Follow these steps to mimic a square wave bolus with a MiniMed 506 pump:
- Calculate the amount of the desired bolus and decide over what length
of time you want it delivered. Add to this the amount of basal insulin which
would normally be delivered during this time period. This is the total
bolus amount.
- Divide the total bolus amount by the length of time for delivery,
resulting in the amount of insulin per hour.
- Program a temporary basal rate of the amount figured in step 2 for a
duration equal to the desired length of time. Note: You may need to
reset the factory settings for maximum basal rates on your pump before
beginning this procedure. Refer to your pump users manual for
instructions.
For example: (Again, this is just an example, your rates and times may
vary from this.)
Insulin required to cover food intake: 5 units
Desired length of square wave: 2 hours
Normal basal rate: 0.4 units/hour
Total basal insulin for the time period: 0.8 units
Total bolus amount: 5.8 units
Insulin per hour for square wave: 2.9 units/hour
Following this example, you would program a temporary basal rate of 2.9
units per hour for a duration of two hours to mimic the square wave.
