Cardiothoracic & vascular anesthesia
A comparison of the NeurOs® and the INVOS 5100C® cerebral oximeter during variations of the partial pressure of carbon dioxide and fractional inspiratory concentration of oxygen
Authors' conclusion
The ScO2 measurement performance of the NeurOs® cerebral oximeter is not interchangeable with the INVOS® cerebral oximeter during variations of ventilation and oxygenation in elective cardiac or vascular surgical patients.
Study context
- Population
- Anesthetized cardiac and vascular surgical patients during hemodynamically stable conditionspooled data
- Participants
- 59 participants
- Exposure
- NeurOs® vs INVOS 5100C® cerebral oximeter
- Outcome
- Agreement of ScO2 measurement (Bland-Altman bias and limits of agreement) during variations of PaCO2 and of SaO2 by FiO2
Methodological detailsprospective
- Prospective
Main finding
As reported in the abstract
- Bias, PaCO2 variation
- - 0.5%
- Lower limit of agreement, PaCO2 variation (95% CI - 19.6 to - 13.7%)
- - 16.3%
- Upper limit of agreement, PaCO2 variation
- 15.4% (95% CI 12.8 to 18.8%)
- Bias, saturation (SaO2) variation by fraction of oxygen (FiO2)
- - 0.8%
- Lower limit of agreement, SaO2 variation (95% CI - 19.7 to - 13.6%)
- - 16.3%
- Upper limit of agreement, SaO2 variation
- 14.7% (95% CI 12.1 to 18.2%)
Observational data: associations, not effects.
Further findings
Baseline agreement by NeurOs® sensor version
- Comparable bias and limits of agreement with bi-hemispherical sensor and two-sensor version
ScO2 in default vs high penetration mode (newer NeurOs® version)
- No significant differences in ScO2
