A pulse oximetry device and method of operating a pulse oximetry device

摘要

A pulse oximetry apparatus includes a light emitting device configured to emit light having a wavelength of a first wavelength interval and light having a wavelength of a second wavelength interval, a first light detector configured to detect light having a wavelength of the first wavelength interval however, not to respond to light having a wavelength from the second wavelength interval, and a second light detector configured to detect light having a wavelength from the first wavelength interval and light having a wavelength from the second wavelength interval.
