BUILDING THE IMPROVE DATA LIBRARY

Well-characterized and comprehensive TV test data sets are essential i n the development and evaluation of biosignal interpretation methods f or intensive-care patient monitoring. The IMPROVE (improving control o f patient status in critical care) Data Library (DL) is an annotated d ata library that contains practically all the monitored and other clin ical data from critically ill patients at high risk of oxygen-transpor t-related problems. The data, collected at the Intensive Care Unit of the Kuopio University Hospital, is supported by continuous patient-sta te assessments carried out by a bedside physician and includes 59 pati ent records, each having a typical duration of 24 hours. In this artic le we describe the technical setup of the system, including what signa ls and parameters were collected and how the annotations were done. We also discuss the lessons learned from data-collection process.
