Three devices used to measure hemoglobin oxygen saturation in the extracorporeal circuit were studied and compared to a control. The Baxter Bentley OxySat, Oximetrix Accusat, and the Radiometer ABL4 blood gas monitor were compared to a control, the IL 282 CoOximeter. Fifty one sample points were obtained during all phases of cardiopulmonary bypass with results as follows:
Comparison of Oxygen Saturation Devices
r | DIFF | SD | P | |
---|---|---|---|---|
ACCUSAT | 0.94 p<.0001 | -0.6 | 3.2 | 0.1834 NS |
ABL4 | 0.93 p<.0001 | -1.7 | 3.3 | 0.0008 S |
OXYSAT | 0.87 p<.0001 | -6.8 | 4.4 | 0.0001 S |
r = correlation coefficient with corresponding p value, DIFF = difference from control, SD=Standard deviation of difference, P = p value for testing the hypothesis of no difference between test device and control, NS = No significant difference, S = Significant difference
The Accusat was found to be a statistically more accurate means of monitoring hemoglobin oxygen saturations during cardiopulmonary bypass than the ABL4 and the OxySat. All devices had significant correlation with the control and with each other.
Key words: Cardiopulmonary bypass / venous oxygen saturation / oxygen consumption / fiber optics / wavelengths
