How To Calculate Drop Factor

In that case youd need to calculate the time first and then calculate the dpm.

How to calculate drop factor. With the infusion rate. So the formula usually goes as. To calculate the drops per minute the drop factor is needed. Gtt factor x volume in ml gttminute.

Drop factor in gttsml. Mlhr divided by 60 minhr x drop factor. Multiply the drop factor by the previous product. Tv total volume.

Over divided by. Instead of giving the total time the question may have the infusion rate. Just remember tv will make you deaf over time which if interpreted is. For example burette contains a plastic dropper which gives the number of drops per ml the drop factor.

The drop rate is 42 drops per minute. Iv fluid of 1000ml to infuse for 8 hours using tubing with drop factor of 15. Use this formula to calculate gravity flow rates. Lets try an example.

Iv drip rate volume to be given in ml drop factor in gttsmintime in minutes in case the time is specified in hours then the flow rate will be. 125mlhr divided by 60 minhr 208mlmin. Deaf df or dip factor. The drop factor is 20 drops per ml.

Total volume x drip factor time flow rate gttmin smart recall. We know infusion rate mlhr. The common drop factors are 10 dropsml blood set 15 drops ml regular set and 60 drops ml microdrop. Read the prescription and find the drop factor.

To solve this we first need to find out how many millilitres are transfused per minute we do this as follows. In our example if the drop factor is 20 then you would multiply 20 by 2 and the answer is 40. 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 gttsml which equals the iv flow rate in gttsmin. 6 hours drop factor 60 so drops per minute dpm 2500 6 60 60 2500 6 41666.

The algorithm of this iv drip rate calculator applies the flow rate formulas explained below if the time is expressed in minutes then the drip rate will be. Min hr x by 60 6 hr x 60 360 min. 1000ml for 8 hours 125mlhr. If we divide 42 drops per minute by 20 drops per millilitre well find out how many millilitres per minute.

Weve established an easy way for you to recall the formula listed above.
