Re: DV_PROPORTION vs DV_QUANTITY for %

2019-01-14 Thread Ian McNicoll 
Sorry - the reason is that O2% is also described as FIO2 which is directly
mathematically equivalent.

FiO₂
Proportion
Optional

Fraction of oxygen in inspired air.
Comment: For example: '0.28'.

Unitary

Numerator: 0.0..1.0
Percent O₂
Proportion
Optional
Percentage of oxygen in inspired air.
Comment: For example: '24 %'

Percent

Numerator: 0.0..100.0

Re: DV_PROPORTION vs DV_QUANTITY for %

2019-01-14 Thread Diego Boscá 
As far as I understand in oxygen levels the denominator is not 100 but a
quantity, and that denominator may vary. I don't know how it is measured in
alcohol, but probably % of alcohol in blood assuming always the same
quantity to get the percentage?
I'm not really sure anyway :)

I still don’t understand if we have a conclusion. And I don’t understand why 
proportion is the correct data type for O2 levels but not for alcohol levels.

Simple answer - loads of real data - pulse_oximetry and Oxygen levels will have 
been recorded hundreds of thousands if not millions of times in patient data - 
and Proportion *is* the correct datatype for O2 levels.
