May also be expressed as a rate per unit of time e.g. 500 ml per 2 hours. Currently we do not specify a default of '1' in the denominator, but this is being discussed. Other examples: 200 mcg/min or 200 mcg/1 minute; 1 liter/8 hours.

definition:
  v: 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. Currently we do not specify a default of '1' in the denominator, but this is being discussed. Other examples: 200 mcg/min or 200 mcg/1 minute; 1 liter/8 hours.

comment:
  v: There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

  v: 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. Currently we do not specify a default of '1' in the denominator, but this is being discussed. Other examples: 200 mcg/min or 200 mcg/1 minute; 1 liter/8 hours.
