Incorporated to a finger grip device are an oximeter that measures the SpO2of the patient and a fingerprint sensor for sensing the fingerprint of the finger from which the SpO2is measured. The sensed fingerprint is used to identify the patient. By thus establishing the identity of the patient, the measured SpO2could readily be associated with the patient and appropriately displayed and stored, either at the patient site or remotely. The monitored data could also be readily associated with records of the patient and other physiological could data of the patient that may have been prestored in the controller to which the finger grip device is connected, or in a memory at a remote location. Mistakes in patient identification and the correspondence of wrong patient data to patients are thereby substantially reduced if not eliminated.
