ICEPAC Project Prospectus - Draft 2a Jan Wittenber ISO/IEEE Upper Layers Subcmte Chair November 13, 2008

2 Developed for IHE PCD DPI ICEPAC working group Scope and purpose: To provide initial set of materials for discussion concerning technical content and project planning

3 Topics Technical content Overview Detail Topology (Care areas, Modalities, Info) Data flow Risk-managed Supy Ctl & Data Acqn (SCADA) ICE perspective Risk Mgmt perspective Standards considerations Architectural Roadmap See Appendix A for Abbreviations

4 Technical content – Modeling overview Supervisory Control and Data Acquisition (SCADA) perspective Topological perspective Risk Analysis cases ICE Use cases Devices (Medical, Network Infrastructure, User I/F) Care areas (Use contexts), e.g. ICU, PACU, OR Data Types Data Flows Control characterizn Risk/Safety considerations

5 Detail – Topological perspective

6 Detail – Info Vectors A B A) B)

7 Detail – Data Flow (Left side, e.g. ICU)

8 Detail – Data Flow (Right side, e.g. OR)

9 Detail – ICE Use Cases Examples

10 Detail – Risk Management (RM) perspective Example

11 Topological perspective Topological perspective Detail – Risk managed Supervisory Control and Data Acquisition (SCADA) perspective Risk Managed SCADA

12 Detail – Risk managed Supervisory Control and Data Acquisition (SCADA) perspective SCADA Risk Managed

13 Detail – Risk managed SCADA – Xray-Resp Sync - Schema WHILE EXC_DATA_LOSS = TRUE {ALERT, INHIBIT ACTUATION} ACTUATE XRAY EXPOSURE WHEN END_INSPIRATION = TRUE

14 Standards considerations - x73 data language – Service and Control subject Activate Operation ActuateXRayExposure; StartApneaCtlMode; etc. e.g. Limit Alert Operation Hi/Lo HR, RR, SpO2, etc. Set Value Operation InfRate, RespRate, Gain, etc. Select Item Operation Choice of SampleRate or Period, Gain, etc. Toggle Flag Operation ToggleAlarmsOnOff; TogglePauseResume; etc. e.g.:

15 Standards considerations – x73 data language (MDDL) – overview See detail NomenclatureDIMMDIB in operating context

16 Standards considerations – x73 data language impacts l Nomenclature adaptations needed l Virtual Attributes partition finalized, incl. l X Remote Control Package (RCoP) l IHE PCD Rosetta, esp. Ventilator extensions l ICEPAC extensions l Control sequences imply need for rigorous control language to express safety criteria and [effective] performance l Is C[++] acceptable? l Some specialized control language? l FSM-oriented? l OO abstractions (e.g. Interlock) may be needed

17 Standards considerations – x73 architecture ICE Svc Elem Specializations Generalizations For standards modeling purposes, assume that there is an ICE SE. Combination of components: - Information objects (OO abstractions) - Nomenclature - Services - Protocols - Management (e.g. system health test; conformance)
