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).

This value set contains 4 concepts

SystemCodeDisplay (en)InactiveDefinitionJSONXML
http://terminology.hl7.org/CodeSystem/v3-ActCode  AUTOauto-repeat permission

Specifies whether or not automatic repeat testing is to be initiated on specimens.

http://terminology.hl7.org/CodeSystem/v3-ActCode  ENDCendogenous content

A 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.

Specifies whether or not further testing may be automatically or manually initiated on specimens.
