“…Besides continuous electroencephalogram monitoring, cranial ultrasound, magnetic resonance imaging, and magnetic resonance spectroscopy, near-infrared spectrometry (NIRS)-monitored regional cerebral oxygen saturation (rScO 2 ) is increasingly used (1)(2)(3). NIRS is a noninvasive, bedside technique which can be used to monitor mixed cerebral saturation, which correlates well with venous jugular bulb saturation (4)(5)(6) and estimates oxygen supply to the brain (1,2). Normal values of rScO 2 in the neonatal brain are reported to range from 55 to 85% (2,(4)(5)(6).…”

Background: Near-infrared spectroscopy (NIRS) is an upcoming clinical method for monitoring regional cerebral oxygen saturation (rScO 2 ) in neonates. There is a growing market offering different devices and sensors. Even though this technique is increasingly clinically applied, little is known about the similarities and/or differences in rScO 2 values between the different devices and sensors. The aim of this study was to compare the rScO 2 values obtained in (preterm) neonates with all available sensors of three frequently used NIRS devices. Methods: Fifty-five neonates admitted to our neonatal intensive care unit (NICU) were included in this study. rScO 2 was simultaneously monitored bilaterally with two different NIRS sensors (left and right frontoparietal) for at least 1 h. Then, the sensors were switched, and measurements were collected for at least another hour. results: We detected a rather close correlation between all investigated sensors from the three different NIRS devices, but absolute rScO 2 values showed substantial differences: BlandAltman analysis showed average differences from 10 to 15%. conclusion: Although the rScO 2 values correlated well between different NIRS sensors, sometimes there were substantial differences between the absolute rScO 2 values, which may complicate clinical application.

“…Misra et al (15), using INVOS 3100, recorded a mean CO value of 67.2% ± 8.4%. Yoshitani et al (16), using INVOS 4100 and NIRO 300, found a mean CO value of 66% ± 8% and 66% ± 7%, respectively. In a study of 31 infants, Aldrich et al (17) detected the mean value of CO measured within 30 minutes after delivery as 22-73%.…”

“…The overall bias of )2.1% with wide limits of agreement (1.96 SD limit of agreement of 14.7%) makes interpretation of the absolute values of TOI and rSO 2 difficult and adds to the debate Figure 1 Schematic representation of the study protocol. [15]. The wide limits of agreement suggest that the absolute values for rSO 2 and TOI may be too imprecise for clinical use.…”

SummaryIn this study cerebral oxygenation was measured using the NIRO 300 and the INVOS 5100 spectrophotometers in 10 healthy adult volunteers, exposed to varying degrees of hyperoxia and hypoxia. The results showed similar baseline values for tissue oxygenation index and regional cerebral oxygen saturation with mean (SD) values being 64.9% (5.1) and 62.3% (6.0), respectively. The overall bias was -2.1%, with the INVOS 5100 under-reading cerebral oxygenation compared to the NIRO 300, with limits of agreement of ±14.7%. Both monitors demonstrated similar changes in response to hyperoxia and hypocapnia (coefficient of variance for F I O 2 0.45 ¼ 10.0%, F I O 2 1.0 ¼ 10.1%, hypocapnia ¼ 14.5%). The reasons for the bias and variability may relate to differences in the methodological approaches of the two monitors. The correlation between the monitors in response to changes in cerebral oxygenation implies that they may be useful as trend monitors in clinical practice.
