Use to record all representations of systemic arterial blood pressure measurement, no matter which method or body location is used to record it. The archetype is intended to capture blood pressure measurements in all clinical scenarios - for example: - self-measurement with a home blood pressure machine; - an emergency assessment of systolic using palpation and a sphygmomanometer; - measurements taken in clinical consultations or during exercise stress testing; and - a series of measurements made by a machine in Intensive Care. There is a rich state model that supports interpretation of measurements through identifying patient position, exercise, confounding factors and angle of a tilt table in research. Named events have been limited to average over a 24 hour period, however templates can further constrain the default 'any event' to cater for specific requirements for blood pressure measurements such as recording Blood Pressure against specific points in time, or over a range of intervals (+/- mathematical functions).
To record the systemic arterial blood pressure of an individual. Misuse: Not to be used to record the measurement of arterial blood pressure which is NOT a surrogate for arterial pressure in the systemic circulation eg specific measurement of right pulmonary artery pressure. Use OBSERVATION.intravascular_pressure in this situation. Not to be used to record measurements of intravenous pressure. Use the appropriate specialisations of OBSERVATION.intravascular_pressure in this situation.

Accuracy of measurement, expressed either as a half-range percent value (accuracy_is_percent = True) or a half-range quantity
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
If True, indicates that when this object was created, accuracy was recorded as a percent value; if False, as an absolute quantity value.
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
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'
URI identifying a terminology containing units concepts (from the FHIR terminologies list). UCUM is default
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'
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).
