Description:
The Qiyi Smartwatch KC08 is a multi-functional wrist-monitor. Medaval has not found evidence proving the accuracy of its blood pressure measurement technology and information regarding the accuracy of its oxygen saturation measurement technology does not appear to be available. Blood pressure measurements and oxygen saturation measurements are taken from the wrist. It is intended for self-measurement and home use.
Assessment:
There appears to be no peer-reviewed clinical validation information available on the technology used in the Qiyi Smartwatch KC08 either to measure blood pressure or to measure peripheral oxygen saturation.
Recommendations:
| Accuracy Assessment | Recommendation | Basis | |
| BP | Medaval | Not recommended | This device has not been clinically validated. |
