PNS Index

The PNS Index value is sent as part of the final results.

The application can receive the PNS Index result by implementing VitalSignsListener:

Swift

func onFinalResults(results: VitalSignsResults) {
    DispatchQueue.main.async {
        if let pnsIndex = results.getResult(of: VitalSignTypes.pnsIndex) as? VitalSignPNSIndex {
            print("PNS Index: \(pnsIndex.value)")
        }
    }
}

Objective-C

- (void)onFinalResultsWithResults:(BIOVitalSignsResults *)results {
    dispatch_async(dispatch_get_main_queue(), ^{
        BIOVitalSignPNSIndex *pnsIndex = (BIOVitalSignPNSIndex *)[results getResultOf:BIOVitalSignTypes.pnsIndex];
        if (pnsIndex != nil) {
            NSLog(@"PNS Index: %f", pnsIndex.value);
        }
    });
}

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.

Important

Note that vital signs are sent on a background thread. The application must switch to the UI thread in order to perform UI updates.
