Wellness Index

The Wellness Index value is sent as part of the final results. It is calculated based on several other indicators and can still be determined even if only a subset of them is available. For optimal results, it is recommended to ensure that the measurement duration is sufficient and that as all relevant indicator values are calculated.

The indicators used in the calculation are:

Pulse Rate
Oxygen Saturation (SpO₂)
Blood Pressure
Heart Rate Variability (RRi)

The application can receive the Wellness Index result by implementing VitalSignsListener:

SwiftObjective-C

Swift

func onFinalResults(results: VitalSignsResults) {
    DispatchQueue.main.async {
        if let wellnessIndex = results.getResult(of: VitalSignTypes.wellnessIndex) as? VitalSignWellnessIndex {
            print("Wellness Index: \(wellnessIndex.value)")
        }
    }
}

Objective-C

- (void)onFinalResultsWithResults:(BIOVitalSignsResults *)results {
    dispatch_async(dispatch_get_main_queue(), ^{
        BIOVitalSignWellnessIndex *wellnessIndex = (BIOVitalSignWellnessIndex *)[results getResultOf:BIOVitalSignTypes.wellnessIndex];
        if (wellnessIndex != nil) {
            NSLog(@"Wellness Index: %ld", (long)wellnessIndex.value);
        }
    });
}

For general information about vital signs see the Vital Signs and Health Indicators Information Document.

For a list of supported vital signs by platform and measurement mode (face/polar), along with their required measurement durations, refer to the Indicators Technical Information page.

Important

Note that vital signs are sent on a background thread. The application must switch to the UI thread in order to perform UI updates.
