METHOD AND APPARATUS FOR NON-INVASIVE CONTINUOUS MONITORING OF CEREBROVASCULAR AUTOREGULATION STATE

摘要

A non-invasive method for continuous real-time monitoring of cerebrovascularblood flow autoregulation state includes simultaneous non-invasive monitoringof intracranial blood volume respiratory waves and lung volume respiratorywaves, real-time decomposition of intracranial blood volume respiratory wavesand lung volume respiratory waves into narrowband sinewave first harmoniccomponents, determination therefrom of the phase shift between intracranialblood volume respiratory wave and lung volume respiratory wave firstharmonics' and derivation of cerebrovascular autoregulation state from thatphase shift value.
