The biomedical value of nearinfrared spectroscopy (NIRS) is its ability to record oxygen levels, especially StO 2 , in a noninvasive manner. In clinical cases, peripheral StO 2 values recorded from the forearm and thenar regions are frequently used as surrogates for central oxygen levels. Thus,...
Near infrared spectroscopy (NIRS), the technique on which Artinis devices e.g.The OxyMon,Brite family, andPortaMonare based, relies mainly on two characteristics of human tissue. First, the relative transparency of tissue to light in the NIR range, and second, the oxygenation-dependent light abs...
Near-infrared spectroscopy (NIRS)has been widely utilized in food and feed, polymers and textiles since the 1980s, with other industries such as pharmaceuticals, personal care and petroleum products adopting this technique later on. NIRS can be used to detect overtones and combination bands of mole...

Near infrared spectroscopy has also been used to evaluate systemic perfusion in patients undergoing first-stage palliation for hypoplastic left heart syndrome. Despite shortcomings in the ability of NIRS technology to accurately reflect validated and directly measured parameters of systemic oxygen delivery ...
The near-infrared spectroscopy (NIRS) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from 780 to 2500nm) to detect and measure chromophores that are related to the color of molecules such as myoglobin, oxyhemoglobin, and deoxyhemoglobin. ...
