Patient Considerations
Active Lifestyle
Waterproof when submerged in 2.4 meters of water and must be within 20 (unobstructed) feet of the receiver or mobile device. This device is intended to help people with non-insulin requiring type 2 diabetes better understand their blood sugar numbers.
Body free of devices. Does not remain attached to the body.
Avoiding Highs and Lows
Very limited alerts. This device does not provide alarms and alerts for high, low, and rise/fall rates. This device is intended to track and understand the effects of food on blood sugar for people with type 2 diabetes.
Very short-acting. Absorbs quickly through the lungs to correct high blood sugar but requires attention to prevent lows.
Comfort
Low profile and low maintenance sensor application.
Many components. Have to carry multiple cartridges that can be bulky.
Easy Insulin Dosing
No options. Stelo is intended for use by people with type 2 diabetes who do not require insulin to manage their blood sugar levels.
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
Real-time data and alerts make dose adjustment easier.
Simple design. Whistle-like device for inhaling insulin.
Fewer Fingersticks
Factory-calibrated sensor. Finger sticks needed for backup only.
Frequent finger-sticks are required.
Privacy
Small sensor. Discreet and thin sensor that is easy to hide under clothing.
Hideable. Small, discreet, and portable device that's not as noticeable as injections.
