OXYGEN SATURATION WITH SIMULATED BREATHING

摘要

We describe a systematic procedure to arrive at the optimal wavelengths for monitoring oxygen delivery to and its consumption in an organ. On the basis of the signal-to-noise optimization study, we propose several high performance 2-D wavelength intervals within the therapeutic window. Furthermore, we find that at least one of the traditional wavelength choices falls near the interval of decreased performance, providing a possible explanation for the occasional failure of currently used devices.
