Well my son has been on the pump about 6 weeks now and wanted to start to get familiar with the combo bolus so I trial. Was hoping those that use this feature can put some perspective on my results.
At 12:30 pm yesteday afternoon his BG was 216. He went to lunch at school and came back to the nurses office at 1:08 where he bolused 16 units to cover the lunch. The nurse always tests him before he gets on the school bus and yesterday at 2:30 pm he was 148.
Right before dinner at 5:30 pm his BG was 192 and I had him bolus 1 unit for correction.
This is when the test started.
He had pizza only - 30 carbs to a slice and he had 5 slices.
I had him combo bolus at 50-50 so 7.5 units of normal bolus and 7.5 units spread over 2 hours.
His premeal BG was 192 ( I know the best case scenerio is to start in in a good range) but . . . diabetes is not perfect.
So Premeal was 192. At the one hour mark he was 179, at the two hour mark he was 168. So if I understand the purpose the 2 hours is to see if the first portion of the bolus was the correct amount needed to maintain nomal BG levels 2 hours after the meal.
I checked again at 4 hour mark and BG was 193. As I read the purpose of the four hour check is to see if the 2nd portion of the bous - the extended bolus was the ocrrect amount needed to maintain nrmal BG levels 4 ohus after the meal.
I tested him at the 5 hour mark and he was 186.
I was supposed to check him at the 6 hour mark and not the 5 hour mark but he had reached the point where he needed to adjust his basal level for sleep so I corrected the 186. He woke up at 119.
So I guess my question is did the 50-50 combo bolus do what it was supposed to do or did I need to ensure he was within normal range before starting the test. It seems to me based on the testing done his numbers were dropping and at the 4 hour mark they were within one point of the premeal bolus.
At the 5 hours point they were lower so a fair assumption would be that had I tested at the 6th hour he would have been in the 160-170 range.
Would love your feedback.
