WebBackground. It is uncertain whether skin pigmentation affects pulse oximeter accuracy at low HbO2 saturation.Methods. The accuracy of finger pulse oximeters during stable, plateau levels of arterial oxygen saturation (Sao2) between 60 and 100% were evaluated in 11 subjects with darkly pigmented skin and in 10 with light skin pigmentation. Oximeters … WebOct 5, 2004 · Due to the shape of the oxyhaemoglobin curve, the saturation starts to fall rapidly at 90%. Limitations. The oximeter averages its readings every 10-20 seconds. Hence, they cannot detect acute desaturation. The finger probe has a response time of approximately 60 seconds, whereas the ear probe has a response time of 10-15 seconds.
