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.
Body free of devices. Does not remain attached to the body.
Avoiding Highs and Lows
Custom alerts can be set for highs, lows, and rapidly rising or falling glucose levels. Trend arrows show the direction glucose is heading, with the rate of change.
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
Real-time data and alerts make dose adjustment easier.
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
No scanning required. Readings are sent directly to the mobile app every 5 minutes.
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
Quiet Mode (Vibrate). All system alerts will vibrate when this setting is enabled. Urgent Low Soon and technical alerts will sound if not acknowledged.
Hideable. Small, discreet, and portable device that's not as noticeable as injections.
