- FLOW RATES
- Total Volume to Infuse (mL) X Drop Factor/ Time in Minutes = Drops/Minute (gtt/min)
- INFUSION TIME
- Total Volume to Infuse / mL per Hour Being Infused = Infusion Time
- Number of mL/Hr
- Total Volume in mL / Time in Hours = Number of mL per Hour

Infusions Prescribed by Unit Dosage per Hour
- Step 1
- Determine Amount of Medication per 1mL
- Known Amount of Medication in Solution/Total Volume of Diluent = Amount of Medication per Milliliter
- Step 2
- Calculate mL per Hour
- Dose per Hour Desired/Concentration per Milliliter = Infusion Rate (mL/hour)
