SD2

The SD2 value is sent as part of the final results.

The application can receive the SD2 result by implementing VitalSignsListener:

SwiftObjective-C

Swift

func onFinalResults(results: VitalSignsResults) {
    DispatchQueue.main.async {
        if let sd2 = results.getResult(of: VitalSignTypes.sd2) as? VitalSignSD2 {
            print("SD2: \(sd2.value)")
        }
    }
}

func onFinalResults(results: VitalSignsResults) {
    DispatchQueue.main.async {
        if let sd2 = results.getResult(of: VitalSignTypes.sd2) as? VitalSignSD2 {
            print("SD2: \(sd2.value)")
        }
    }
}

Objective-C

- (void)onFinalResultsWithResults:(BNHVitalSignsResults *)results {
    dispatch_async(dispatch_get_main_queue(), ^{
        BNHVitalSignSD2 *sd2 = (BNHVitalSignSD2 *)[results getResultOf:BNHVitalSignTypes.sd2];
        if (sd2 != nil) {
            NSLog(@"SD2: %ld", (long)sd2.value);
        }
    });
}

- (void)onFinalResultsWithResults:(BNHVitalSignsResults *)results {
    dispatch_async(dispatch_get_main_queue(), ^{
        BNHVitalSignSD2 *sd2 = (BNHVitalSignSD2 *)[results getResultOf:BNHVitalSignTypes.sd2];
        if (sd2 != nil) {
            NSLog(@"SD2: %ld", (long)sd2.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.
