The significance of measuring blood oxygen is mainly to understand the ability of human blood to carry oxygen, i.e. the concentration of oxygen in the blood. Oxygen saturation is a measure of the ability of human blood to carry oxygen and is one of the important parameters for health monitoring.
The normal range of blood oxygen saturation is usually between 95% and 99%. If the blood oxygen saturation is below the normal range, it may imply the presence of hypoxia or insufficient oxygen supply. Many clinical diseases, such as chronic obstructive pulmonary disease, heart failure, anemia, etc., may lead to a decrease in blood oxygen saturation, affecting normal cellular metabolism, and may even be life-threatening in severe cases.
Therefore, measuring blood oxygen can help us understand the body's ability to absorb oxygen as well as the amount of oxygen delivered to the body, which is important for assessing a person's overall health. Especially during the New Crown Epidemic, blood oxygen saturation testing was widely used to identify and treat people with mild to moderate infections, as well as to monitor recovery during the rehabilitation process.
