Masimo - SET Pulse Oximetry
WebThe pulse oximeter works out the oxygen saturation by comparing how much red light and infra red light is absorbed by the blood. Depending on the amounts of oxy Hb and deoxy Hb present, the ratio of the amount of red light absorbed compared to the amount of infrared light absorbed changes.

Oximetry Definition, Test, Types & Readings - MedicineNet
WebConventional pulse oximetry works under the assumption that by looking at only the pulse and normalizing the pulsating signal over the non-pulsating signal, oxygen saturation (SpO 2) can be measured without calibration. WebThe most widely used monitoring tool to keep track of the perfusion index is the pulse oximeter. The perfusion index is calculated by dividing the pulsatile signal (AC) by the non-pulsatile signal (DC), multiplied by 100. This is then expressed as a percentage which ranges from 0.02% to 20%.
