hi! i'm a student rotating through icu and have a question. if the antibiotic bag reads 120ml/hr to be infused over 30 minutes, what do i set the infusion rate at? is 240ml/hr correct? thanks!
no, the label on the bag gives you both the rate (120 ml/hr) and time (30 minutes) to infuse. you are not given the volume to be infused. if you were told to infuse 120 ml over 30 minutes, then the rate would be 240 ml/hour. where i work, the label on antibiotics gives us all three variables. for example: 50 ml to infuse over 15 minutes at 200 ml/hour.
although with some of the newer infusion devices you only need either the volume or the rate, and the time to infuse and the device will automatically calculate the missing variable. however, should you need to calculate the missing variable this can easily be done.
if you have rate and time to infuse and need to calculate the volume, this can be done using the following formula: (rate x minutes to infuse) / 60.
if you have volume and time to infuse and need to calculate the rate, this can be done using the following formula: (volume / minutes to infuse) x 60.
if you have rate and volume to infuse and need to calculate the time to infuse, this can be done using the following formula: (volume / rate) x 60.
i hope this information is helpful.
