Abstract
A method and apparatus for simultaneously determining a patient's identification and blood oxygen saturation are provided. An pulse oximeter probe carries a light source such as LEDs or lasers which is used to read patient identification information carried on the patient's wristband by a bar code. Alternately, the patient's wristband incorporates a radio frequency reader chip which contains the patient's identification information and the pulse oximeter probe carries an antenna adjacent its cable so that, when the pulse oximeter is turned on, it reads the chip in the wristband during the same motion with which the patient's oxygen blood saturation is measured with the pulse oximeter.
