Description

IV Calc objectives! -calculate ml per hour! -identify two types of administration tubing! -identify iv tubing packages the drop factor in drops per ml (gtt/ml) ! -calculate iv flow rate in drops per min using formula and dimensional analysis! -calculate flow rate for meds over a specific time! -Calc infusion and completion times! -Calc administration of iv push meds! -Calc fluid amounts in ml not liters! ! Important notes: -add zero before decimal point (leading zero)! -no trailing zeros! -ml is always rounded to whole number (ml/hr)! -less than ml is two decimal points ( two decimal points on 1 ml syringe)! -can’t count less than 1 drop, round to whole number! ! ! Iv flow rate calculation • rate expressed in ml per hour! • Without electronic pump, rate is drops per min (gtt/min)! Round to nearest whole number

! ! ! Safety!! - Usual rate ranges from 50-200 ml/hr ! If rate exceeds amount, double check the order and your calculations! ! Calculating IV flow rates in Drops (gtt) Per Min • if pumps not available, rate is manually regulated ! • Determined by drop factor of drip chamber below IV bag! • Adjust gtt/min by counting with a watch with second hand! • Drop factor is printed on package! ! IV tubing • Macrodrop - standard for general infusions , 10, 15, 20 gtt/ml, delivers large volumes! • Microdrop- 60 gtt/ml! ! ! Remember - identifying the drop factor on the Iv package is the FIRST step for admin of IV fluids Gtt/min = round to nearest whole number Formula Method

Calculating Drops per min with large volumes of fluid • preliminary step

Administering multiple fluids • Add ml of fluids together to get total ml of fluids and then proceed as normal...
