Vital Signs with Qualifying Elements
1.0.0 - STU 1 US

This page is part of the Vital Signs FHIR IG (v1.0.0: STU1) based on FHIR R4. This is the current published version in its permanent home (it will always be available at this URL). For a full list of available versions, see the Directory of published versions



The following Profiles and have been defined for this implementation guide.

Profile Definition
Vital Signs Panel A vital signs panel as defined by Logica Health. It includes Oxygen Saturation via Pulse Oximetry, Oxygen Saturation in Arterial blood, body height, body length, body weight, body temperature, blood pressure panel, heart rate, respiratory rate, head-occipital/frontal circumference, oxygen saturation via pulse oximetry, and body mass index.
Blood Pressure Panel Blood Pressure Panel; a grouping of systolic, diastolic, and mean arterial blood pressure components.
Average Blood Pressure 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.
Twenty Four Hour Blood Pressure An average blood pressure (systolic and diastolic) over a twenty four hour period.
Blood Pressure Device A profile of the Device resource used specifically for blood pressure devices and includes an extension for blood pressure cuff size.
Body Height The measurement in centimeters or feet and inches from the top of the head to the heel, usually while standing.
Body Length The measurement in centimeters or inches from the top of the head to bottom of the heel, taken while lying down.
Body Mass Index A numerical index based on an individual's weight in kilograms divided by the square of their height in meters.
Body Temperature The measured heat of an individual's body.
Body Weight The measured mass of an individual's body.
Head Occipital Frontal Circumference The measured length around and individual's head via a tape measure using the frontal-occipital plane.
Heart Rate The number of heart beats in a minute.
Oxygen Saturation in Arterial Blood by Pulse Oximetry A measurement of the percentage to which oxygen is bound to hemoglobin in arterial blood via pulse oximetry.
Oxygen Saturation in Arterial blood, method not specified A measurement of the percentage to which oxygen is bound to hemoglobin in arterial blood.
Respiratory Rate The measured number of breaths taken in a minute.


The following extensions have been defined as part of the Vital Signs implementation Guide. A registry of standard extensions can be found in the FHIR specification and additional extensions may be registered on the HL7 FHIR registry at

A note about value bindings in the extensions

Some of the extensions defined below do not have value set bindings included. This is because the extension may be used in more than one profile and the values needed are specific to the context of the containing profile. For example, the Associated Situation extension is used in both the Body Temperature profile as well as the Body Weight profile. The values for Associated Situation will differ between these two contexts. For Body Temperature the values are things like “post exercise” but for Body Weight they’re things like “With prosthetic” or “undressed”.
