IV Insulin Infusion Monitoring Tool

Track glucose trends and document infusion details accurately. Export records quickly for audits, handoffs, and safer reviews.

Hospital workflow support

This page helps document bedside insulin infusion monitoring, glucose movement, bag concentration, estimated bag duration, and trend charts. It intentionally does not generate or recommend a treatment rate. Use your organization’s insulin infusion protocol for all dosing decisions.

Monitoring Summary

Important: Insulin is a high-alert medication. Confirm orders, concentration, units, pump settings, and institutional protocol before any bedside action.

Glucose Trend Graph

The chart visualizes entered glucose values and target bounds to support review during rounds, handoff, and documentation.

Example Data Table

Check Time	Blood Glucose	Current Pump Rate	Bag Concentration	Estimated Bag Hours Left	Comment
07:00	340 mg/dL	4.0 U/hr	1.00 U/mL	15.0 hr	Admission sample; protocol review completed.
08:00	312 mg/dL	4.0 U/hr	1.00 U/mL	14.0 hr	Glucose trending down; continue monitoring.
09:00	286 mg/dL	4.0 U/hr	1.00 U/mL	13.0 hr	No protocol change shown here.
10:00	248 mg/dL	4.0 U/hr	1.00 U/mL	12.0 hr	Approaching range; verify electrolytes and dextrose plan.

Formula Used

This tool avoids any formula that recommends insulin dose adjustments. Instead, it calculates neutral monitoring values:

Glucose change = Current glucose − Previous glucose
Hourly glucose change = (Current glucose − Previous glucose) ÷ Hours between checks
Bag concentration = Bag insulin units ÷ Bag volume in mL
mL per hour delivered = Current units per hour ÷ Concentration
Estimated bag hours left = Remaining bag volume ÷ Delivered mL per hour
Range status compares current glucose with target low and high values

Any insulin titration must follow the clinician’s order set and facility-approved infusion protocol.

How to Use This Calculator

Enter the current and previous blood glucose values.
Enter the interval between checks in hours.
Enter target range, current pump rate, and bag details.
Add dextrose and electrolyte context for monitoring notes.
Optionally enter a recent glucose series for charting.
Press the button to generate a monitoring summary.
Review neutral metrics like trend, concentration, and bag duration.
Use your institutional protocol for any infusion adjustment.
Export CSV or PDF for charting, audit, or shift handoff.

Frequently Asked Questions

1. Does this page recommend an insulin infusion rate?

No. It documents glucose trends, bag concentration, and neutral monitoring metrics only. Any rate change must come from your hospital’s approved insulin infusion protocol and clinician judgment.

2. Why avoid automatic dose adjustment here?

Insulin is a high-alert medicine. Incorrect automated dosing logic can cause severe hypoglycemia, electrolyte problems, delayed correction, or other dangerous bedside errors.

3. What is bag concentration used for?

Bag concentration converts insulin units to delivered milliliters per hour. That helps estimate remaining bag duration and supports pharmacy, nursing, and pump documentation.

4. Can I use mmol/L instead of mg/dL?

This template is labeled for mg/dL. You can adapt the labels and inputs for mmol/L, but keep units consistent everywhere to avoid documentation errors.

5. What does hourly glucose change show?

It estimates how fast glucose is moving between two measurements. That trend supports review, but it is not a substitute for a treatment protocol.

6. Can this tool be used for DKA workflows?

It may help document DKA monitoring inputs, such as glucose and anion gap, but it should never replace approved order sets, clinician assessment, or protocolized care.

7. What should I include in the glucose series field?

Enter recent values in chronological order, separated by commas. Use matching time points in the hours-ago field so the chart plots each result correctly.

8. What exports are included?

The page supports CSV export for spreadsheet review and PDF export for printing or record handoff. Both exports use the current visible monitoring summary.
