Resource Profile: US Core Blood Pressure Profile

US Core Blood Pressure Profile inherits from the US Core Vital Signs Profile. This profile sets minimum expectations for the Observation resource to record, search, and fetch diastolic and systolic blood pressure observations with standard LOINC codes and UCUM units of measure. It specifies which additional core elements, extensions, vocabularies, and value sets SHALL be present in the resource and constrains how the elements are used. Providing the floor for standards development for specific use cases promotes interoperability and adoption.

Usage:

• This Resource Profile is not used by any profiles in this Implementation Guide
