Popis: We performed laboratory evaluation of six pulse oximeters from different manufacturers using the Fluke 2XL SpO2 simulator. The pulse oximeter probes were labeled 1 through 6 and tested using the two pre-programed preset functions of the Fluke 2XL SpO2 simulator, level 01 and level 02, for their performance in the presence of motion artifacts. The pulse oximeters were also tested at low perfusion index (PI) settings. The accuracy of the individual probes was ranked as good, mediocre, or poor based on the degree of deviation of the measured SpO2 and pulse rate (PR) by the probes from that generated by the simulator in both the presence and absence of motion artifacts and at lower PI. In preset level 01, probes numbered 1, 2, and 6 performed flawlessly, probes numbered 3, 4, and 5 performed poorly. In preset level 02, all probes performed well in the absence of motion artifacts. When probes were attached in the absence of motion, but readings were recorded after the emergence of motion artifacts, probes 1, 2, and 6 continued to perform well. However, the performance of probes 3, 4, and 5 deteriorated. When probes were attached directly in the presence of motion artifacts, probes 2 and 6 performed well, whereas all other probes performed poorly. Successively lowering the PI degraded performance of probes 3, 4, and 5 at extremely low PI. It is observed that during motion and/or low PI conditions, multiple probes see deterioration in performance.
