AbstractPulse oximetry is a noninvasive method of measuring arterial oxygen saturation. The value of oximetry in patients with burn injuries has been questioned because of a theoretic inaccuracy in the presence of carboxyhemoglobin. We studied pulse oximetry in 27 intubated patients with burn injuries to determine the accuracy of the method and then to determine whether oximetry could replace indwelling catheters presently used for arterial blood gas analysis. Oximeter and arterial blood gas saturation data correlated closely, with a coefficient of 0.820. The pulse oximeter predicted "adequate" ventilation in 78% of patients with a readout of 99% or above. The arterial PO2 was greater than or equal to 90 torr in 90% of patients with oximetric readouts greater than or equal to 98% and in 10% of patients with readouts less than 95%. Pulse oximetry is an accurate adjunct in the management of patients with burn injuries and in addition provides continuous real-time data not available with arterial blood gas sampling.
