description: This profile defines a set of constraints to the FHIR Observation (HeadCircumference) resource for use in Alberta Patient Summaries (PS-AB). It re-profiles the HL7 FHIR HeadCircumference Profile and refines constraints applied to the Observation (HeadCircumference) resource when used in the PS-AB Composition profile.
