Determination of Cerebral Venous Hemoglobin Saturation by Derivative Near Infrared Spectrosocpy delivery and O. consumption and is organ specific. Near infrared spectroscopy (NIRS) was developed to monitor changes in brain hemodynamics and O. utilization (Jobsis, 1977; Wyatt et al., 1986; Ferrari et al., 1987). Quantification of the NIRS data has been difficult, therefore a new method was dev屈尊 发表于 2025-3-25 12:59:49
Near Infrared Determined Cerebral Transit Time and Oxy- and Deoxyhemoglobin Relationships During Hemmic reserve (Gibbs et al., 1984). A usual finding of positron emission tomography studies is a fall of the CBF/cerebral blood volume (CBV) ratio, mathematically equivalent to an increase of the mean transit time (MTT) (Zierler, 1965).发芽 发表于 2025-3-25 16:35:16
Near Infrared Quadruple Wavelength Spectrophotometry of the Rat Headsed as a direct indicator of the sufficiency of oxygen supply to the site of cellular energy production, the mitochondria. The enzyme when oxidized has a broad absorption band in near infrared region and this absorption disappears when its copper component is reduced. Because the extinction coefficiMyofibrils 发表于 2025-3-25 21:54:54
The Oxygen Dependency of the Redox State of Heme and Copper in Cytochrome Oxidase ,e, it is possible to monitor the tissue blood content, hemoglobin saturation level, and the redox state of copper in cytochrome oxidase. The redox behaviour of heme a+a. in cytochrome oxidase and its use as an indicator of tissue oxygenation under low oxygen concentrations has already been studied bcliche 发表于 2025-3-26 02:38:17
Exponential Attenuation of Light Along Nonlinear Path Through the Biological Modelare intensely light scattering within this range. As a result, the optical pathlength through the tissue is significantly different from the spacing between the points incidented and transmitted. Beer-Lambert law that stands for clear solution can’t be simply applied to the tissue and various deviceEtymology 发表于 2025-3-26 07:51:40
Behavior of the Copper Band of Cytochrome , Oxidase in Rat Brain During FC-43-for-Blood Substitutiond (NIR) light by tissue chromophores. Soft tissues and bone are relatively translucent to near infrared light. Hemoglobin (Hb), oxyhemoglobin (HbO.) and the oxidized copper band of cytochrome c oxidase (cytochrome a,a.) have oxygen-dependent absorption spectra in the 700-900 nm wavelength region.

Toward Absolute Reflectance Oximetry: I. Theoretical Consideration for Noninvasive Tissue Reflectancromes which participate in oxygen transport to tissues. Since the influence of light on these pigments can be made really small, transmission and reflection photometry can be useful tools to noninvasively evaluate the oxygenation process that takes place in various tissues. Historically, the applicaComplement 发表于 2025-3-26 16:07:51
New Instrument for Monitoring Hemoglobin Oxygenation case of human newborn, it is important for us to monitor the oxygenation state of hemoglobin in cerebrum. But we have no instrument to monitor it non-invasively, directly and simply. In this case we usually use the percutaneous oxygen electrode monitor or the pulseoximeter.
