LF/HF

The LF/HF value is sent as part of the final results.

The application can receive the LF/HF result by using the useFinalResults hook:

TypeScript

import { 
    VitalSignTypes,
    useFinalResults
} from 'biosensesignal-react-native-sdk';

const finalResults = useFinalResults();

React.useEffect(() => {
    if (finalResults) {
        const lfhf = finalResults.getResult(VitalSignTypes.LFHF) as VitalSignLFHF;
        if (lfhf) {
            console.log(`LFHF: ${lfhf.value}`);
        }
    }
}, [finalResults]);

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.
