Wellness Index

The Wellness Index value is sent as part of the final results. It is calculated based on several other indicators and can still be determined even if only a subset of them is available. For optimal results, it is recommended to ensure that the measurement duration is sufficient and that as all relevant indicator values are calculated.

The indicators used in the calculation are:

• Pulse Rate
• Blood Pressure
• Heart Rate Variability (RRi)

The application can receive the Wellness Index result by implementing the OnFinalResults callback interface:

TypeScript

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

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

For general information about vital signs see the Vital Signs and Health Indicators Information Document.

For a list of supported indicators and their required measurement durations, see the Indicators Technical Information page.
