Evaluation of analytic and motion-resistant performance of the Mindray 9006 pulse oximeter.
BACKGROUND
The Mindray 9006 is a newly developed pulse oximeter. The performance of noninvasive monitoring of arterial oxygen saturation by pulse oximetry (SpO(2)) and pulse rate (PR) with the Mindray 9006 was evaluated.


METHODS
Twenty healthy volunteers participated in this study. The Mindray 9006 was evaluated according to guidelines including HS3-A, EP5-A, and EP9-A2 published by the CLSI, and ISO 9919. A blinded side-by-side comparison of the Mindray 9006 and the Masimo MS-3 oximeter was also performed.


RESULTS
The results demonstrated that the coefficients of variation (CV) of imprecision were less than 1% for SpO(2) and less than 5% for PR analyzed by the Mindray 9006. Comparisons of methods showed there was no significant difference in SpO(2)/PR analysis between the Mindray 9006 with Rapidlab 855 CO-oxymeter or 812 Electrocardiogram (ECG) monitor (p>0.05) and between the Mindray 9006 and Masimo MS-3 (p>0.05). There was good correlation for SpO(2) between the Mindray 9006 and CO-oxymetry or the Masimo MS-3 (r>0.96) and for PR between the Mindray 9006 and ECG or the Masimo MS-3 (r>0.98). The accuracy as the root-mean-square (A(rms)) was less than 3% for both SpO(2) and PR between the Mindray 9006 and CO-oxymetry or between the Mindray 9006 and ECG. Also, there was no significant difference for SpO(2)/PR between the motion and rest conditions (p>0.05).


CONCLUSIONS
The overall performance of the Mindray 9006 for SpO(2) and PR analysis is excellent and compares favorably with the Masimo MS-3.
