PCD-01 Transaction: Communicate Device Data
• 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)
• 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

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
