    Description

      The current vitalsing profile only allows 12 UCUM units on Observation.component.valueQuantity. This is a problem in down-stream use-cases: e.g.: in Germany OxygenSaturation in some use-cases uses components to transport the oxygen flowrate which was present during measurement.
      As the vitalsigns profiles are restricting the usable ucum codes on observation.component.value to the minimal 12 ucum VS, and flowrate is measured in L/min several projects are running into validation issues.
