Learning outcomes
What you will learn
- Explain the difference between mL/hr, mg/hr and mg/min in plain English.
- Find or use a concentration in mg/mL.
- Calculate mg/hr from mg/mL and a matching current mL/hr value.
- Convert mg/hr to mg/min and mg/min to mg/hr.
- Confirm the concentration and mL/hr belong to the same current infusion state, and stop if required values conflict or are unclear.
- Keep medication dose-rate units separate from volumetric infusion-rate fields on an infusion pump.
- Keep a medication rate separate from a total medication amount in mg.
Clinical connection
Why this matters
mL/hr, mg/hr and mg/min can appear in the same question. Keeping the unit beside every number makes it much harder to mistake the pump's fluid rate for the medication rate.
