If the rate is intended to change over time, depending on local rules/regulations, each change should be 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 grammer 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." /> <requirements value="Identifies the speed with which the medication was or will be introduced into the patient. Typically the rate for an infusion e.g. 100 ml per 1 hour or 100 ml/hr. May also be expressed as a rate per unit of time e.g. 500 ml per 2 hours. Other examples: 200 mcg/min or 200 mcg/1 minute; 1 liter/8 hours. Sometimes, a rate can imply duration when expressed as total volume / duration (e.g. 500mL/2 hours 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 time period." /> <min value="0" /> <max value="1" /> <base> <path value="Dosage.doseAndRate.rate[x]" /> <min value="0" /> <max value="1" /> </base> <type> <code value="Ratio" /> </type> <type> <code value="Range" /> </type> <type> <code value="Quantity" /> </type> <isModifier value="false" /> <isSummary value="true" /> <mapping> <identity value="v2" /> <map value="RXE22, RXE23, RXE-24" /> </mapping> <mapping> <identity value="rim" /> <map value=".rateQuantity" /> </mapping> </element> </snapshot> </StructureDefinition>
