Hemoglobin

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

This indicator is supported for face measurements on iPhones.

The application can receive the Hemoglobin result by implementing VitalSignsListener:

SwiftObjective-C

Swift

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

Objective-C

- (void)onFinalResultsWithResults:(BIOVitalSignsResults *)results {
    dispatch_async(dispatch_get_main_queue(), ^{
        BIOVitalSignHemoglobin *hemoglobin = (BIOVitalSignHemoglobin *)[results getResultOf:BIOVitalSignTypes.hemoglobin];
        if (hemoglobin != nil) {
            NSLog(@"Hemoglobin: %f", hemoglobin.value);
        }
    });
}

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

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

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.
