Concepts

This case-sensitive code system http://terminology.hl7.org/v2plusvocab/CodeSystem/tqConjunctionIdV110 defines the following codes:

CodeDisplayDefinitionversion introducedusage
A Asynchronous Asynchronous 2.4 Do the next specification in parallel with this one (unless otherwise constrained by the following components: ORC-7^4-start date/time and ORC-7^5-end date/time). The conjunction of _A_ specifies two parallel instructions, as are sometimes used in medication, e.g., prednisone given at 1 tab on Monday, Wednesday, Friday, and at 1/2 tab on Tuesday, Thursday, Saturday, Sunday.
C Actuation Time Actuation Time 2.4 ^1^QAM^X3^D10
S Synchronous Synchronous 2.4 An _S_ specification implies that the second timing sequence follows the first, e.g., when an order is written to measure blood pressure Q15 minutes for the 1st hour, then every 2 hours for the next day.
