Pulse oximetry device and method of operating pulse oximetry device

摘要

The present invention detects a light emitting device designed to emit light having a wavelength from the first wavelength section and light having a wavelength from the second wavelength section, and light having the wavelength from the first wavelength section. However, the first photodetector designed so as not to react to the light of the wavelength from the second wavelength section, the light of the wavelength from the first wavelength section and the light of the wavelength from the second wavelength section And a second photodetector designed to detect.
