Optional normal range.

Optional tagged other reference ranges for this value in its particular measurement context.

Optional status of magnitude with values:

• '=' : magnitude is a point value
• '<' : value is < magnitude
• '>' : value is > magnitude
• '<=' : value is <= magnitude
• '>=' : value is >= magnitude
• '~' : value is approximately magnitude

If not present, assumed meaning is '=' .

Accuracy of measurement, expressed either as a half-range percent value (accuracy_is_percent = True) or a half-range quantity. A value of 0 means that accuracy is 100%, i.e. no error.

A value of unknown_accuracy_value means that accuracy was not recorded.

If True, indicates that when this object was created, accuracy was recorded as a percent value; if False, as an absolute quantity value.

Numeric magnitude of the quantity.

Precision to which the value of the quantity is expressed, in terms of number of decimal places. The value 0 implies an integral quantity. The value -1 implies no limit, i.e. any number of decimal places

Quantity units, expressed as a code or syntax string from either UCUM (the default) or the units system specified in units_system, when set.

In either case, the value is the code or syntax - normally formed of standard ASCII - which is in principal not the same as the display string, although in simple cases such as 'm' (for meters) it will be.

If the units_display_name field is set, this may be used for display. If not, the implementations must effect the resolution of the units value to a display form locally, e.g. by lookup of reference tables, request to a terminology service etc.

Example values from UCUM: 'kg/m^2', 'mm[Hg]', 'ms-1', 'km/h'

Optional field used to specify a units system from which codes in units are defined. Value is a URI identifying a terminology containing units concepts from the (HL7 FHIR terminologies list).

If not set, the UCUM standard (case-sensitive codes) is assumed as the units system.

Optional field containing the displayable form of the units field, e.g. '°C'.

If not set, the application environment needs to determine the displayable form.

The display name may be language-dependent for various older and non-systematic units. For this reason, it is not recommended to add unit display names to archetypes, only to templates (for localisation purposes).

Optional specific reason for null value; if set, null_flavour must be set. Null reason may apply only to a minority of clinical data, commonly needed in reporting contexts.

• '>=' : value is >= magnitude
• '~' : value is approximately magnitude

If not present, assumed meaning is '=' .

Accuracy of measurement, expressed either as a half-range percent value (accuracy_is_percent = True) or a half-range quantity. A value of 0 means that accuracy is 100%, i.e. no error.

A value of unknown_accuracy_value means that accuracy was not recorded.

If True, indicates that when this object was created, accuracy was recorded as a percent value; if False, as an absolute quantity value.

Numeric magnitude of the quantity.

Precision to which the value of the quantity is expressed, in terms of number of decimal places. The value 0 implies an integral quantity. The value -1 implies no limit, i.e. any number of decimal places

Quantity units, expressed as a code or syntax string from either UCUM (the default) or the units system specified in units_system, when set.

In either case, the value is the code or syntax - normally formed of standard ASCII - which is in principal not the same as the display string, although in simple cases such as 'm' (for meters) it will be.

If the units_display_name field is set, this may be used for display. If not, the implementations must effect the resolution of the units value to a display form locally, e.g. by lookup of reference tables, request to a terminology service etc.

Example values from UCUM: 'kg/m^2', 'mm[Hg]', 'ms-1', 'km/h'

Optional field used to specify a units system from which codes in units are defined. Value is a URI identifying a terminology containing units concepts from the (HL7 FHIR terminologies list).

If not set, the UCUM standard (case-sensitive codes) is assumed as the units system.

Optional field containing the displayable form of the units field, e.g. '°C'.

If not set, the application environment needs to determine the displayable form.

The display name may be language-dependent for various older and non-systematic units. For this reason, it is not recommended to add unit display names to archetypes, only to templates (for localisation purposes).

Optional specific reason for null value; if set, null_flavour must be set. Null reason may apply only to a minority of clinical data, commonly needed in reporting contexts.

The average arterial pressure that occurs over the entire course of the heart contraction and relaxation cycle.

This is the term provided via a clinical application or batch process to name this EHR construct: its retention in the EHR faithfully preserves the original label by which this entry was known to end users.

Design-time archetype identifier of this node taken from its generating archetype; used to build archetype paths. Always in the form of an at-code, e.g. at0005. This value enables a 'standardised' name for this node to be generated, by referring to the generating archetype local terminology.

At an archetype root point, the value of this attribute is always the stringified form of the archetype_id found in the archetype_details object.

Optional globally unique object identifier for root points of archetyped structures.

Links to other archetyped structures (data whose root object inherits from ARCHETYPED, such as ENTRY, SECTION and so on). Links may be to structures in other compositions.

Details of archetyping used on this node.

Audit trail from non-openEHR system of original commit of information forming the content of this node, or from a conversion gateway which has synthesised this node.

Flavour of null value, e.g. 253|unknown|, 271|no information|, 272|masked|, and 273|not applicable|.

Property representing leaf value object of ELEMENT. In real data, any concrete subtype of DATA_VALUE can be used.

Optional normal status indicator of value with respect to normal range for this value. Often included by lab, even if the normal range itself is not included. Coded by ordinals in series HHH, HH, H, (nothing), L, LL, LLL; see openEHR terminology group normal_status.

Optional normal range.

Optional tagged other reference ranges for this value in its particular measurement context.

Optional status of magnitude with values:
