Active as of 2023-01-16

Definitions for the IVL-PQ logical model.

Guidance on how to interpret the contents of this table can be found here.

1. IVL_PQ
Control1..*
XML RepresentationIn the XML format, this property has the namespace urn:hl7-org:v3.
2. IVL_PQ.unit
Definition

The unit of measure specified in the Unified Code for Units of Measure (UCUM) [].

Control0..1
Typecode
XML RepresentationIn the XML format, this property is represented as an attribute.
3. IVL_PQ.value
Definition

The magnitude of the quantity measured in terms of the unit.

Control0..1
Typedecimal
XML RepresentationIn the XML format, this property is represented as an attribute.
4. IVL_PQ.low
Definition

This is the low limit of the interval.

Control0..1
Typehttp://hl7.org/fhir/cda/StructureDefinition/PQ
5. IVL_PQ.high
Definition

This is the high limit of the interval.

Control0..1
Typehttp://hl7.org/fhir/cda/StructureDefinition/PQ
6. IVL_PQ.width
Definition

The difference between high and low boundary. The purpose of distinguishing a width property is to handle all cases of incomplete information symmetrically. In any interval representation only two of the three properties high, low, and width need to be stated and the third can be derived.

Control0..1
Typehttp://hl7.org/fhir/cda/StructureDefinition/PQ
7. IVL_PQ.center
Definition

The arithmetic mean of the interval (low plus high divided by 2). The purpose of distinguishing the center as a semantic property is for conversions of intervals from and to point values.

1. IVL_PQ
Definition

Defines the basic properties of every data value. This is an abstract type, meaning that no value can be just a data value without belonging to any concrete type. Every concrete type is a specialization of this general abstract DataValue type.

Base definition for all types defined in FHIR type system.
