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.
Waterproof transmitter when submerged in up to 2.5 meters of water for 30 minutes and must be within 20 feet of a connected mobile device.
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.
Measures sensor glucose 24/7 and sends alerts when a high or low is detected. Trend arrows show the direction glucose is heading, with the rate of change.
Comfort
Low profile and low maintenance sensor application.
More tape is needed for Medtronic sensors.
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.
Sensor trends can be used for dose adjustment.
Easy to Use
Real-time data and alerts make dose adjustment easier.
Rechargeable sensor transmitter but has the most steps to change sensor.
Fewer Fingersticks
Factory-calibrated sensor. Finger sticks needed for backup only.
2 daily finger-sticks are needed to calibrate the sensor.
Privacy
Small sensor. Discreet and thin sensor that is easy to hide under clothing.
Somewhat discreet. Ability to see sugar on watch or phone. Sensor requires regular meter use.
