Profiles

Profiles

This page lists the StructureDefinition profiles defined in the Lithuanian Vital Signs Implementation Guide. Use them to ensure consistent representation of vital signs and anthropometric data across systems.

Why these profiles matter

• For implementers and reporting: Standardised profiles enable interoperable exchange between devices, EHRs, and national or regional repositories. Consistent structure and bindings support aggregation, analytics, and reuse of vital signs data without custom mappings.
• For clinicians: Profiles encode required observation codes (LOINC, SNOMED CT), units (UCUM), and optional context (body position, device, measurement setting). This supports accurate data capture, calculation of derived values (e.g. BMI), and reliable use in decision support and care pathways.

Observation profiles

Profile	Purpose
Blood Pressure Panel	Groups systolic, diastolic, and optional mean arterial pressure with method, body location, and device context.
Heart Rate	Pulse measurement with optional body location and method.
Body Height	Body length/height in standard units (e.g. cm).
Body Weight	Body mass with optional associated situation (e.g. dressed, after dialysis).
BMI	Body mass index for obesity and metabolic risk assessment.
Head Circumference	Head circumference for paediatric and growth assessment.
Waist Circumference	Waist circumference for metabolic and cardiovascular risk.

Device profiles

Profile	Purpose
Device Blood Pressure	Blood pressure monitor; reference from observations when device is known.
Device Body Height	Device used for height/length measurement.
Device Body Weight	Scale or device for body weight.
Device Heart Rate	Heart rate measurement device.

Body Structure

Profile	Purpose
Body Structure Blood Pressure	Anatomical site for blood pressure measurement (e.g. arm); reference from observation when site is modelled as a separate resource.

Extensions

Extensions add context that may not be precoordinated in the observation code:

Extension	Purpose
body-position	Body position during measurement (e.g. sitting, standing).
sleep-status	Sleep/awake status at time of measurement.
exercise-association	Association with exercise (e.g. exertion phase).
measurement-setting	Setting (e.g. ambulatory, home).
associated-situation	Qualifying situation (e.g. body weight when dressed, after dialysis).
