Confidence Level
The confidence level of a vital sign indicates the probability of accuracy of the measurement result for that vital sign. The higher the level, the greater the probability and accuracy of the result. The confidence level takes into consideration all the inputs required to calculate a result, including signal quality, any warnings during the measurement duration, and the specific data required for the vital sign, such as the amount of information needed to measure a result. The confidence level values are low, medium, high, and unknown. The accuracy report refers to results in which the confidence level is high.
The SDK Accuracy Targets are available in this document.
It is recommended that the application advises the user to follow the guidelines described in best practices on how to take a measurement and repeat the measurement as needed.
The confidence values will be reported to the application as part of the final report for each of the following vital signs:
Note
If there is insufficient data to calculate the vital sign result at the end of the measurement, neither the vital sign result nor its confidence level will be included in the final report.
