Where remote clinical support is required Tempus has a fully integrated ReachBak set of features. These allow a user to connect over an available wide area network such as WiFi, Ethernet, or using the built in cell-phone technology. Tempus incorporates a voice headset to allow the operator to connect to a response centre where clinicians can view the data in real time. The response centre user has access to the complete set of data including real-time medical readings and waveforms; vital signs trends, ECGs, images and summary record of care information. The integrated ReachBak communications are designed to operate reliably over highly challenging network conditions that are often experienced in remote locations; these challenges include handling high latency, network losses and unusual jitter.
