PRQ

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

The application can receive the PRQ result by implementing VitalSignsListener:

SwiftObjective-C

Swift

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

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

Objective-C

- (void)onFinalResultsWithResults:(BNHVitalSignsResults *)results {
    dispatch_async(dispatch_get_main_queue(), ^{
        BNHVitalSignPRQ *prq = (BNHVitalSignPRQ *)[results getResultOf:BNHVitalSignTypes.prq];
        if (prq != nil) {
            NSLog(@"PRQ: %f", prq.value);

            BNHVitalSignConfidence *confidence = prq.confidence;
            if (confidence != nil) {
                NSLog(@"Confidence Level: %ld", (long)confidence.level);
            }
            else {
                NSLog(@"Confidence Level: %d", 0);
            }
        }
    });
}

- (void)onFinalResultsWithResults:(BNHVitalSignsResults *)results {
    dispatch_async(dispatch_get_main_queue(), ^{
        BNHVitalSignPRQ *prq = (BNHVitalSignPRQ *)[results getResultOf:BNHVitalSignTypes.prq];
        if (prq != nil) {
            NSLog(@"PRQ: %f", prq.value);

            BNHVitalSignConfidence *confidence = prq.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 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.
