What is the IV infusion rate in drops per minute? Given: Amount of fluid: 1200 mL Total time of infusion: 12 hrs Administration set drop factor: 15 gtts/mL

Drop Factor = 60 drops per mL = 83 833 ≈ 84 drops/minutes The formula to calculate how many hours will it take for the IV to complete before it runs out is: Time (hours) = Volume (mL) Drip Rate (mL/hour)

An IV infusion set is used to

administer fluids and medications directly into the blood stream. Infusion or flow rates are adjusted to the desired drops per minute by a clamp on the tubing. The flow rate is calculated by the nurse in drops per minute (gtts/min). To calculate this, one must know the administration set drop factor, which is a constant. Macrodrip tubing administers a larger drop and may be used for 10 gtts/mL, 15 gtts/mL or 20 gtts/mL.

Microdrip tubing

administers 60 gtts/mL. These are called drop factors. The drop factor is the number of drops contained in 1 milliliter.

Calculation of IV drip rates: IV Infusion Rates Formula

Example:

The physician has ordered D

5 W 1200 milliliters in 12 hours using 15 drops per milliliter infusion rate. What is the IV infusion rate in drops per minute?

Given:

Amount of fluid: 1200 mL

Total time of infusion: 12 hrs

Administration set drop factor: 15 gtts/mL

IV infusion rate: ?

gtts/min

Step 1: Convert 12 hours into minutes.

12 hrs x 60 min/hr = 720 min

Step 2: Use the formula above to calculate the IV infusion rate.

IV infusion rate =

x 15 x 15 (1) (48) = 25 Therefore, the IV infusion rate is 25 drops per minute. x Drop factor (gtts/mL) = IV infusion rate (gtts/min) Note: drops are always rounded to the nearest whole number.quotesdbs_dbs7.pdfusesText_5
