Abstract

Previously the NIRS oximeter OxyPrem was calibrated by comparison to the INVOS in a blood-lipid phantom. The aim of the present study was to test this calibration clinically. During vasculur occlusions in 10 adults and after birth in 25 term infants the relationship was OxyPrem = 1.24 x INVOS - 23.6% and OxyPrem = 1.15 x INVOS - 16.2% on the adult arm and infant head, respectively. The precsion during steady state was 4.0% (CI 3.4% to 4.6%) and 3.4% (CI 2.9% to 3.9%) on the arm, and 6.7% (CI 5.9% to 7.6%) and 4.7% (CI 3.5% to 5.9%) on the infant head for OxyPrem and INVOS, respectively. We conclude that the calibration on the blood-lipid phantom was unsuccessful in achieving agreement in clinical measurements.

Figures (6)

Fig. 1
Fig. 1 The OxyPrem sensor (left handside) and INVOS adult SomaSensor. The position of light detectors (D) and light sources (S) are indicated.
Fig. 2
Fig. 2 The approximate sensor positions on the lower arm.
Fig. 3
Fig. 3 An example of the rStO2 time series during six vascular occlusions. The solid line is INVOS and the dashed line is OxyPrem. The arrows pointing downwards indicate beginning of cuff inflation and the upwards pointing indicate the beginning of cuff deflation. The horizontal double-headed arrow denotes the time of sensors shifting placement. The segments with thicker lines represent the data used for fitting the mixed effects model.

Fig. 4 Scatter plot and linear fit of INVOS rStO2 vs. OxyPrem rStO2 values from one minute segments after vascular occlusion. The points from each occlusion are joined.
Fig. 5
Fig. 5 An example of the rStO2 time series during the 10 minutes following umbilical cord clamping in a single subject. The solid line is INVOS and the dashed line is OxyPrem.
Fig. 6
Fig. 6 Scatter plot and linear fit of INVOS rStO2 vs. OxyPrem rStO2 values from 2.5 to 4.5 minutes after cord clamping. The points from each infant are joined.
