简要总结

The aim of this study is to characterize the noise in the SpO2 signal depending on different pulse oximeter averaging time settings.

详细描述

Noise in the SpO2 signal is most often caused by artifacts, such as movement artifacts, reduced perfusion, additional light and others. These artifacts can be partially removed from the SpO2 signal by different pulse oximeter settings, specifically the sensitivity mode and averaging time. It is known that when a longer averaging time is set, the measured signal contains fewer artifacts, on the other hand there is an increased risk of missing short desaturation. The aim of this work is to characterize the noise in the SpO2 signal depending on the set averaging time of the pulse oximeter based on experimental data from healthy volunteers.
