What can Smartwatch do in the "Pam-period"?

"Severe symptoms, mild illnesses" seems like most people would face when infecting COVID. And it is best for everyone to do self-testing at home, and to prioritize medical resources on severe and life-threatening patients. Then how do we do a good job of health self-examination? Smart watches. Smart watches have gradually implemented health monitoring functions, which can provide users with health data such as heart rate, blood oxygen, sleep, blood pressure, electrocardiogram, etc. So what can smart watch health monitoring help you in the epidemic?

The meaning of Smartwatch monitoring

First we need to make it clear that the health monitoring function is only an auxiliary reference and cannot be used as a factual basis for medical diagnosis. In terms of accuracy and professionalism, it is still necessary to look for professional diagnosis and treatment.

But does it mean that smart watch health monitoring is useless? no. For example, the heart rate monitoring function, the accuracy of smart watch heart rate monitoring is infinitely close to the data of medical equipment; such as the electrocardiogram test function, many health wear brands have also applied for the second-level medical CFDA and FDA qualifications. Although regular medical institutions can obtain more reliable multi-lead ECG data at a lower cost, even the most powerful consumer-grade smart wearable devices are still impossible to replace in front of professional medical-grade devices. However, under the background of the epidemic and the shortage of public medical resources, self-monitoring and self-protection are the mainstream. Some smart wearable devices can indeed collect basic health data for assessment of physical status.

How Smartwatch work on your well-being?


  • HRV stands for Heart Rate Variability, which is advanced data derived from heart rate collection. Generally speaking, as long as the performance of the PPG unit is sufficient and also supported by algorithm, the HRV data is worth referring to. Generally speaking, a continuous decline in HRV usually indicates that inflammation is developing and the physical state is declining. A steady increase in HRV indicates that the body is strengthening or recovering. During the infection period, all functions of your body will show a downward trend. However, HRV is a trend indicator, and long-term HRV data collection, recording, and analysis are of value. Therefore, smart watch health monitoring is a long-term use and accumulation process. It is not a medical method, but a healthy lifestyle.


  • ECG detection can perform early screening for heart problems, and can visually display the user's maximum and minimum heart rate, QT interval, peak value and HRV in the form of electric waves. The ECG detection of the smart watch is a single-lead electrocardiogram, which is consistent with the heart rate belt in principle. The accuracy may not be as good as the heart rate belt, but it is enough to find problems such as premature beats and missed beats. However, collecting ECG on the wrist requires the cooperation of both hands, so you can only activate it actively, and there is no possibility of automatic monitoring. In the new crown scenario, ECG monitoring has reference value for people with underlying diseases or at risk of cardiovascular diseases. The ECG fluctuations caused by abnormal heart conditions are independent characteristic indicators. Users with medical background can detect these problems at an early stage according to the changes in the ECG. The ECG monitoring algorithms of some wearable devices can also give prompts, such as the Fitaos health monitoring series watches, Veepoo RIG and others can perform ECG monitoring for users and make corresponding assessments at the same time. If there is a problem, they can advise you to seek medical treatment as soon as possible, instead of opening a browser to search for prescriptions. For cardiovascular diseases, please trust professional doctors.

Blood oxygen

  • Blood oxygen monitoring in the COVID-19 scenario is mainly to check blood oxygen indicators, because COVID-19 may cause breathing difficulties, and severe cases may lead to respiratory failure, resulting in a drop in blood oxygen. All sports/smart watches on the market use reflective blood oxygen collection based on PPG units, and the accuracy of each watch varies. Apple, Huawei, etc. are more reliable, but the price is indeed expensive for ordinary people. If you want cost-effective, Fitaos health monitoring series products and Veepoo RIG smart watches are good choices. They are all specially made A brand owner of health monitoring products. Smart watch blood oxygen monitoring can give you feedback on your real-time blood oxygen level to a certain extent, especially at night, if your blood oxygen level is too low, RIG smart watch will turn on the low oxygen wake-up function at night to protect your health.

Body temperature

  • The body temperature monitoring of smart watches is actually based on the combination of optical principles, sensors and algorithms.

  • In fact, many people think that because the temperature on the wrist is inconsistent with the body temperature, and it is easily affected by the environment and the way it is worn, the body temperature detection of smart watches is not very informative. But here, I would like to share my personal experience. The temperature monitoring of smart watches is still useful, especially at night. Because in the sleep state at night, your body temperature is actually roughly constant, and your body movement is at this time, so the body temperature data at this time still have a certain reference. During the period of the new crown infection, patients will have repeated fever, and even have persistent high fever symptoms, but it is impossible to continuously monitor the temperature with a thermometer at night. The temperature detection of the smart watch can help you solve this problem. Take Veepoo RIG as an example. It supports real-time automatic temperature monitoring. Users can see real-time temperature data records and visualized body temperature trend report graphs when they open the proprietary APP, allowing users to more intuitively grasp their own body temperature. Abnormal can seek medical treatment in time. And after the editor's experiment, the difference between the night temperature monitoring of the RIG watch and the thermometer is only about 0.3 degrees, which is of great help to the body's self-examination during infection.

The health monitoring of smart watches can indeed provide a lot of help。 However,there one thing need to reiterate is that the health monitoring of smart watches is not a medical method, and it can cure diseases immediately. On the contrary, health monitoring is a new healthy lifestyle, which requires us to use it for a long time to form a health management habit, which is really beneficial to our health.
