What Is Pulse Oximetery?
A Pulse Oximeter is a device that noninvasively measures the oxygen saturation level (SpO2) in the blood, along with pulse rate (PR) and perfusion index (PI), using different wavelengths of light.
PARAMETERS MEASURED WITH THE iSpO2
Oxygen Saturation (SpO2) is a measure of the oxygen saturation level in the blood. Higher oxygen saturation indicates more oxygen in the blood, LOWER OXYGEN SATURATION INDICATES LESS OXYGEN IN THE BLOOD.
Pulse Rate (PR) indicates the number of heart beats per minute.
Perfusion Index (PI) indicates the signal strength from pulsating blood in the artery. A lower PI reading indicates lower blood flow to the finger.
