摘要

the present invention relates to a system (1) for estimating blood volume in the brain and / or blood flow in the brain and / or the depth of a patient's anesthesia, comprising at least one excitation electrode (110e) to be arranged on a patient's head (20) to apply an excitation signal, at least one reading electrode (110s) to be arranged on the patient's head (20) to read a signal measurement caused by the excitation signal, and a processor device (12) to process said measurement signal (vc) read by at least one reading electrode (110s) to determine an indicative output of blood volume in the brain and / or of blood flow in the brain. here, the processor device (12) is constituted to reduce noise in the measurement signal (vc) by applying a non-linear noise reduction algorithm. thus a system for estimating blood volume in the brain and / or blood flow in a patient's brain is provided which can lead to greater precision and thereby more accurate estimates.
