    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?

    Regards,

    Barry
