PRQ

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

The application can receive the PRQ result by implementing VitalSignsListener:

Dart

@override
void onFinalResults(VitalSignsResults results) {
    VitalSign? vitalSign = results.getResult(VitalSignTypes.prq);
    if (vitalSign is VitalSignPrq) {
        print("PRQ: ${vitalSign.value}");
        print("Confidence Level: ${vitalSign.confidence?.level.toString() ?? "N/A"}");
    }
}

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.
