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 drug infusion rate?
This can be done in stages: To calculate the millilitres/hour we first need to work out what dose is contained in one millilitre of the infusion dosage. We can do this by dividing the volume of the dosage by the weight of the medicine it contains. In this case 500ml/500mg = 1ml/mg.
How do you calculate drop factor and infusion time?
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) .
How do I calculate flow rate?
Q=Vt Q = V t , where V is the volume and t is the elapsed time. The SI unit for flow rate is m3/s, but a number of other units for Q are in common use. For example, the heart of a resting adult pumps blood at a rate of 5.00 liters per minute (L/min).
How many drops are in 1 mL of IV fluid?
Drop factor = the number of drops it takes to make up one ml of fluid. Two common sizes are: 20 drops per ml (typically for clear fluids) 15 drops per ml (typically for thicker substances, such as blood)
Do you round up or down for drops per minute?
Intravenous infusion rates for crystalloid and colloid solutions, blood and blood products are expressed as guttae per minute or drops per minute, or millilitre per hour (mL/hr). These are always rounded to the nearest whole number for adults and rounded to the nearest 1 decimal place (tenths) for children.
How do you calculate flow rate in nursing?
To perform this calculation, you need to know the total volume to be infused in milliliters and the amount of time for the infusion. Use this formula: For example, if your patient needs 1,000 ml of fluid over 8 hours, find the flow rate by dividing the volume by the number of hours: The flow rate is 125 ml/hour.
What is GTT per minute?
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).
How many GTTS are in a mL?
The type of tubing is usually 10, 15, or 20 gtt to equal 1 mL in standard microdrip sets, and 60 gtt to equal 1 mL in mini or microdrip sets.
How do you calculate drip mcg/kg min?
What dose of nitroglycerin (mcg/min) is the patient receiving? To find mcg/kg/min: Use the formula for mcg/min and divide by patient's weight (kg).
How many drops are in a drip set?
Most macro sets are either 10, 15 or 20 drops to make 1 mL. The other drip set is a micro set, and it either takes 45 or 60 drops to make 1 mL. When giving most medications via continuous infusion, micro drip sets are the preferred method.
How do you find the 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.
