Paper Abstract

It has been shown that near-infrared spectroscopy is a feasible technique to non-invasively measure tissue pH in vivo. Since this technique relies on pH-induced changes in heme protein spectra, other factors that affect those spectra were investigated. In this study, the correlation between spectra collected from the bowel (575 - 1100 nm) with local tissue temperature and blood flow were investigated simultaneously with pH changes during eight independent swine hemorrhagic shock experiments.
