How to Use ManageBGL.com

You should use ManageBGL.com just 'like a pump', entering in BGLs as you take them, and Carbs and Insulin as you have them. If you take a BGL before you eat, use the Wizard to calculate the dose, and adjust it if necessary.

These screens are the quickest way to enter data, as they do not require you to enter the time - it is assumed you are entering the data 'as it happens'. Also, the Wizard takes into account your active insulin (Insulin On Board or IOB) as it happens, as well as your BGL target in 3* hours time (*-depending on your active insulin time).

If you have to enter data after the events actually happen, use the logs screen.

Entering Carbs

Q. It takes me 20 minutes to eat 20g carbs. Should I enter more than one 20g log entry?
A. No, carbs take one to two hours to be absorbed anyway, so you only need a single carbs entry of 20g.

Wizard and Chart/Prediction Setup

Before you can use the Wizard or prediction functions, you need to setup your ratios. You can do this with the help of a Health Care Professional, or see various guides.

Simulation of Dawn Phenomenon (DP)

The Dawn Phenomenon refers to the rise in BGL that occurs in some PWD before or as they wake up.

Assuming you are using a pump, your basal rate should normally be set to zero. To simulate the Dawn Phenomenon, set your basal rate like this:

This means that for each hour from 6am-8am, you will experience a rise in BGL equivalent to 0.345 units insulin:

So,
0.345 units insulin would be required per hour to offset DP
Now, assuming an insulin to carb ratio of 1 unit : 30 grams
= 0.345 units x 30 grams carbs
= equivalent to 10.35 grams eaten per hour.
= 0.345 x 100mg/dL
= equivalent to 34.5 mg/dL rise in BGL per hour.

You can fine tune when this DP rise starts and finishes by changing the times above.

If you are NOT on a pump, then you would reduce your normal basal rate in the hours 6:00-8:00 by 0.345.
