ICM+ Features

  • Encapsulates almost 20 years of experience of brain monitoring gained using ICM (Intensive Care Monitor-DOS version 3), Computerized Infusion Test [1,2], Biological Signal Recorder (MREC and WREC [28]) and Cerebrovascular Laboratory Signal Analyser [21] in different centres (Cambridge, Warsaw, Copenhagen, Geteborg, Detroit, Toulouse, and many others).
  • Monitors multiple variables through analogue and digital inputs.
  • Covers variety of aspects of multimodal bedside brain monitoring: ICP, arterial pressure, brain oxygenation, blood flow, neurotrending, brain temperature and many others.
  • Calculates on-line indices describing autoregulation of cerebral blood flow [4,6], cerebrospinal compensation [15], vascular reactivity [25].
  • Incorporates various methods and tests used in diagnosis of hydrocephalus: overnight ICP monitoring [5], infusion study [2], testing of performance of implanted shunts in-vivo [7,8].
  • Supports testing of transient hyperaemic response [19,22], leg-cuff autoregulation [22] and CO2 reactivity [10,23]; calculates non-invasive CPP [18].
  • Enables modification of existing methods of brain monitoring and development of new algorithms through extensive programming of signal analysis.
  • Aids the integration of physiological monitoring with clinical observations using an extensive mechanisms of user definable events. All the clinical notes and events are treated as paper based doctor notes i.e. each entry is flagged with time stamp, user name and is not editable once inserted.
  • In addition to time trends of various indices and summary measures of monitored signals, also saves raw data [21,28], which enables building up a library of signals for post-processing.
  • Provides various time period based chart tools for investigation of time trends properties and correlations between them both in time and frequency domain.
  • Provides tools for off-line data browsing/analysis including: magnifying glass, selection tool, summary statistics calculator, cursor that can be synchronised amongs panels, panels time synchronisation tool, data filtering options (including median filter for spurious artefact elimination), annotations mechanism for marking up the analysed data, intelligent file search tool and more.
  • Incorporates extensive user security mechanism with easily definable user groups and privilages system.
  • Complies with the Data Protection Act by providing strong encryption of all the clinical data - it also facilitates data exchange between centres by providing additional selective encryption of patient identifying details using user defined passphrase.
  • Stores the results in easily viewed files; exports data in text format; imports data from previous applications.
