Abstract

Effect of carboxyhemoglobin (HbCO) on the readings of pulse oximeters were studied by computer simulations, in vitro experiments and human subject experiments. Results show that the error of pulse oximeter readings is about 1% of functional arterial oxygen saturation when percent carboxyhemoglobin is around 15%. On the other hand, the difference between the reading of a pulse oximeter and percent oxyhemoglobin exceeds 10% under the same conditions. This result shows that the readings of pulse oximeters can be very misleading and should be carefully interpreted when a significant amount of HbCO exists in blood.
