SD2

The SD2 value is sent as part of the final results.

The application can receive the SD2 result by using the useFinalResults hook:

TypeScript

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

const finalResults = useFinalResults();

React.useEffect(() => {
    if (finalResults) {
        const sd2 = finalResults.getResult(VitalSignTypes.SD2) as VitalSignSD2;
        if (sd2) {
            console.log(`SD2: ${sd2.value}`);
        }
    }
}, [finalResults]);

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.
