Improved method and apparatus for detecting optical pulses. |
摘要 |
<p>A method and apparatus for improving the calculation of oxygen saturation and other blood constituents by non-invasive pulse oximeters. The method and apparatus permit more accurate determination of blood flow by collecting time-measures of the absorption signal at two or more wavelengths and processing the collected time-measure to obtain composite pulsatile flow data from which artifacts have been filtered. The processing occurs in the frequency domain. The time-measure is Fourier transformed into its spectral components to form the composite information.</p> |
