Blood gas partial pressure mapping for mmHg and kPa

Legacy laboratory-loinc chemistry
1

It was found that LOINC does not have suggested unit kPa for blood gas related tests. Should it be mapped with those LOINC code with suggesting unit= mmHg?

 

Thanks

Hello! You are correct, both the SI derived unit of measure for pressure, the Pascal unit and the routinely used (but not SI based) millimeter of mercury (mmHg) measure a gas from a pressure stand point.

The property attribute you would be seeking for each gaseous analyte is PPRES

Thank you for asking,

Thanks pdbanning~ Hope that LOINC can include SI and non-SI unit as example unit in the future.

Any guidline for LOINC code mapping to partial pressure reporting with Pascal unit?
