Recently, many young foreigners have suffered from sequelae. The most important one is cough. Some people even suspect that they have white lungs. Do they want to have a CT examination? When I went to the hospital, I found that the hospital was full of people who wanted to check it, and the queues took a long time. Today I will teach you how to measure blood oxygen using your mobile phone for free. For your reference only. I am using Huawei mobile phone , I don’t know if it can be used on other phones.
1. Open the application market and download Remote Control Wizard
2. After downloading, open the Remote Control Wizard
and click on My in the lower right corner. At this time, anti- new crown will appear. Note that there is no need to register, just click on anti-new crown.
At this time, the mobile phone camera will be displayed to measure blood oxygen and anti-coronavirus. Then click on it, and the blood oxygen measurement interface will appear.
To measure blood oxygen at this time, you only need to put your finger on the camera, cover the camera, keep quiet, breathe smoothly, and it will be measured after a while. I also read other people's articles, and I haven't personally tested their accuracy. According to the person who read the article, there is not much difference with the results of the bracelet test. Although it is not a professional test, it can still be used as a reference.
Note that the measurement should be done in a well-lit place, but not in direct sunlight. You'll understand why when you take the test.
