  1. ISO/IEEE 11073-10101Vital Signs Nomenclature June 25, 2007 Contributions: Paul Schluter (GE Healthcare) … and the IEEE 11073 General Committee

  2. ISO/IEEE 11073-10101 Nomenclature What is it? • A structured and comprehensive nomenclaturefor vital signs devices and physiologic data • Numeric parameters, waveforms, body sites … • Alerts and Alarms • Device status and control • Units-of-measure Adoption • ISO/IEEE International Standard (2004) • ISO/IEEE 11073 family of standards • X73_PH Personal Health Working Group (Continua focus) • IHE PCD-01 Profile, using HL7 V2.X messaging

  3. ISO/IEEE 11073-10101 Term Definitions Each nomenclature term definition includes … Reference ID MDC_ECG_HEART_RATE Serves as programmatic handle Used as identifier in HL7 V3 and V2 messages Numeric code 16770 16-bit, context-sensitive (binary messaging) Systematic Name Rate | Beats | Heart | CVS Differentiating, relational descriptors Description Rate of cardiac beats Common Term Heart Rate Acronym HR

  4. ISO/IEEE 11073-10101 Topics of Note Discriminators support systematic extensions Base term MDC_ECG_HEART_RATE MDC_ECG_HEART_RATE_MIN MDC_ECG_HEART_RATE_MAX Base term MDC_ECG_ELEC_POTL_ST_60_V5 { 20, 40, 60, 80 } msec { I, II, V1, V2, V3, V4, V5, V6 … } ECG lead

  5. ISO/IEEE 11073-10101 Code Blocks Nomenclature is organized by 65K entry ‘blocks’

  6. ISO/IEEE 11073-10101 Block C: Metrics

  7. ISO/IEEE 11073-10101 Other blocks • Nomenclature Extensions • 11073-10102 “Annotated ECG” • FDA-HL7 “aECG” using HL7 V3 messaging, SCP-ECG/OpenECG and DICOM • 11073-10103 “Implanted Devices” • 11073-10104 “Virtual Attributes” for remote command/control

  8. Recommendations • Use ISO/IEEE 11073-10101 for xHR Device Data • Provides a structured and comprehensive nomenclaturefor vital signs devices and physiologic data • Covers all aspects of medical device communication • Provides single, consistent nomenclature framework • It is an ISO/IEEE International Standard (approved 2004) • Facilitates adoption by other countries and organizations • It used by X73_PH Personal Health Devices • Device, Compute Engine and xHR use same nomenclature • Simplifies gateway and proxy design • Aligned with related industry standard efforts, e.g. IHE PCD-01 Profile, using HL7 V2.X messaging
