Answers

Answer 1

166.7 ml/hr for 60 min is the setting for infusion pump

To calculate flow rate in mL/hr, use unitary method

total fluid volume (250 mL)/ infusion time (90 mins) , (2.78 mL/min) to determine mL/hr, multiply by number of minutes in an hour (60) = flow rate (166.7 mL/hr).

infusion time fluid volume

90 min = 250 ml

1 min = 2.7 ml

60 min = 166.66
