IV Drip Rate Calculator (Gravity)
Calculate the gravity (manual) IV drip rate in drops per minute: gtt/min = Volume × Drop factor / Time. Drop factor selectable (macro 10/15/20 or micro 60 gtt/mL). Time may be hours+minutes or minutes; rounded to whole drops with drift warning. Vasoactive/cardiotonic drugs and pediatric infusions must ALWAYS use a pump. Derived from Philips 2007, Macklin 2011, MDCalc, and ISMP. Not medical advice.
Quick start
Call this tool from your code in three languages.
curl -X POST 'https://api.elysiatools.com/en/api/tools/iv-drip-rate-calculator' \
-H 'Content-Type: application/json' \
-d '{"dropFactor":"20","volume":1000,"hours":4,"minutes":0,"decimalPlaces":1}'API reference
Send a POST request with your inputs as JSON. File parameters require a separate upload first.
Endpoint
POST https://api.elysiatools.com/en/api/tools/iv-drip-rate-calculatorParameters
| Name | Type | Required | Description |
|---|---|---|---|
