I think this is getting closer to a viable solution. Keep the text in each translation relevant to the typical local situation, but acknowledge all equivalent values/units in the ordinal value description.
Maybe a slight refinement for the English version:
0: PaO2/FiO2 ≥ 400 mmHg [The partial pressure of oxygen in arterial or capillary blood measured in mmHg, divided by the fraction of inspired oxygen is greater than or equal to 400 mmHg. Equivalent to PaO2/FiO2 ≥ 53 kPa. ]
And the Norwegian version:
0: PaO2/FiO2 ≥ 53 kPa. [The partial pressure of oxygen in arterial or capillary blood measured in kPa, divided by the fraction of inspired oxygen is greater than or equal to 53 kPa. Equivalent to PaO2/FiO2 ≥ 400 mmHg. ]
- Assumes equivalency of the values, or else it does require different archetypes.
- Could also be extended with additional units as required, although it will be messy. But then clinical medicine is often messy
