A second version of Kelvin is under development to allow for the following: - confirmation, or marking as erroneous, measurements held within the archive, the PC application to automate the setting up of measurement type codes, the retrieval of a subset of measurements for a particular measurement type by specifying a range of reference values e.g. just the last hour.  Kelvin is being considered for archiving long term monitoring as in ITU, electrophysiological studies as in EEG, laboratory results and even ward-based observations where the medical device may simply be replaced by a form on a web page.
