The invention discloses a non-invasive monitoring method and a monitoring device for cerebral blood
oxygen, and develops a non-invasive monitoring method for blood
oxygen saturation of local tissues of a
human brain by utilizing different absorbances of oxyhemoglobin and deoxidized
hemoglobin to near-
infrared light, so that the method does not cause harm to a
human body; continuous real-time monitoring of the cerebral blood
oxygen value can be achieved through a continuous cerebral blood oxygen value prediction model, the influence of
melanin is considered, correction factors are added, surface interference signals and deep useful signals are detected respectively, the content of the collected signals is richer, and the cerebral blood oxygen signals with the high
signal-to-
noise ratio canbe obtained through
processing conveniently; further, the cerebral
forehead lobe area local
oxyhemoglobin saturation monitoring value without the
human head tissue interference
signal is solved, so that the cerebral oxyhemoglobin
continuous monitoring stability is better, and the monitoring precision is higher. A new solution is provided for non-invasive monitoring of cerebral blood oxygen, and clinical application of non-invasive monitoring of cerebral blood oxygen can be better promoted.
