LF/HF

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

The application can receive the LF/HF result by implementing the OnFinalResults callback interface:

TypeScript

import { 
    VitalSigns,
    VitalSignsResults,
    LfhfSign,
} from '@biosensesignal/web-sdk';

const onFinalResults = useCallback((vitalSignsResults: VitalSignsResults) => {
    const results = vitalSignsResults.results as VitalSigns;
    const lfhf = results.lfhf as LfhfSign;
    if (lfhf?.value != null) {
        console.log(`LFHF: ${lfhf.value}}`);
    }
}, []);

For general information about vital signs see the Vital Signs and Health Indicators Information Document. For additional information regarding the supported indicators see the Indicators Technical Information page.
