  3. IHE Device Enterprise Communication (DEC) and related Profiles (PCD, SPD, ACM). Device Observation Consumer (DOC) PCD-01 Transaction: Communicate Device Data • ISO/IEEE 11073-10101 nomenclature (does not rule out LOINC or SNOMED) • ISO/IEEE 11073 or UCUM units-of-measure • OBX-4 used for «mds.vmd.chan.metric», OBX-20 for measurement sites • Profile and simplify other aspects of HL7 V2.5 messaging • Periodic Physiologic Data: Heart Rate, Respiration rate • Episodic Physiologic Data: NIBP, Weight, Cardiac tests • Primarily structured data but facilities non structured data as well • Must include Patient ID • > 1 minute sampling rate (but could be faster) • Waveform support is simple extension • Flexible extensions with: • Alarms and alerts supported through related profile (ACM) • Subscribe to Patient Data (SPD) Profile • Security, privacy, confidentiality through related profile (ATNA) Device Observation Reporter (DOR) Device

  4. Mapping Preserves Measurement Context Overall Device or System Virtual Medical Device Channel (only as needed) A single observation

  7. IHE DEC (and associated) profiles • Provides a Unified Interface that -- • Supports the complete range of device data (except for high-bandwidth continuous waveforms) found in health related devices today and in the future. • Provides a consistent interface in Health Record, CareManagement Systems and Personal Health Records that is: • Secure, private • High performance even on low bandwidth links • Scalable, from a simple device intermediary (a few devices for the same patient) to multiple devices for many patients. Trivial to implement. • Straightforward mapping from proprietary and IEEE 11073 formats (uses same nomenclature as X73 Personal Health devices). • Based on proven HL7 standards that are supported by all Care Management and EHRs products today
