Stress Index ​

The Stress Index value is sent as part of the final results.

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

Swift
func onFinalResults(results: VitalSignsResults) {
    DispatchQueue.main.async {
        if let stressIndex = results.getResult(of: VitalSignTypes.stressIndex) as? VitalSignStressIndex {
            print("Stress Index: \(stressIndex.value)")
        }
    }
}
Objective-C
- (void)onFinalResultsWithResults:(BNHVitalSignsResults *)results {
    dispatch_async(dispatch_get_main_queue(), ^{
        BNHVitalSignStressIndex *stressIndex = (BNHVitalSignStressIndex *)[results getResultOf:BNHVitalSignTypes.stressIndex];
        if (stressIndex != nil) {
            NSLog(@"Stress Index: %ld", (long)stressIndex.value);
        }
    });
}

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

For a list of supported vital signs per platform and measurement mode (face/finger) see the Supported Vital Signs 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.
