Evaluation of a new pulse oximeter sensor.
BACKGROUND A new forehead noninvasive oxygen saturation sensor may improve signal quality in patients with low cardiac index. OBJECTIVES To examine agreement between oxygen saturation values obtained by using digit-based and forehead pulse oximeters with arterial oxygen saturation in patients with low cardiac index. METHODS A method-comparison study was used to examine the agreement between...

Pulse oximeters have become standard equipment in both biomedical education and clinical settings. Since the operational principles of a pulse oximeter are straightforward, and since the analysis of these sensor data require basic computational and mathematical toolsets, this type of device is well suited to hands-on experiences geared toward both undergraduate and graduate students. However, t...
متن کاملEvaluation of the Ohmeda 3700 pulse oximeter.
Arterial oxygen saturation values (Sao2) from 60% to 98% were measured by the Ohmeda 3700 pulse oximeter with the three types of probe available and compared with values of oxygen saturation estimated from direct arterial sampling (arterial oxygen and carbon dioxide tensions and pH) on 65 occasions. The response time of the oximeter was measured after a sudden rise in inspired oxygen concentrat...
متن کاملComparison of a new forehead reflectance pulse oximeter sensor with a conventional digit sensor in pediatric patients.
BACKGROUND During conditions of poor perfusion, the accuracy of conventional extremity-based pulse oximeters may be limited. Limited evidence suggests that forehead perfusion may be better preserved during such periods, but pediatric experience with newer forehead reflectance sensors is limited. We prospectively compared the accuracy of a forehead reflectance sensor, the Max-Fast, with a new-ge...
