Example Data Table

These rows illustrate typical planning scenarios.

Scenario Inputs Expected Output
Volume over time 240 mL over 4 hours, 2 mg/mL 60 mL/hr, 120 mg/hr, 480 mg total
Dose based infusion 70 kg, 5 mcg/kg/min, 1 mg/mL 21.00 mL/hr pump setting
Known rate over time 35 mL/hr for 6 hours, 0.5 mg/mL 210 mL total, 17.5 mg/hr

Formula Used

  • Flow rate: Rate (mL/hr) = Total Volume (mL) ÷ Time (hr)
  • Total volume: Volume (mL) = Rate (mL/hr) × Time (hr)
  • Dose conversion: mg/hr = mcg/kg/min × Weight × 60 ÷ 1000
  • Dose based pump rate: Rate (mL/hr) = Required Dose (mg/hr) ÷ Concentration (mg/mL)
  • Drug amount: Total Drug (mg) = Concentration (mg/mL) × Delivered Volume (mL)
  • Gravity drip estimate: Drops/min = Rate (mL/hr) × Drip Factor ÷ 60
  • Weight normalized view: mcg/kg/min = mg/hr × 1000 ÷ Weight ÷ 60

How to Use This Calculator

  1. Select a calculation mode that matches your known values.
  2. Enter total volume and time for direct rate planning.
  3. Enter flow rate and time for delivery forecasting.
  4. Use dose mode for weight based or fixed dose inputs.
  5. Enter concentration so the tool can convert dose to volume.
  6. Set drip factor if you want a gravity estimate.
  7. Optional safety limits flag unusually low or high settings.
  8. Press calculate to view the result, table, and chart.
  9. Use CSV or PDF export to save the output.

FAQs

1. What does this calculator determine?

It calculates pump rate, delivery time, total volume, dose conversion, and drip estimate from the values you provide.

2. Which calculation mode should I choose?

Choose volume over time when volume and duration are known. Choose known rate over time when the rate is fixed. Choose dose based infusion when the order depends on concentration and dose.

3. Why is concentration important?

Concentration links the required drug amount to actual liquid flow. Without concentration, a dose cannot be converted into a pump setting.

4. What units are supported?

The tool supports minutes, hours, days, mL, mL/hr, mg/mL, mcg/mL, mg/hr, mcg/min, mg/kg/hr, and mcg/kg/min.

5. What is the drip factor result for?

It converts a pump rate into an approximate gravity flow count. This helps compare pumped delivery with manual drip setups.

6. What do the safety limits do?

They create a planning band. The result will show whether the calculated rate falls below, within, or above your entered range.

7. Why is there a Plotly chart?

The chart shows cumulative delivered volume over time. It helps users understand delivery progress and spot unrealistic timing assumptions faster.

8. Can I use this result without checking anything else?

No. Use the page for planning and validation support only. Always verify final settings against your official protocol and equipment rules.
