Pulse Rate

The Pulse Rate value is sent both as an instantaneous value during the measurement and as part of the final results.

The application can receive the Pulse Rate result by implementing VitalSignsListener:

Swift

func onVitalSign(vitalSign: VitalSign) {
    DispatchQueue.main.async {
        if (vitalSign.type == VitalSignTypes.pulseRate) {
            if let pulseRate = vitalSign as? VitalSignPulseRate {
                print("Pulse Rate: \(pulseRate.value)")
            }
        }
    }
}

func onFinalResults(results: VitalSignsResults) {
    DispatchQueue.main.async {
        if let pulseRate = results.getResult(of: VitalSignTypes.pulseRate) as? VitalSignPulseRate {
            print("Pulse Rate: \(pulseRate.value)")
            print("Confidence Level: \(pulseRate.confidence?.level ?? ConfidenceLevel.unknown)")
        }
    }
}

Objective-C

- (void)onVitalSignWithVitalSign:(id<BIOVitalSign> _Nullable)vitalSign {
    dispatch_async(dispatch_get_main_queue(), ^{
        if (vitalSign.type == BIOVitalSignTypes.pulseRate) {
            BIOVitalSignPulseRate *pulseRate = (BIOVitalSignPulseRate *)vitalSign;
            if (pulseRate != nil) {
                NSLog(@"Pulse Rate: %ld", (long)pulseRate.value);
            }
        }
    });
}

- (void)onFinalResultsWithResults:(BIOVitalSignsResults *)results {
    dispatch_async(dispatch_get_main_queue(), ^{
        BIOVitalSignPulseRate *pulseRate = (BIOVitalSignPulseRate *)[results getResultOf:BIOVitalSignTypes.pulseRate];
        if (pulseRate != nil) {
            NSLog(@"Pulse Rate: %ld", (long)pulseRate.value);
            
            BIOVitalSignConfidence *confidence = pulseRate.confidence;
            if (confidence != nil) {
                NSLog(@"Confidence Level: %ld", (long)confidence.level);
            }
            else {
                NSLog(@"Confidence Level: %d", 0);
            }
        }
        
    });
}

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.
