These transactions contain the discrete data from the remote Personal Health Device, such as device identification data, data related to the settings and calibration of the device, and the sensor data itself over at least one of several transport options. The transaction supports five transport options. To qualify as PCHA data certain time stamping requirements must be met; e.g., all stored data must be time stamped and any device containing timestamps in the measurements must expose its sense of current time and its time synchronization (if any).
