Paper Abstract

We present preliminary results of non-invasive, near-infrared measurements of venous saturation (SvO2) on the leg muscle of three anesthetized piglets. We have quantified the local SvO2 by analyzing the optical spectrum of the amplitude of the absorption oscillations synchronous with breathing. To induce a variation in the muscle SvO2, we performed measurements during a protocol involving a cyclic change in the fraction of oxygen inspired by the piglet over the range 10-100% (by volume). In all three piglets, we have found a good agreement between the SvO2 values measured non-invasively with near-infrared spectroscopy (NIRS) and those measured invasively by the analysis of venous blood samples.
