Notice: The blood oxygen saturation varies with each person's breathing, and there is a slight difference in the blood oxygen saturation value of different fingers. The oximeter test values are rough estimates only. In order to accurately measure blood oxygen saturation, blood gas analysis is still required, that is, arterial blood needs to be drawn for corresponding detection. In fact, the change of blood oxygen saturation is very large, and it changes almost at any time. For example, if you do a little exercise, your body will consume oxygen, and the data will change. As long as the value remains within the normal range, you need to hold your finger for a longer time during the test. Looking at the average value will be most accurate.
