Mean RRi 
The Mean RRi value is sent as part of the final results.
The application can receive the Mean RRi result by using the useFinalResults hook:
TypeScript
import { 
    VitalSignTypes,
    useFinalResults
} from 'binah-react-native-sdk';
const finalResults = useFinalResults();
React.useEffect(() => {
    if (finalResults) {
        const meanRRi = finalResults.getResult(VitalSignTypes.MEAN_RRI);
        if (meanRRi) {
            console.log(`Mean RRI: ${meanRRi.value}`);
            console.log(`Confidence Level: ${meanRRi.confidence?.level.toString() ?? "N/A"}`);
        }
    }
}, [finalResults]);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.
