Blood oxygen refers to the oxygen in the blood. Humans rely on oxygen to survive, and after it is inhaled into the lungs, the oxygen enters the blood through capillaries. The blood then delivers the oxygen to various organs and cells in the body for use. The higher the amount of oxygen in the blood, the better the human metabolism.
 
Finger pulse oximetry refers to the arterial blood oxygen saturation, and the normal value of arterial blood oxygen saturation should be above 95%. If oxygen is inhaled, it is basically 100%. If the arterial blood oxygen saturation is less than 95%, it is necessary to find the cause of the decrease in blood oxygen saturation.
Low blood oxygen saturation can be caused by a variety of factors, mainly including the following aspects: 1. Diseases of the respiratory system, such as the lungs, bronchi, bronchiectasis, and emphysema. 2. Diseases of the cardiovascular system, such as coronary heart disease, unstable angina, myocardial infarction, heart failure, and dilated cardiomyopathy. 3. Drug poisoning, ketoacidosis, etc.
