With the gradual opening of the epidemic, the prevention and control of the epidemic depends more on self-protection, monitoring and isolation. Self-health monitoring and management is becoming more and more important. Therefore, we need to have a clear understanding of COVID-19 's infectious ways and symptoms, so that we can make a early identification. And as we all know, body temperature is an important index for screening COVID-19 patients, but there is another extremely important index for diagnosis and treatment, which is easy to be ignored or even not well known by the public, that is, blood oxygen saturation (SpO2).
In the clinical symptoms of the COVID-19, most people have dyspnea and hypoxia. The relevant clinical conclusions prove that patients with new coronary pneumonia can be diagnosed as clinically severe when the blood oxygen saturation is less than or equal to 93% in a resting state. At this time, the patient will have severe dyspnea or hypoxemia, and frequent hypoxia will cause chronic damage to various organs. Prolonged hypoxia may also cause serious diseases such as myocardial infarction, cerebral infarction, and pulmonary infarction. , or even life-threatening, emergency treatment measures such as respiratory support must be taken in time. In the new situation of the epidemic, blood oxygen monitoring at home and knowing the blood oxygen value at any time can help us better protect ourselves and protect our own health.
What are the symptoms of hypoxia（low of SPO2）?
The face, lips or nails are in an ischemic state
Shortness of breath, difficulty breathing or worsening cough
Increased heart rate
When is self blood oxygen monitoring necessary?
During the epidemic, self-test blood oxygen saturation in isolation at home.
During the recovery period of patients with new coronary pneumonia, evaluate the recovery of lung function.
People infected with COVID-19 (including asymptomatic ones) need to self-test their oxygen saturation. 4. Patients with high blood pressure, cardiovascular and cerebrovascular diseases, normal vascular function and blood circulation are affected, and hypoxia is prone to occur.
Middle-aged and elderly people over 60 years old, with age, the function of heart and lungs and other organs declines, metabolism slows down, and their sensitivity to hypoxia is poor.
People who snore at night, especially those who are prone to OSH, such as obesity, smoking and drinking, and middle-aged and elderly people, will experience hypoxia due to repeated apnea at night.
Pregnant mothers, especially in the middle and late stages of pregnancy, are prone to umbilical cord around the neck and other symptoms of hypoxia, which have a greater impact on the fetus.
For those who exercise regularly, high-intensity physical exercise will increase the body's oxygen consumption in a short period of time, and short-term hypoxia will occur. If combined with chronic diseases or sub-health status, the hypoxic state will be aggravated.
People who work hard for more than 10 hours a day, especially high-intensity mental activities, will increase the oxygen consumption of the brain, resulting in insufficient oxygen supply.
Smartwatches help self-monitor blood oxygen
There are also special blood oxygen detection instruments on the market, but they need to be carried for a single operation, which is very inconvenient for real-time blood oxygen monitoring. Wearing a smart watch on your hand can help you easily achieve self-blood oxygen monitoring. During the three years of the epidemic, health monitoring technology has developed rapidly. The blood oxygen monitoring technology of smart watches has been widely used, such as Apple's S8, Huawei's health monitoring series, Veepoo RIG, Garmin and other products are deserve to try.
Taking Veepoo RIG as an example, the RIG smart watch supports the blood oxygen monitoring function, uses optical principles, is equipped with advanced sensors, and relies on its own patented algorithm technology to provide blood oxygen data with higher precision. The specific working principle is: use photoplethysmography to absorb the irradiation of LED light from the watch through the skin, detect the blood concentration change caused by heart pressure, and calculate the blood oxygen saturation of the artery by using the change of arterial blood flow. Most importantly, Veepoo RIG is more cost-effective than the brands recommended above.
