Comparison of cerebral oxygen saturation values measured by different brands of near-infrared spectrometers under hypoxic conditions: a randomized controlled trial in healthy volunteers

Objective By comparing the differences in cerebral oxygen parameters with 3 brands of near-infrared spectrometers, INVOS 5100C (Medtronic), EGOS-600 (Aegean) and BRS-1 (Casibrain Technology), to investigate their consistency, correlation and ability to detect key desaturation events in healthy volun...

Summary:Objective By comparing the differences in cerebral oxygen parameters with 3 brands of near-infrared spectrometers, INVOS 5100C (Medtronic), EGOS-600 (Aegean) and BRS-1 (Casibrain Technology), to investigate their consistency, correlation and ability to detect key desaturation events in healthy volunteers in a hypoxic condition. Methods From December 6, 2021 to January 18, 2022, 20 healthy volunteers were recruited from our hospital. They were randomly divided into group E (a single sensor of INVOS 5100C at the left forehead and that of EGOS-600 at the right) and group B (INVOS 5100C and BRS-1, as the other group), with 10 subjects in each group. After the sensors were applied to the forehead of the subject, hypoxia was induced and reversed by adjusting the ratio of inhaled nitrogen to oxygen. Regional cerebral oxygen saturation (rSO2), heart rate and pulse oxygen saturation (SPO2) were continuously monitored and recorded in the whole process. Wilcoxon test was used to assess the baseline value and changes in
