What is Blood Oxygen Saturation?
Blood oxygen saturation level refers to the percentage of a person’s red blood cells that are loaded or filled with oxygen.The blood oxygen saturation of normal human arterial blood is 98%, and the blood oxygen saturation of venous blood is 75%. It is generally believed that the normal value of blood oxygen saturation should not be lower than 94%, and below 94% is considered insufficient oxygen supply. If your blood oxygen saturation is persistently below 95%, it is likely that you have inflammation in your lungs.
As we all know, the COVID-19 has spread across the world in recent years. Not only that, but the virus can easily cause infections in people's lungs, which can lower blood oxygen levels. The continuous decline in blood oxygen saturation is one of the main symptoms of COVID-19 infection.
According to the 2021 British Medical Journal (BMJ) clinical event guidance for home management of COVID-19, it is pointed out that the normal blood oxygen concentration of ordinary healthy people is between 94% and 98%. If it is lower than 92% after infection with COVID-19, the patient is considered to be seriously ill and should seek urgent medical attention.
If it is between 93% and 94%, further observation is required, and according to the situation, go to a community clinic for medical treatment.
How to measure blood oxygen saturation?
In daily life, we can test ourselves through the oximeter. The oximeter is one of the clinical diagnostic tools for COVID-19. The pulse oximeter launched by BIOBASE is small in size, light in weight and easy to carry. And its high measurement accuracy is loved by the majority of users.
At present, pulse oximeters are widely used in homes, clinics, oxygen bars, sports health care, community medical care and other places.
Not only that, the display interface of the BIOBASE pulse oximeter is simple and easy to observe. At the same time, the operation of this product is also very simple. We only need to clamp it on our fingers to measure when we are in a calm state.
Who needs an oximeter?
1. People with cardiovascular and cerebrovascular diseases (such as coronary heart disease, high blood pressure, etc.)
2. People with respiratory diseases (such as asthma, bronchitis, cor pulmonale, etc.)
3. Seniors over 60 years old
4. Chronic alcoholics and heavy smokers
5. People who work more than 12 hours a day
6. Blood oxygen monitoring in extreme sports and alpine hypoxic environment
7. Patients infected with COVID-19
8. Immunodeficiency (such as AIDS patients, etc.)
Kind tips
If you feel dyspnea, you need to go to the hospital in time even if your blood oxygen saturation is normal. In addition, if the blood oxygen saturation fluctuates greatly in a short period of time, it is also recommended to seek medical treatment in time.
