2016-10-24--26 - OBSERVABLE Meeting

• Remember recording!

• Check GotoMeeting number before next session

1. None declared

• If needed

• See attached slide deck
• Review of the document IHTSDO-979 Vital Signs Observables and the ontology available here.
• Should there be a vital signs concept or a refset? See discussion here.

Recommendations

1. The Observables group recommended that due to ambiguity in what is classed as a Vital Sign, that the Vital Sign grouper be retired. Users who want to group vital signs can use the Ref Set Mechanism.

2. That all non-aggregate Vital Signs should be time aspect "Single point in time." The decision changed later in the meeting to "Do not add the time aspect unless it is clear that the observable is Point in Time."
   Noted: Jim Campbell and Scott Campbell opposed this and Mary and Raj abstained form the vote.

3. Retire “peripheral body temperature” to navigational concepts.

4. Heart Rate and Respiratory rate processes (Check with Daniel K regarding this recommendation). The names put forward were recommended by the group, unopposed.

5. Blood pressure model. There where two possible valid models proposed.
   
   1. Inhere in the cardiovascular structure
   2. Inhere in the fluid, with inherent location the vascular system.
      The group recommended that model should be a) however it was noted that should multiple sufficient sets be implemented, then both versions of blood pressure could be used. 
6. Heart rate:

   The group resolved to use "arteries" for the direct site of the pulse

7. The version of the model for Peripheral Oxygen Saturation that was proposed by Daniel Karlsson was recommended (unopposed.)

8. The version of the model for Ankle brachial pressure index was recommended (unopposed)
