Enter the volume and drop factor into the calculator to determine the Gtts per minute. This calculator can also evaluate any of the variables given the others are known.

## Gtts Per Minute Formula

The following formula is used to calculate the Gtts per minute.

GPM = (V * DF) / T

Variables:

- GPM is the Gtts per minute V is the volume in milliliters (ml) DF is the drop factor (gtts/ml) T is the time in minutes (min)

To calculate the Gtts per minute, multiply the volume in milliliters by the drop factor. Then divide the result by the time in minutes.

## What is a Gtts Per Minute?

Gtts per minute, also known as drops per minute, is a measurement used in medical treatments, particularly in intravenous therapy, to calculate the drip rate of intravenous fluids or medication. It is crucial in ensuring the patient receives the correct dosage over the appropriate period. The calculation takes into account the volume of fluid, the time over which it should be administered, and the drop factor of the specific IV tubing.

## How to Calculate Gtts Per Minute?

The following steps outline how to calculate the Gtts Per Minute (GPM).

- First, determine the volume in milliliters (V).
- Next, determine the drop factor (DF).
- Next, determine the time in minutes (T).
- Next, gather the formula from above = GPM = (V * DF) / T.
- Finally, calculate the Gtts Per Minute (GPM).
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

Volume in milliliters (V) = 150

Drop factor (DF) = 20

Time in minutes (T) = 5
