   Pulse oximetry is a tool used for the noninvasive measurement of blood oxygenation (i.e., SpO 2. Pulse oximetry is based on two principles: modulation of transmitted light by absorption of pulsatile arterial blood and different absorption characteristics of HbO 2 and RHb for different wavelengths.

   21 Ιαν 2021 · Most pulse oximeters that are in existence today use a couple of PPGs obtained using red and infrared wavelength light sources and calculate oxygen saturation in arterial blood using the red and IR PPGs and an empirical equation. This chapter details the development of pulse oximetry.
