Abstract
The reliability and accuracy of pulse oximetry as a monitoring device in deep superficial and full-thickness circumferential burns of the upper extremity were evaluated clinically. Pulse oximetry was correlated with the laser Doppler flowmeter experimentally in healthy volunteers. By continuously monitoring oxygen saturation levels, the pulse oximeter detected extremity hypoxia before it resulted in an adverse outcome. Extremities exhibiting oxygen saturation above 95% were treated with early excision and skin grafting without escharotomy. Extremities with O2 saturations of less than 95% underwent immediate escharotomy with return to normal saturation levels. The pulse oximeter is easy to use by nursing personnel; is noninvasive and accurate; and displays the oxygen saturation level within seconds.
