need hlep with D.A. on flow rates




Jan 16, '05No it should be 800ml to infuse overa time of 480 minutes.
The drops per minute on a pump depends on the what the amount of fluid and for how long. 

Jan 16, '05the problem states this
calculate the following flow rates
a volume of 800 ml is to infuse in 8 hours with an electronic fusion pump.
how do you set the problem up? 
Jan 16, '05Total Volume X gtt factor
time of infusion
This is the forumla that you can use. The only problem is that I do not see a gtt factor in your problem. 
Jan 16, '05Quote from tnstudentnurseThat's the only way you can do it if no gtt factor is stated in the problem.they had us to divide
800 ml. / 8 hr. to get 100 ml/hr for the flow rate 

Jan 16, '05Not arguing with any of you but we learned like this:
800 ml divided by 8 = 100
and pumps deliver 60 drops per min.
so it would be drops over time x ml 60gtt/480min. x 100 ml = 800ml
60 goes into 60 one time, and 60 goes into 480 eight times and multiply 100 by 8 to
get 800ml
I think this is what you were looking for??? 
Jan 18, '05flow rate = ml/hr
800ml/8hr = 100ml/hr = flow rate for electronic pump
If you are hanging by gravity and you need to convert to gtt/min, then you'll need the gtt factor of your tubing. Just say that it is 60 gtt/ml, then you'd do this if you are using diminsional analysis:
gtt/min= 60gtt/1ml x 100ml/1hr x 1hr/60min =6000/60 = 100gtt/min so your drip rate should be 100 drops per minute.
