More Information
Summary:Embodiments of the present invention relate to a pulse oximeter sensor comprising a light source configured to emit light, a detector configured to detect light after the light has been scattered by tissue, and a limiting component configured to limit light signals received at the detector from the light source to three or less spectra, wherein the three or less spectra include a first spectrum having a mean wavelength in an infrared range of 805 nanometers to 940 nanometers, and a second spectrum having a mean wavelength of 700 nanometers to 790 nanometers used in conjunction with the first spectrum for measuring oxygen saturation in a patient.
