Patient Considerations
Active Lifestyle
Water-resistant for up to 3 feet deep for 30 minutes and light on the body, does not get in the way of activity.
Water-resistant when submerged in 2.4 meters of water and must be within 20 (unobstructed) feet of the receiver or mobile device.
Avoiding Highs and Lows
Optional glucose alerts for low and high glucose levels. Trend arrows show the direction glucose is heading, with the rate of change.
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.
Comfort
Lowest profile sensor and smallest adhesive (about the size of two stacked U.S pennies).
Low profile and low maintenance sensor application.
Easy Insulin Dosing
Sensor trends can be used for dose adjustment.
Real-time data and alerts make dose adjustment easier.
