How Do You Calculate an Iv Drop Rate

To calculate the drops per minute, the drop factor is needed. The formula for calculating the IV flow rate (drip rate) is total volume (in mL) divided by time (in min), multiplied by the drop factor (in gtts/mL), which equals the IV flow rate in gtts/min.

How do you calculate drop factor?

Drop factor is the number of drops it takes to equal 1 ml with a specific type of IV tubing. The drop factor is stated on the tubing package. Example: IV order D51/2 NS at 120 ml/hr The drop factor is a 15 gtts/ml and the flow rate is 120 ml/hr. Order is written as mg/hr.

How do you calculate drop factor GTT?

1. Order: 1000 mLof D5/W to infuse 130 mL /hr.
2. Drop factor of tubing is 20 gtts = 1 mL.
3. Formula:
4. mL/hr X drop factor = gtt/min.
5. 60 minutes.
6. 130mL/hr x 20 gtt/min = 2600 = 43 gtt/min.
