I am trying to refresh my math skills that I haven't used in a long time. The problem is a procainamide drip is ordered for 2mg/min. the standard mixture is 2g in 500 ml. What should the iv pump be set for ml/hr? I need a formula or something. Thanks
2g/500mL=2000mg/500mL=20mg/5mL=2mg/0.5mL (1g=1000mg by definition)
Since there are 2mg in each 0.5mL, the flow rate should be 0.5mL/min.
and 60 minutes x 0.5mL/minute = 30 mL/hour.
As a check, 30 mL/hr x 2mg/0.5mL=120 mg/hr. Also 2 mg/min x 60 min = 120 mg/hr.
Need Help with this drug calculation
