PNS Index ​

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

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

Swift
func onFinalResults(results: VitalSignsResults) {
    DispatchQueue.main.async {
        if let pnsIndex = results.getResult(of: VitalSignTypes.pnsIndex) as? VitalSignPNSIndex {
            print("PNS Index: \(pnsIndex.value)")
        }
    }
}
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:(BNHVitalSignsResults *)results {
    dispatch_async(dispatch_get_main_queue(), ^{
        BNHVitalSignPNSIndex *pnsIndex = (BNHVitalSignPNSIndex *)[results getResultOf:BNHVitalSignTypes.pnsIndex];
        if (pnsIndex != nil) {
            NSLog(@"PNS Index: %f", pnsIndex.value);
        }
    });
}
- (void)onFinalResultsWithResults:(BNHVitalSignsResults *)results {
    dispatch_async(dispatch_get_main_queue(), ^{
        BNHVitalSignPNSIndex *pnsIndex = (BNHVitalSignPNSIndex *)[results getResultOf:BNHVitalSignTypes.pnsIndex];
        if (pnsIndex != nil) {
            NSLog(@"PNS Index: %f", pnsIndex.value);
        }
    });
}

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

For a list of supported vital signs per platform and measurement mode (face/finger) see the Supported Vital Signs Page.

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.
