## Resource Profile: Average Blood Pressure

Official URL: http://hl7.org/fhir/us/vitals/StructureDefinition/average-blood-pressure | Version: 2.0.0
Draft as of 2024-10-09 | Computable Name: AverageBloodPressure
Copyright/Legal: Logica Health, all rights reserved Creative Commons License

A calculated average of two or more blood pressure readings in a specified time period or according to a specified algorithm or protocol. The average blood pressure has a systolic and a diastolic component.

### Scope

This blood pressure profile is used to capture the calculated average blood pressure from a set of individual measurements.

#### About the extensions

The expectation for the extensions in this profile is that if populated, they qualify each of the individual measurements used to calculate the average blood pressure. For example, if the body position give in an intance of the this profile is "sitting" then the body position for either the systolic or diastolic blood pressures is "sitting".

Body Position - This is used to capture an individual's body position while taking a blood pressure.

Exercise Association - This is used to capture an individual's excercise status while taking blood pressure.

Measurement Setting - This is used to capture the location (not body site) where the measurement(s) took place; At home, hospital, clinic, etc.

Measurement Protocol - This is used to capture a set of rules used for the calculation of the blood pressure average; the number of measurments to be obtained, the time interval between measurements, the overall period for the measurements, and any instructions such as "take while sitting, after five minutes", etc.. This can be institution specific, provider specific, clinical society specific (i.e. AMA), etc.

#### Example

AverageBloodPressure-example

#### Value Sets

Value Set | Purpose
--- | ---
Body Position value set | This value set contains concepts used to result the patient's body position, referencing the SNOMED Code 397155001 Body position (observable entity) and the LOINC term "Body position with respect to gravity" 8361-8.
Blood Pressure Device Type value set | This value set contains concepts used to result the type of device used to measure a body blood pressure, referencing the SNOMED Code 23591000205102 “Blood pressure device type (observable entity)" and the LOINC term “Type of Blood pressure device” 41901-0.
Blood Pressure Measurement Site value set | This value set contains a constrained list body location values used to result the body location where a blood pressure was measured, referencing the SNOMED Code 2281000205100 “Blood pressure measurement site (observable entity)” and the LOINC term "Blood pressure measurement site", 41904-4.
Blood Pressure Method value set | This value set contains concepts used to result the method used for a blood pressure measurement, referencing the SNOMED Code 2291000205103 “Blood pressure method (observable entity)” and the LOINC term "Blood pressure method" 8357-6.
Exertion Phase value set | The purpose of the value set is to document exercise associated with a measurement. Resulting LOINC code 74008-4 "Exercise intensity".
Sleep Status value set | This value set contains values used to indicate the state of wakefulness during measurement.
Measurement Setting value set | This value set is used to result the Measurement Setting extension.
