# Re: [IP] Re: suspending when low-calculations to show what to do

```Hey,
A simple calulation can be done to show that it not necessary to stop the dump during a low for certain.What conditions should you stop the pump.
If my pump rate is 0.5 unit/hr, if I am at 40 bs. I take food as fast as I can and the bs goes up to say 60 bs in 10 min. and still going to say 160 bs in 30 min. If my calibration rate is 1 unit of insulin/40 bs units. In 30 min. AT 0.5 unit/hr I will have delivered 0.25 units of insulin or 0.25 x 40 bs/unit insulin or bs would have fallen 10 bs units. In 10 min. 10/60 x 0.5 units of insulin would have been delivered or bs change would be 40 bs/insulin x 10/60 x 0.5 = 0.333 bs unit.

To repeat this calculation for your purposes you need: (1) rate delivery for the pump, (2)recovery time from low and (3)calibration curves in units of bs units/ units of insulin.
My conclusion for me using my numbers(recovery from low 10 mins or 30 mins,40 bs/units of insulin and 0.5 insulin units/hr pump rate) it is better to eat or drink fast acting carbo immediately. It would be better to go over this calculation with you medical team before  drawing conclusions.
