The Bolus Calculator helps you calculate the right amount of insulin for your meals and corrections for high blood sugar values.
How do I set up the Bolus Calculator?
- To get started, open a new entry screen in the mySugr Logbook by selecting the '+' button.
- Import or manually input your blood sugar value and/or carb value and select the “Calculate” button in the Bolus Calculator field.
- For each imported bolus, there is a new “Insulin (bolus)” entry with the date, time and the number of units delivered. The number of units is shown within a tile as shown below.
- In some locations, the first time you use the mySugr Bolus Calculator we will ask you to unlock the Bolus Calculator by entering the activation code provided by your healthcare professional.
- If you are not asked for an activation code, you will be able to continue and set up your mySugr Bolus Calculator.
- To use the mySugr Bolus Calculator you need to set up a passcode, touch or face ID on your phone to make sure that only you can configure or change your Bolus Calculator settings. Before being able to receive any bolus recommendation, you will be asked a handful of questions about your personalized settings.
Important definitions and default values
- Active insulin: Insulin currently in the body that is working to lower blood sugar. This amount does not include any insulin that is working to account for carb intake. It also does not include basal insulin.
- Target range: Acceptable upper and lower blood sugar level when fasting or before a meal (Default: 80–130 mg/dL or 4.4–7.2 mmol/L).
- Hypoglycemia: The setting below which the blood sugar level is considered hypoglycemic (Default: 70 mg/dL or 3.9 mmol/L). In that situation you will be prompted with a recommendation to eat an appropriate amount of carbs.
- Offset time: Expected amount of time before insulin begins to lower blood sugar levels in the body (Default: 60 minutes).
- Acting time: Total length of time the insulin is expected to be effective at lowering blood sugar (Default: 4 hours and 30 minutes).
- Maximum bolus: The maximum amount of insulin to be delivered at one time. This serves as a safety measure against unintended large boluses by asking your for added confirmation (Default: 25 U).
- Insulin increments: The amount in units (U), usually 0.1 U 0.5 U or 1 U, by which your insulin dose is adjusted (Default: 1 U).
- Meal rise: The maximum increase in your blood sugar level that is to be tolerated after a meal without the need for an additional correction bolus (Default: 75 mg/dL or 4.2 mmol/L).
- IMPORTANT: These settings determine how your insulin dose is calculated, and as you can imagine, it’s important to get them right. Please do not choose your settings without consulting your doctor or healthcare professional.
To ensure that the mySugr Bolus Calculator settings fit your diabetes therapy, you will be asked to review your settings every three months.
Time-dependent settings
- Active insulin: Insulin currently in the body that is working to lower blood sugar. This amount does not include any insulin that is working to account for carb intake. It also does not include basal insulin.
- To define your settings per time period:
- Select “time-dependent” (iOS) or
- enable “time- dependent setting” (Android) during the setup flow.
- Select the time period and enter/edit the adequate value.
- Repeat for each time period affected as each time period ends when the next one begins.
