What is the accuracy of oxygen sensor?

The SpO2 reading should always be considered an estimate of oxygen saturation. For example, if an FDA-cleared pulse oximeter reads 90%, then the true oxygen saturation in the blood is generally between 86-94%. Pulse oximeter accuracy is highest at saturations of 90-100%, intermediate at 80-90%, and lowest below 80%.

The normal amount of SpO2 in healthy individuals is 97% to 99% [8]. If the SaO2 is 70% to 100%, the amount of SpO2 has high accuracy and is 2% different from the SaO2 amount obtained from ABG analysis [5]. Yet, in more critically ill patients, the amount of pulse oximetry error is reported as 7.2% [9].
