The COVID-19/Omicron epidemic in Hong Kong is severe. In order to protect themselves, citizens are rushing to buy masks, quick test kits, and piridin, and blood oxygen testing equipment has also become one of the targets.

Understand blood oxygen saturation SpO2

Blood oxygen saturation SpO2 (Oxygen saturation) refers to the ratio of oxygenated hemoglobin to total hemoglobin in the blood. The normal blood oxygen concentration ranges from 95-100%, and the gradually hypoxic blood oxygen concentration is between 91-94%. If it is lower than 90%, it is hypoxemia, which may cause symptoms such as shortness of breath, difficulty breathing, rapid heart rate, high blood pressure, dizziness and headache, and even coma in severe cases. Therefore, blood oxygen saturation is a warning signal for detecting health .

Under the detection of the blood oxygen concentration meter, the normal value of blood oxygen saturation is above 95%, and if it is lower than 95%, there will be hypoxia, so pay attention to abnormalities in the body.

The following is the blood oxygen saturation index reference:

Patients with new coronary pneumonia COVID-19/Omicron often have hypoxemia in the body, but the patient does not feel dyspnea, so it is easy to delay medical treatment and delay the condition, and it is more likely to cause sudden sudden death. Therefore, timely grasp of "blood oxygen concentration" is a very important issue in epidemic prevention. At the moment when going out should be reduced and medical resources are relatively precious, in addition to home oximeters, many doctors also share that smart wearables are a good way to easily monitor blood oxygen and other physiological data and do a good job in independent health management.

Diagnosed with a chance to lower blood oxygen

As for blood oxygen equipment, the reason why there has been a rush to buy blood oxygen equipment in the world recently is that the blood oxygen level may drop due to the infection of new coronary pneumonia, but patients are not easy to detect it. Therefore, it is recommended that the confirmed patients check the blood oxygen level once or twice a day while waiting at home and during isolation. If you find that your blood oxygen is lower than 95%, you should seek medical advice as soon as possible. The smart watch can test blood oxygen anytime, anywhere, whether it is during office hours, sports, or at home.

The role of blood oxygen in COVID-19?

Now that pneumonia is mentioned, many people are the first to think: can blood oxygen concentration be used to diagnose new coronary pneumonia COVID-19/Omicron?

Unfortunately, there is currently no scientific literature that clearly supports blood oxygen as a basis for diagnosis. However, since the onset of the disease, more and more voices from the medical community have indicated that knowing the changes in blood oxygen concentration may be used as an early detection of "possibility of diagnosis" omen.

Low blood oxygen saturation can easily lead to shortness of breath, physical fatigue and other symptoms, and too low blood oxygen saturation can damage organ functions. It has been reported that some foreign COVID-19 patients have a state of silent hypoxia (Silent Hypoxia). Although there are no obvious symptoms at the initial stage of diagnosis, the body organs have been damaged to varying degrees, and the condition deteriorates rapidly afterwards. It can be seen that the blood oxygen saturation value is closely related to physical health and can directly reflect health warning signs. For long-term patients and the elderly, using an oximeter to measure blood oxygen saturation can help detect changes in physical conditions and seek medical advice early.
