Overview of artifacts and deviating values. This overview shows that the percentages of artifacts and deviating values for heart rate and oxygen saturation measured by pulse oximetry (Spo2) were relatively low. End-tidal carbon dioxide (ETco2) values most often deviated outside the predefined reference range, and these values also contained relatively many artifacts. Mean noninvasive blood pressure (NIBP) and invasive blood pressure (IBP) demonstrated the most nondeviating values being artifacts.
