The official URL for this profile is:

http://hl7.org/fhir/StructureDefinition/devicemetricobservation

This profile describes the direct or derived, qualitative or quantitative physiological measurement, setting, or calculation data produced by a medical device or a device component.

This profile was published on Mon, Nov 17, 2014 00:00+1100 as a draft by Health Level Seven International (Health Care Devices).

Description of Profiles, Differentials, Snapshots, and how the XML and JSON presentations work.

This structure is derived from Observation.
