Calculate the drip rate for this patient after her bolus is given. Her body weight is 80 pounds. The drop size for your administration set is 10 drops/mL. The body weight given in this question is irrelevant. You already know what rate you need because the doctor gave it to you 180 mL/hr .
Next we will determine the drip rate. The formula is as follows Drip rate in gtt/minute = Total Milliliters Total Minutes Drip factor in gtt/ml. So in our example you would do this 20 mL 1 hr 1 hr 60 min 60 gtt 1 mL. This equates to 20gtt/min or 20 drops per minute. One interesting note When using a micro drip
Substituting in the formula gives 1 000 mL Drip Rate==125 mL/h. 8 hTherefore the patient will receive 125 mL of fluids per 1 hour.

A drip is a small individual drop of a liquid. Drip rate is how fast the liquid drips per unit time. Knowledge on drip rate is mostly used in hospitals to determine the intravenous IV tubing to be used. Formula to calculate drip rate. To calculate drip rate we divided the volume in milliliters by time in hours.
IV Fluid Therapy Calculations Once the overall fluid rate per hour has been calculated taking into consideration maintenance deficit and on going loss this information can be entered into an infusion pump if this is available. If not a drip rate needs to be calculated in mL/minute e.g. A dog needs 116mL/hour 116mL/hour/60 = 1
Calculating Drip Rate In order to control the RATE that the fluid is given to the patient you must actually control the number of drops that drip into the drip chamber of the IV set. If you want to administer one mL of fluid you should give the patient 10 gtts of fluid with a macrodrip or 60 gtts with a microdrip set.
