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:

Kotlin
override fun onVitalSign(vitalSign: VitalSign) {
    runOnUiThread {
        if (vitalSign.type == VitalSignTypes.PULSE_RATE) {
            (vitalSign as? VitalSignPulseRate)?.let { pulseRate ->
                Log.i("VITAL SIGN", "Pulse Rate: ${pulseRate.value}")
            }        
        }
    }
}

override fun onFinalResults(results: VitalSignsResults) {
    runOnUiThread {
        (results.getResult(VitalSignTypes.PULSE_RATE) as? VitalSignPulseRate)?.let { pulseRate ->
            Log.i("VITAL SIGN", "Pulse Rate: ${pulseRate.value}")
            Log.i("VITAL SIGN", "Confidence Level: ${pulseRate.confidence?.level?.name ?: "N/A"}")
        }
    }
}
Java
@Override
public void onVitalSign(final VitalSign vitalSign) {
    runOnUiThread(() -> {
        if (vitalSign.getType() == VitalSignTypes.PULSE_RATE) {
            VitalSignPulseRate pulseRate = (VitalSignPulseRate) vitalSign;
            Log.i("VITAL SIGN", "Pulse Rate: " + pulseRate.getValue());
        }
    });
}

public void onFinalResults(final VitalSignsResults results) {
    runOnUiThread(() -> {
        VitalSignPulseRate pulseRate = (VitalSignPulseRate) results.getResult(VitalSignTypes.PULSE_RATE);
        if (pulseRate != null) {
            Log.i("VITAL SIGN", "Pulse Rate: " + pulseRate.getValue());
            VitalSignConfidence confidence = pulseRate.getConfidence();
            Log.i("VITAL SIGN", "Confidence Level: "+ confidence != null ? confidence.getLevel().name() : "N/A");
            
        }
    });
}

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.
