Frequently Asked Questions
What is a drop factor?
Drop factor describes how many drops from a specific IV tubing set equal one milliliter — it varies by tubing type, with macrodrip sets commonly at 10, 15, or 20 drops per mL and microdrip sets at 60 drops per mL, printed on the tubing packaging.
When is manual drip rate calculation still used given modern infusion pumps?
While electronic infusion pumps are standard in most modern clinical settings, manual gravity-fed calculation remains an important skill for situations without pump access and for verifying pump settings.
Why does microdrip tubing use a higher drop factor?
Microdrip tubing produces smaller drops, requiring more drops to deliver the same volume, which allows for more precise control at slower infusion rates, commonly used for pediatric patients or medications requiring very controlled delivery.
