Aim To compare absolute values of regional cerebral tissue oxygenation (c S t O 2 ) during haemodynamic transition after birth and repeatability during steady state for two commercial near‐infrared spectroscopy ( NIRS ) devices. Methods In a prospective observational study, the INVOS 5100 C and FORE ‐ SIGHT were compared on 12 term newborns delivered by elective caesarean section. During the 10 min following umbilical cord clamping, c S t O 2 was measured simultaneously with the neonatal sensors from each device. Repeated measurements were taken the following day. Results Three and 8 min after clamping, the mean c S t O 2 value increased from 53.4% ( CI 36.8–69.9%) to 86.0% ( CI 80.2–91.7%) for INVOS and from 61.6% ( CI 55.4–67.8%) to 82.2% ( CI 77.7–86.7%) for FORE ‐ SIGHT . The B land– A ltman plot revealed decreasing difference ( INVOS minus FORE ‐ SIGHT ) (D) in absolute values (A) with increasing c S t O 2 ( D = 0.5A – 38.19 p = <0.001). The mean steady‐state value on day two was 78.4% ( CI 74.6–82.2%) and 86.2% ( CI 85.0–87.4%) for INVOS and FORE ‐ SIGHT , respectively. The within‐subject standard deviation during steady‐state repeated measurements was 4.8% ± 0.86 for INVOS and 2.8% ± 0.5 for FORE ‐ SIGHT . Conclusion The INVOS and FORE ‐ SIGHT c S t O 2 estimates showed oxygenation‐level‐dependent difference during birth transition. The better repeatability of FORE ‐ SIGHT could be due to the lower response to change in saturation.
