Patient Considerations
Active Lifestyle
Waterproof. The pump and CGM are waterproof and can be worn for most exercises.
Body free of devices. Does not remain attached to the body.
Avoiding Highs and Lows
Auto basal and bolus insulin. Responds to CGM data by increasing or decreasing basal insulin delivery to prevent highs and lows and maintain a set blood glucose target.
Very short-acting. Absorbs quickly through the lungs to correct high blood sugar but requires attention to prevent lows.
Comfort
Shorter tubing option. A shorter 5-inch tubing option for comfort on body.
Many components. Have to carry multiple cartridges that can be bulky.
Easy Insulin Dosing
Automatically adjusts dosing. Sensor integration allows the pump to automatically adjust insulin doses. More customizable dosing than pens or syringes. Manual bolus button is available for quick dosing without a phone.
Less precise but easy dosing. Dosing may be less precise due to the inhaled method of dosing, but color-coded cartridges make dosing easier. Dosing can also be done based on small, medium, or large meals and can be administered 1-2 hours post meals.
Easy to Use
Easy Dosing. Full control from a smartphone, with the option to manually bolus if needed.
Simple design. Whistle-like device for inhaling insulin.
Fewer Fingersticks
Factory-calibrated sensor. Fingersticks needed for backup only.
Frequent finger-sticks are required.
Privacy
Discreet. Ability to check blood sugar on phone or watch. Ability to bolus on a compatible smartphone. Pump has tubing but can be clipped to clothing or attached to local area with an armband or adhesive sleeve to be discreet when needed. Dexcom's built-in hypoglycemia safety alarm alerts users when glucose is below 55 mg/dl and is always on.
Hideable. Small, discreet, and portable device that's not as noticeable as injections.
