## Real Time Sample Array; Pleth wave

This example results when the device sends a waveform. The value[x] becomes a valueSampledData data type.

Note there is no logical id in this resource as this resource is being uploaded to the server in a create operation. The server will create the logical id and return it to the sender in the response.
