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.
