Oxygen saturation (the concentration of oxygen in the blood) is usually the amount of oxygen in the blood.
Oxygen saturation in humans is generally the percentage value of the degree of saturation achieved by hemoglobin in the body as it combines with oxygen.
Most of the blood oxygen saturation can be judged with the help of blood gas analysis, usually can be divided into arterial oxygen saturation and venous oxygen saturation, the normal human arterial oxygen saturation range of most of the 95% to 100%, most of the venous oxygen saturation is more than 75%, the oxygen saturation test is conducive to clarifying whether the blood oxygen is in the normal range, the occurrence of the value of the low value suggests that the body has a lack of oxygen and blood circulation disorders, may be the occurrence of the blood oxygen content. Low blood oxygen saturation value indicates the presence of insufficient blood oxygen and blood circulation disorder, which may be caused by lung disease or cardiovascular disease.
Abnormal blood oxygen saturation needs to go to the hospital to improve the relevant examination and treatment.
