AbstractThree cases representing the emergency department use of pulse oximetry are described. A brief review of the principles of operation of pulse oximetry, as well as a discussion of recent literature and clinical uses of the technology, is presented. While not replacing arterial blood gases in the assessment of critically ill patients, a more widespread use of pulse oximetry in evaluating emergency department patients might provide significant information in the management of patients with respiratory complaints. Pulse oximetry may also play an important role in monitoring those patients requiring airway interventions such as assisted ventilation or endotracheal intubation.
