Abstract

Noninvasive determination of oxygen delivery to the brain was obtained by using a newly designed three wavelength optical system, which consists of low power laser diodes and photo detectors. Using this near-infrared spectroscopy (NIRS) system, the authors investigated the relationship between directly measured jugular venous O₂ saturation (S_jO₂) and regional cerebral O₂ saturation (rSHbO₂) as determined by NIRS. Results from ten cardiac surgical patients show good quantitative correlations
