title: Technical implementation and clinical findings/results of monitoring oxygen saturation in patients referred for long-term EEG monitoring.
abstract: Recent technical developments allow the recording of a patient's oxygen saturation (SpO2) simultaneously with intensive long-term EEG monitoring (LTM). Clinically significant information from this enhanced multi-system physiological monitoring device can contribute to more accurate diagnoses in patients referred for LTM. This report covers the technical usage of combined SpO2/EEG recordings in a small group of patients. Clinically, the findings on the SpO2 monitor helped to define the diagnosis in many of these patients. In a few, the SpO2 changes were diagnostic in their own right and prompted referral to our Sleep Disorders Laboratory. From a research aspect, the details of the morphology and timing of the oxygen desaturations and EEG show several interesting relationships with respect to the dynamics of seizure semiology and respiratory physiology.
