Necessity of continuous blood oxygen monitoring: protecting health in real time. It is recommended not to close it.
Blood oxygen saturation refers to the percentage of oxygenated hemoglobin bound by oxygen in blood to all hemoglobin, that is, blood oxygen concentration. According to this physiological parameter, we can judge the progress of human respiratory and circulatory system and affect human metabolism. If the blood oxygen is low (normal value ≥92%), there will be insufficient oxygen supply or severe hypoxia, which will easily lead to ventricular fibrillation, cardiac arrest, and even heart and lung diseases such as coronary heart disease and myocardial infarction. At present, there are three groups of people who need to pay special attention to oxygen saturation: the elderly/people with respiratory diseases, people with excessive mental work, and people with exercise/altitude hypoxia environment.
