About pulse blood oxygen meter.
In addition to heart rate, blood pressure, respiratory frequency and temperature, pulse blood oxygen (PO) is considered to be ranked 5th in the most critical health status indicators. Hemoglobin (HB) is an important part of blood cells that transport oxygen from the lungs to other tissues of the body. The amount of oxygen that hemoglobin contains at any given moment is called oxygen saturation. Oxygen saturation is expressed as a percentage, which is the ratio of oxygen content of hemoglobin to the oxygen carrying capacity of hemoglobin. Blood oxygen saturation is an important physiological parameter to reflect the normal respiration function and oxygen content of human body, and it is an important physiological parameter to show the health of our bodies. Severe hypoxia can directly lead to asphyxia, shock, death and other tragedies. In Europe and the United States and other developed countries, the monitoring of blood oxygen is very important, blood oxygen instrument has a high penetration rate.
