Dog weighs 44 poundsDosage is 12 mg/kg

Concentration is 2.5%

• First, convert all units to the same unit of measure:– 44lb 2.2lb per kg= 20 kg

– Concentration is 2.5% = 2.5g/100ml = 25mg/ml

• Next, multiply weight times dosage– 20 kg x 12mg = 240mg needed

• Finally, divide this by the concentration of the drug

– 240 mg 25 mg/ml = 9.6 ml

• Multiply Wt x dosage– 10 kg x 10 ml/kg/hr = 100 ml/hr= How many mls in 1

hour

• Multiply by drops per ml delivered by dripset– 100 ml/hr x 15 drops/ml = 1500 drops/hr

• Since you don’t want to count for a whole hour, divide by 60 to get drops per minute– 1500 d/hr 60 min/hr = 25 d/min

Dripset 10 d/ml

• Calculate total volume needed (ml). (This is weight times dosage stuff again)– 600 lb x 30 ml/lb= 18,000 ml/day

• Multiply by drops/ml the dripset delivers to get drops per day– 18,000ml/day x 10 d/ml = 180,000 drops/day

• Divide by 24 hours in a day to get drops per hour– 180,000d/day 24hrs/day = 7500 drops per hour

• Divide by 60 minutes per hour to get drops per minute– 7500drops/hr 60min/hr =125 drops per minute

200 g rat27.5 ml/lb/day

Dripset 60 drops/ml

• Convert to the same unit of measure– 200 g = 0.2 kg

– 27.5 ml/lb/day x 2.2 lb/kg = 60 ml/kg/day

• Multiply weight times dosage– 0.2 kg x 60 ml/kg/day = 12 ml/day

• Divide by 24 to get mls per hour– 12 24 = 0.5 ml/hr

• Then…

Go to next slide

• Now, when you are dealing with a 60 drop/ml dripset, life becomes easier.

• So far we’ve figured out that we need 0.5 ml/hr for Ratsy. The next two steps cancel each other out with a 60 d/ml set!

• Normally you would have to multiply by the number of drops/ml the dripset delivers, and divide by 60 minutes in an hour, right?, BUT…

• 0.5ml/hr x 60 drops/ml 60 minutes/hr= 0.5 drops/min

EASY AS…
