title: Pulse oximetry.
abstract: Pulse oximetry is one of the most commonly applied technologies in acute and critical care. It has the potential to continuously monitor pulmonary function, avoid unnecessary blood gases, and alert clinicians to hypoxemic events that are not readily apparent by physical assessment. Due to these advantages, pulse oximetry has a firm place in health care. Unfortunately, pulse oximetry will not usually have a major impact on reducing hospital resources. In addition, oximetry has the potential to be misused owing to its widespread application. In order to obtain the maximum benefits from this technology, clinicians must be educated about the strengths and limitations of oximetry. If this education effectively changes clinicians' behavior, pulse oximetry will provide an excellent clinical advantage in patient assessment as well as moderate cost benefits.
