  1. Vent nomenclature – semantic architecture - “Finite State Model (FSM)” perspective- Architecture J. Wittenber, N. Jones d9w08Mar10 ISO/IEEE11073/IHE/IEC JWG on Vent Nomenclature

  2. Intro • This paper updates the “Finite State Model (FSM)” perspective • General: Descriptive language • Architectural • Graphical • Relational*, Tabular • Ontological • And includes several annotated wave examples from literature for discussion and validation purposes *Initial harmonization with emerging related standards • Risk Management for MedDevs in HC IT Networks (ISO/IEC 80001-1) • Particular requirements for basic safety and essential performance of critical care ventilators (ISO/IEC 80601-2-12) ISO/IEEE11073/IHE/IEC JWG on Vent Nomenclature

  3. Vent Nomenclature – Mode - Descriptive language - General Notes: 1 From “Classes Properties & Attributes of the Elements of Ventilation.xlsx”[Jones/Dain] and related ontology (see slide). ISO/IEEE11073/IHE/IEC JWG on Vent Nomenclature

  4. Vent Nomenclature –FSM - Architecture – Graphical view ISO/IEEE11073/IHE/IEC JWG on Vent Nomenclature

  5. Vent Nomenclature –FSM - Architecture – Relational, Tabular view • Attribute value sets are taken combinationally to derive an FSM path • “f(χ)”  analogical transfer function, typ. a [low-order ] polynomial, esp. constant or slope @ P, Q, V. • See slide “Notes” for more definition on Attributes See Examples (2) (1) ISO/IEEE11073/IHE/IEC JWG on Vent Nomenclature
