Normal blood oxygen saturation in a healthy person is approximately 95-100%. If oxygen levels fall below this level, lung disease may be present. A level below 92% (in the case of chronic obstructive pulmonary disease — COPD, 88%) indicates a serious condition that may require supplemental oxygen or hospital monitoring.
The higher the oxygen saturation in the blood, the better the metabolism of the body. However, it does not mean that the higher is better. Too high will cause cell aging; too low will cause insufficient oxygen supply to the body, accompanied by dizziness, sleepiness, irritability, and other symptoms.
So who will need to monitor this indicator in daily life? Should you really monitor your blood oxygen levels at home? Wellue teams have made the following summary.
1. Patients with COVID-19 including those who have confirmed or suspected COVID-19
A drop in blood oxygen saturation is one of several typical symptoms of coronavirus and a valid indication to distinguish coronavirus from the common cold. Patients with lung infections tend to have decreased blood oxygen saturation, and this also applies to COVID-19. The epidemic is still spreading but the medical system’s support has collapsed, leaving many patients in home isolation. Controlling the infection is a key to prevention and control this epidemic. The epidemic should continue to exist this year, while local outbreaks are likely to occur. Then once you find your blood oxygen saturation suddenly low in daily life, you need to pay enough attention and seek timely medical attention.
Wellue hands over its remote solution. Its Oxylink Remote Oxygen Monitor proves its value in telemedicine.

2. Patients with chronic diseases such as diabetes, heart disease, respiratory disease, sleep apnea etc.
Patients with chronic diseases such as diabetes, heart disease and respiratory diseases, especially the elderly, are characterized by low cure rates, high incidence of complications, and high death rates. They may require long-term care and need to keep good habits to slow down the development and deterioration of the disease. Thus daily monitoring of physical signs and symptoms is particularly important.
In addition to some common self-monitoring indicators such as heart rate, blood pressure and body temperature, with more and more smart wearable devices adding the function of blood oxygen monitoring, blood oxygen monitoring has also become popular. And for patients with chronic diseases, the continuous monitoring of this indicator has become easier. Just using a pulse oximeter to take an instant check is not so helpful. Wellue creates its oxygen monitors for long-term tracking of your SpO2 and pulse rate, such as O2Ring continuous oxygen monitor, Checkme O2 Max Wrist oxygen monitor. By recording these indicators continuously, not only can you better manage your health data outside of the hospital, but you can also go to the hospital for timely follow-up examinations based on the deterioration of the indicators. At the same time, the trend changes of these data are also very important for doctors to diagnose and adjust the treatment plan.
3. Exercise enthusiasts
Like chronic disease patients, it is also very necessary to monitor exercisers’ vital signs to adjust the intensity and frequency of exercise. Especially when doing high-intensity exercise, they are easy to have an insufficient oxygen supply. In serious cases, acute ischemia, cardiac arrest, and interruption of cerebral blood flow may be led, which can cause sudden cardiac death and sudden death, as evidenced by the fact that there have been a number of reports of sudden death in sports this year. So it is very important to reasonably grasp the intensity of exercise.
