BolusCalc

Insulin Bolus Calculator

Free · Designed for iPad

his app is designed for simple calculations of insulin doses in the Canadian home and school setting (although calculations can also be done in U.S. mg/dL blood glucose units). There are 4 screens available: The “Simple Insulin Bolus” screen calculates an insulin dose for people on multiple daily injections (MDI) based on carb ratio, correction/sensitivity factor (ISF), target BG (the default is 6 mmol/L or 100 mg/dL for daytime, and 8 mmol/L or 120 mg/dL for bedtime), carbs to be consumed, and current BG. The “Simple Insulin Scale” screen generates a simplified insulin sliding scale for people who are on a fixed dose of carbs at a meal, based on baseline insulin dose, ISF, and target BG. The “Full Sliding Scale” screen generates a full insulin scale for people on MDI based on carb ratio, ISF, and target BG. The “Correcting for Arrows” screen allows CGMS users to calculate an increase or decrease in insulin dose (or carbs) to account for positive or negative direction arrows.
