Alternatively if the dose was 375 mg, then you may only need to use the Medication resource to indicate this was a tablet. If the example were an IV such as dopamine and you wanted to communicate that 400mg of dopamine was mixed in 500 ml of some IV solution, then this would all be communicated in the Medication resource. If the administration is not intended to be instantaneous (rate is present or timing has a duration), this can be specified to convey the total amount to be administered over the period of time as indicated by the schedule e.g. 500 ml in dose, with timing used to convey that this should be done over 4 hours." /> <requirements value="The amount of therapeutic or other substance given at one administration event." /> <min value="0" /> <max value="1" /> <base> <path value="Dosage.doseAndRate.dose[x]" /> <min value="0" /> <max value="1" /> </base> <type> <code value="Range" /> </type> <type> <code value="Quantity" /> <profile value="http://hl7.org/fhir/StructureDefinition/SimpleQuantity" /> </type> <condition value="ele-1" /> <constraint> <key value="ele-1" /> <severity value="error" /> <human value="All FHIR elements must have a @value or children" /> <expression value="hasValue() or (children().count() > id.count())" /> <xpath value="@value|f:*|h:div" /> <source value="http://hl7.org/fhir/StructureDefinition/Element" /> </constraint> <isSummary value="true" /> <mapping> <identity value="rim" /> <map value="n/a" /> </mapping> <mapping> <identity value="v2" /> <map value="RXO-2, RXE-3" /> </mapping> <mapping> <identity value="rim" /> <map value=".doseQuantity" /> </mapping> </element> <element id="Dosage.doseAndRate.rate[x]"> <path value="Dosage.doseAndRate.rate[x]" /> <short value="Amount of medication per unit of time" /> <definition value="Amount of medication per unit of time." /> <comment value="It is possible to supply both a rate and a doseQuantity to provide full details about how the medication is to be administered and supplied. 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.
