Blood oxygen measurement is beginning to be mainstream. Manufacturers are adding this function through updates with a clear example in Huawei, which recently updated its Huawei Watch GT 2 with this function, present natively in the Huawei Watch GT 2e.
Similarly, we have news that the Huawei Band 4 has been the next to update to receive this news. Through a update software, this sports bracelet is already capable of measuring oxygen saturation in the blood.
The economic Huawei Band 4 already measures blood oxygen saturation
Thanks to the measurement of oxygen saturation in the blood we can estimate the levels of it running through our bloodstream. Thanks to this measurement, we can prevent problems such as hypoxemia, produced when there is a decrease in arterial oxygen pressure.
Despite the low weight of the update, it is a good leap at the software level, improvements in the experience of use with the bracelet are promised, in addition to enabling the SpO2 sensor for the measurement of oxygen in blood
Specifically, the Huawei Band 4 is receiving this functionality through firmware update 22.214.171.124., with a weight of only 5.46 megabytes and that includes other improvements for the device, as indicated in the list of changes (not very specific).
- Enable the SpO2 sensor
- Optimize the user experience
- Optimize the training experience
- Optimize the Alarm function
- Fix some display issues
As is customary in Huawei, the update it will arrive in batches, so you may not have it immediately. If so, you just have to wait a few days for it to arrive. Remember also that for security reasons the bracelet must have at least 20% battery before updating. Finally, indicate that Huawei indicates an installation time for this update close to 20 minutes.
