What is blood oxygen saturation?

Human blood carries oxygen through the combination of red blood cells and oxygen.
The oxygen needed in our metabolism process enters through the respiratory system, combines with the hemoglobin in the red blood cells to form oxygenated hemoglobin, and then transports it to the tissues and cells of the human body.
The saturation of blood oxygen is an important physiological parameter that reflects the function of breathing and circulation, and it is an index to measure the ability of human blood to carry oxygen. In addition to heart rate, blood pressure, respiratory rate and body temperature, pulse oximetry is also considered to be the fifth key health indicator.

The practical application of blood oxygen saturation in daily life

  • People with heart disease, high blood pressure, diabetes, people with respiratory diseases

Monitoring blood oxygen indicators can provide a good understanding of whether one’s respiratory system and immune system are normal; follow up the effect of treatment by testing blood oxygen. Patients must monitor blood oxygen during first aid and transport, fire fighting, and high-altitude flights; medical staff also use blood oxygen as a mandatory monitoring item during ward rounds and outpatient visits;

  • Seniors over 60

The heart and lung organs are physiologically aging, with insufficient oxygen uptake and insufficient oxygen supply.
The human body relies on blood to transmit oxygen. If there is less blood, there will be less oxygen. If there is less oxygen, the physical condition will naturally decline. The elderly regularly check the blood oxygen level. Once the blood oxygen is below the warning level, oxygen can be supplemented as soon as possible.

  • Snorer

There are many people around us who snore when sleeping. If you look closely, you will find that people who snore can not breathe and stop breathing for a long time. But because we fall asleep, we actually I don’t know what the current situation is. If you review the data during sleep, you can see the changes in blood oxygen saturation during this period and the duration of the hypoxemia state, which can also help us discover the severity of the problem in time. Degree and take precautions before they happen.

  • Outdoor athletes, mountaineering enthusiasts, sports people

Monitor blood oxygen during exercise, know your physical condition in time, and take necessary protective measures. When you are engaged in outdoor activities at a rapidly changing altitude, monitoring blood oxygen saturation (SpO2) can assess your physical condition in real time and adjust the current appropriate intensity. These data can allow you to understand how your body responds to the changing environment.
At high altitudes, people are prone to symptoms of hypoxia. The lack of endogenous oxygen generally manifests as: dizziness, headache, tinnitus, vertigo, weak limbs; or nausea, vomiting, palpitation, shortness of breath, shortness of breath, shortness of breath, fast and weak heartbeat. Generally, low blood oxygen saturation is increased by inhaling oxygen, which is why we have altitude sickness when we go to the plateau and we need to bring a portable oxygen cylinder.

  • People who work more than 12 hours a day

The brain’s oxygen consumption increases, and the oxygen supply cannot meet the consumption
The oxygen consumption of the brain accounts for 20% of the whole body oxygen uptake. The brain’s oxygen consumption will inevitably increase with the transition of mental work. The human body can take in limited oxygen, consumes more, and consumes less. In addition to causing dizziness, fatigue, poor memory, slow response and other problems, it can also cause serious damage to the brain and myocardium. Even death from overwork. People who study or work for more than 12 hours a day need to strengthen their blood oxygen and sleep conditions. Monitoring

  • Long-term alcoholics

The human body needs three units of oxygen for every unit of alcohol that is completely decomposed into water and carbon dioxide. Therefore, hypoxia is one of the important manifestations of drunkenness. However, long-term alcoholics have developed a certain tolerance to alcohol and hypoxia, and they are basically unable to detect them when they are slightly drunk. Such people need to pay more attention to observe their blood oxygen changes.
