       with a new MedicationRequest with the new rate.

It is possible to specify a rate over time (for example, 100 ml/hour) using either
       the rateRatio and rateQuantity.  The rateQuantity approach requires systems to
       have the capability to parse UCUM grammar where ml/hour is included rather than
       a specific ratio where the time is specified as the denominator.  Where a rate
       such as 500ml over 2 hours is specified, the use of rateRatio may be more semantically

       all be communicated in the Medication resource. If the administration is not intended

       captured as a new version of the MedicationRequest with an updated rate, or captured
       with a new MedicationRequest with the new rate.

It is possible to specify a rate over time (for example, 100 ml/hour) using either
       the rateRatio and rateQuantity.  The rateQuantity approach requires systems to
       have the capability to parse UCUM grammar where ml/hour is included rather than
       a specific ratio where the time is specified as the denominator.  Where a rate
       such as 500ml over 2 hours is specified, the use of rateRatio may be more semantically
       correct than specifying using a rateQuantity of 250 mg/hour."/>

       implies a duration of 2 hours).  However, when rate doesn't imply duration (e.g.
       250mL/hour), then the timing.repeat.duration is needed to convey the infuse over
