ValueSet: ActControlVariable

Summary

Defining URL:http://terminology.hl7.org/ValueSet/v3-ActControlVariable
Version:2.0.0
Name:ActControlVariable
Status:Active as of 2014-03-26
Definition:

An observation form that determines parameters or attributes of an Act. Examples are the settings of a ventilator machine as parameters of a ventilator treatment act; the controls on dillution factors of a chemical analyzer as a parameter of a laboratory observation act; the settings of a physiologic measurement assembly (e.g., time skew) or the position of the body while measuring blood pressure.

Control variables are forms of observations because just as with clinical observations, the Observation.code determines the parameter and the Observation.value assigns the value. While control variables sometimes can be observed (by noting the control settings or an actually measured feedback loop) they are not primary observations, in the sense that a control variable without a primary act is of no use (e.g., it makes no sense to record a blood pressure position without recording a blood pressure, whereas it does make sense to record a systolic blood pressure without a diastolic blood pressure).

AUTOauto-repeat permissionSpecifies whether or not automatic repeat testing is to be initiated on specimens.
ENDCendogenous contentA baseline value for the measured test that is inherently contained in the diluent. In the calculation of the actual result for the measured test, this baseline value is normally considered.
REFLEXreflex permissionSpecifies whether or not further testing may be automatically or manually initiated on specimens.

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies

Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
