Example Data Table
| Scenario | Weight | Inputs | Example Output | Notes |
|---|---|---|---|---|
| Pediatric Anaphylaxis | 18 kg | 1 mg/mL | 0.18 mg = 0.18 mL | IM/SC, thigh, repeat every 5 to 10 minutes if needed. |
| Adult Anaphylaxis | 72 kg | 1 mg/mL, selected 0.3 mg | 0.3 mg = 0.3 mL | Labeled adult range remains 0.3 to 0.5 mg. |
| Pediatric Cardiac Arrest | 24 kg | 0.1 mg/mL | 0.24 mg = 2.4 mL | IV/IO, repeat every 3 to 5 minutes. |
| Adult Septic Shock Infusion | 70 kg | 0.1 mcg/kg/min, 1 mg in 1000 mL | 7 mcg/min = 7 mL/hr | Adult infusion reference only. Titrate per protocol. |
Formula Used
How to Use This Calculator
- Choose the clinical scenario first. The page shows only the inputs relevant to that mode.
- Enter weight in kilograms whenever the selected mode needs weight-based dosing.
- For bolus modes, enter the exact concentration currently prepared at your site.
- For adult anaphylaxis, choose whether you want the display based on 0.3 mg or 0.5 mg.
- For infusion math, enter the bag drug amount, bag volume, and target rate in mcg/kg/min.
- Press Calculate Dose. The result appears above the form, directly below the header.
- Use the CSV button to save calculation fields or the PDF button to export the visible result card.
- Always cross-check the output with labeling, route, local emergency standards, and a qualified clinician before use.
FAQs
1. Does this calculator replace a medical order or emergency protocol?
No. It is a structured math aid. Medication selection, route, timing, concentration, and administration still require local policy, product labeling, and clinician review.
2. Why does adult anaphylaxis show a range instead of one fixed number?
Adult labeled anaphylaxis dosing is commonly presented as 0.3 to 0.5 mg. This page lets you display either common adult endpoint while still showing the full labeled range.
3. Why must I enter concentration for arrest and anaphylaxis modes?
The dose may be fixed or weight-based, but the volume depends on the actual prepared concentration. Entering concentration converts milligrams into milliliters.
4. What pediatric cap is used for anaphylaxis?
For the pediatric anaphylaxis mode under 30 kg, the page applies 0.01 mg/kg and limits the displayed single dose to 0.3 mg.
5. What pediatric cap is used for cardiac arrest?
The pediatric cardiac-arrest mode calculates 0.01 mg/kg and caps the displayed dose at 1 mg, then converts that dose to volume from your entered concentration.
6. How is the infusion pump rate calculated?
The calculator converts mcg/kg/min into mcg per hour, then divides by the bag concentration in mcg/mL. The result is the pump setting in mL/hr.
7. Can I use this page for custom bag strengths?
Yes. The infusion mode accepts any positive drug amount and total bag volume, then recalculates concentration and pump rate from those values.
8. Why is there a warning even after the calculator gives a result?
Epinephrine is high risk. A correct formula can still become unsafe if the wrong route, syringe strength, patient weight, or protocol is used.
