Insulin sensitivity
Insulin sensitivity is used to decide a correction bolus for a high BG. This is how much your blood glucose will be
dropped with 1 unit of insulin.
1 unit of insulin will lower BG __________ mmol/L (mg/dL).
Active Insulin
Active insulin is the bolus insulin that has already been delivered to your body, but has not yet been used. The pump
considers your active insulin time setting in determining any active insulin still in your body from prior boluses. This
may help prevent hypoglycemia caused by over-correcting for high blood glucose.
Blood glucose and A1C testing
When you check your blood glucose with a meter, you measure blood glucose at the moment you perform the test.
This number gives you key feedback for making present and day-to-day adjustments in your diabetes management.
The A1C test, done at your doctor's, shows you your average blood glucose over the last 60 to 90 days. Both blood
glucose and A1C testing are necessary for good diabetes management.
BG testing
With any insulin therapy, you must monitor your blood glucose 4 to 6 times a day. With insulin pump therapy, blood
glucose testing gives you correct feedback. It also allows you to make prompt changes based on the results. It alerts
you to high blood glucose readings that need changing. It allows you to adjust your insulin to carbohydrate ratio for
certain foods. Your pump only uses fast-acting insulin; as a result, you have no long-acting insulin as a back-up.
Therefore, if your insulin delivery is disrupted on pump therapy, your blood glucose can go dangerously high fairly
fast. This can happen much faster than it could when you were using daily injections with long-acting insulin. Blood
glucose testing is needed to alert you to high blood glucose so you can prevent diabetic ketoacidosis (DKA).
A1C
A1C testing also plays a key part in diabetes management. Sustained high BG levels can cause serious long-term
problems. These problems may be prevented and/or delayed if you maintain your blood glucose levels close to
normal. The best measure of your overall blood glucose is the A1C test. It has been proven that an A1C level of 7.0
or less greatly reduces the risk of problems from diabetes. But, any reduction in A1C is a plus. ADA Clinical Practice
Recommendations state that your A1C should be tested at least every 3 months by your healthcare professional.
