Increasingly we are monitoring the distribution of oxygen through the microcirculation using optical techniques such as optical reflectance spectroscopy (ORS) and near-infrared spectroscopy. Mean blood oxygen saturation (S(mb)O(2)) and tissue oxygenation index measured by these two techniques, respectively, evoke a concept of the measurement of oxygen delivery to tissue. This study aims to establish whether S(mb)O(2) is an appropriate indicator of tissue oxygenation. Spontaneous fluctuations in… CONTINUE READING
