate and intracranial pressure signals from the patient, and analyzing frequencies of the signals in relation to a range of target frequencies corresponding to at least one of type-B slow waves, infra-B waves and ultra-B waves; and an apparatus for analyzing biological pressure signals in a patient including an acquisition module, located adjacent to the patient and having input channels that receive signals from an arterial blood pressure (ABP) sensor, a cerebral blood flow rate (CBF) sensor, and an intracranial pressure (ICP) sensor; an analysis module that performs frequency analysis of the signals from a target frequency selected from the group consisting of type B slow waves corresponding to a frequency between 8×10−3hertz and 50×10−3hertz, infra-B waves corresponding to a frequency lower than 8×10−3hertz, and ultra-B waves corresponding to a frequency including between 50×10−3hertz and 200×10−3hertz; and an exploitation and display module optionally located adjacent the patient in the form of an equipment unit or a local work station connected to the analysis module by an internal network or be constituted by a remote working station connected to the analysis module by a communication network.
