First Claim
1. A method for supporting variability analyses conducted over time at a plurality of sites, each variability analysis comprising computing a measure of variability for a plurality of time intervals for one or more parameters, each measure of variability indicative of a degree and character to which a respective parameter changes over an interval of time, said method comprising:
- providing a connection between a central service and said plurality of sites;
said central service obtaining from each of said plurality of sites, a data package comprising one or more data files representing results of one or more variability analyses conducted at a respective one of said plurality of sites;
said central service storing said data packages in a central database and making said database available for further processing;
said central service providing threshold data to at least one of said plurality of sites, said threshold data comprising information pertaining to parameters of said variability analyses and being derived from the contents of said central database; and
said central service providing update data to at least one of said plurality of sites, said update data comprising information for maintaining consistency among the operation of said plurality of sites.

Abstract
A system is provided for leveraging the power of the analysis of variability over time, and which uses an underlying framework that can handle variability analyses across a distributed system in a consistent manner, in part by constructing a standard variability data file that includes several manifestations of the underlying data acquired using variability monitoring. The consistent and standard data files, along with the underlying framework enables a user to make use of a set of convenient display tools, while a central entity can provide connectivity to the distributed environment and provide a way to update the equipment and software to ensure consistent and relevant analyses. The system can be extended into many environments, including in-patient, out-patient and completely mobile/stand-alone users.
