33IV FlowRatesExpressed: cc/hr andgtt/min1. Find the cc/hr flowrate2. Find the gtts/min flowrate
4MEMORIZE FORMULAVOLUME ÷ TIME = CC/HR.(in cc) (in hrs)
5IV Flow RatesExamples cc/hr.#1 Order: LR 1000cc over 8 hrs(Vol) 1000 ÷ 8 (time) =125 cc/hr.Use whole # for drip rates#2 Order: NS 500cc over 12 hrs500 ÷ 12 = 41.6= 42 cc/hrUse whole # for flow rates
• Example: gtts./min.• Memorize formula:• cc/hr. x gtt factor60 min.#1.• 125cc/hr , set calibration or drop factor is 15gtt/cc• 125 x 15 = 31.25 or60 31 gtts./min.6IV FLOW RATES
Example 2, Piggy back medications• 1 g of Methicillin in 50cc to run over30 minutes• Using a micro dripper, how manydrops per minute should IV run?11
1233Infusion TimeTotal time for given volume of IVFto infuseInfusion Time = Total Vol.cc/hr.Example 1 = 1L NSS @ 100cc/hr.1000 = 10 hrs.100Example 2 1L D5W @ 125/hr.1000 = 8 hrs.125

2459Critical Care Drugs1. Ordered by dosagesi.e., mcg/kg/minmg/minYou will need to find cc/hr.2. Should use IV pump! If not,use mini-dripper only!REMEMBER A MINIDRIPPER = 60 gtts / cc3. Be sure you have like units.4. Very potent drugs!!
25CRITICAL CARECALCULATIONSOrder: Lidocaine 4mg/minOn Hand: Lidocaine 1g/250ccWhat is IV flow rate?? cc/hr?1. Convert to like units: 1g=1000mg2. 1000 mg: 250 :: 4mg: x cc1000x = 1000x = 1cc/min.
26601 cc / minute, the questionasked for cc/hr.!!WE NEED HOURLY RATESO STEP 3.3. Multiply by 60 min. to getcc/hr1 cc/min (60 min) = 60 cc/hris our answer.
2761OrderPronestyl 3mg/minHave on Hand500mg Pronestyl in250 cc D5WRate in cc/hr??1. No conversion necessary2. 500 mg : 250 cc = 3 mg : Xcc500 x = 750X = 1.5 cc/min.1.5 cc/ minute , we need cc/hr.
28Pronestyl3. calculate the flow rate in cc/hr1.5 cc/min x 60 min ( per hr)= 90 cc/hr.
