The T:slim has a bolus limit of 25 units, after that is delivered you can have the option of 25 more for a total of 50 units but that's it.
Here is an example of how the problem effects me. I am using an insulin to carb ratio of 1:1.5. For breakfast if I eat a bagel (50 carbs) along with an average size apple (38 carbs) and 8oz of Milk (13 carbs) that comes to a total of 101 carbs so with my ratio I would need 67 units of insulin. The T:slim pump will not allow this much for a bolus. I thought about delaying a bolus but to deliver the initial 50 units would take close to 10 minutes and a delayed bolus has to wait a minimum of 15 minutes before it will begin. This means that the total bolus would take up to 25-30 minutes. This seems to be unacceptable not to mention it would be a big pain in the a$$ to have to do this every time I need to bolus more that 50 units.
I talked to Tandem and they told me that the FDA has set this limit and they cannot change the programming of a pump to accommodate my issue.
I have only had the pump for a few days now and did not see this coming.
I have been out of commission with a major foot problem that had me in a cast for 14 months and now I am looking at surgery in spring. In the mean time I have a lot of pain. I know more exerciser would help my insulin usage but it will be another year before I might be back on my feet (pun intended). Of course loosing weight will help too but find it hard being off my feet.
I Just needed to share my frustration but I'm sure things will work out soon. Low card diet, here I come!
