Just to concur with Heath. These are intended to describe the clinical assumption that it would be safe to make, usually about patient state, if the data was NOT specifically recorded. i.e if patient position was not recorded in a blood pressure reading, it would be safe to assume the patient was sitting, or if the oxygen level was not recorded in the ambient oxygen archetype, it would be safe to assume that the patient was breathing air.
In practice, we have very few examples in the CKM archetypes to date, where it is safe to make such clinical assumptions.
