This app is designed for simple calculations of lunchtime insulin doses in the Canadian school setting (although calculations can also be done in U.S. mg/dL blood glucose units). There are five screens available: The Simple Insulin Bolus screen calculates a lunchtime insulin dose for kids on multiple daily injections (MDI) based on carb ratio, correction/sensitivity factor (ISF), and target BG. The Simple Insulin Scale screen generates a simplified insulin sliding scale for kids who are on a fixed dose of carbs at lunch, based on lunchtime carbs, baseline insulin dose, ISF, target BG, and current BG. The Full Sliding Scale screen generates a full insulin scale for kids on MDI based on carb ratio, ISF, and target BG. The Bolusing for Arrows screen allows you to calculate an increase or decrease in insulin dose (or carbs) to account for positive or negative direction arrows for CGMS users. The More School Resources screen contains links to websites devoted to the care of children with diabetes in the school setting. For all screens, there is the ability to share a time-stamped copy of the data generated with a student’s parent or caregiver via text, e-mail or other phone app.
