Vital signs

Approximately 150 physiological measurement observable entity concepts including body temperature, respiratory rate, heart rate, and blood pressure concepts were modeled for the January 2017 International release of SNOMED CT. This modeling work was based on the IHTSDO-979 Vital Signs Observables Inception/Elaboration document (linked above). Note that the concept 46680005|Vital sign (observable entity) has been inactivated as it was agreed that it cannot be reproducibly understood. A refset-based approach was proposed to replace the concept to specify lists of vital signs per use case.
