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 of the result accuracy. The confidence level takes into account 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, and High.
The SDK does not report the confidence level for all indicators. If the confidence level of any indicator is not High, it is recommended to take another measurement and adhere better to the Best Practices.
Indicators Information
The table below indicates the technical information of the supported health indicators. Some indicators are calculated only when the measurement is completed. Their values are reported only when the SDK has gathered enough data to calculate them.
The "Required Measurement Duration" refers to a measurement taken according to the Best Practices" without signal-quality issues. In case of interruptions or mis-detections, the time required for adequate vital signs collection might increase.
