Resource for oxygen administration

What is the best resource for oxygen administration?

I want to represent information about oxygen flow rate and concentration, start and change times, and oxygen administration routes (e.g., oxygen mask).

I am wondering if the Procedure resource is suitable, but I am troubled by the fact that it is often managed in the EMR together with information related to vital signs such as consciousness level.

I’ve referred this for discussion by the Patient Care WG. Short answer is “no official answer as yet”, but hoping to push the discussion to the point where we have a more official answer ‘soon’. If you want to monitor/participate in the discussion, you can do so here: https://chat.fhir.org/#narrow/stream/294552-Patient-Care.20WG/topic/Oxygen
