Patient Considerations
Active Lifestyle
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.
Light on body. Pens are easy to use and do not remain attached to the body, senor is light on the body.
Avoiding Highs and Lows
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.
Limited customizability. System integrates the Dexcom G6/G7 or Libre CGM for high or low alerts but requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day.
Comfort
More tape is needed for Medtronic sensors.
Many components. Have to carry pens and pen needles. CGM is attached to the body.
Easy Insulin Dosing
Sensor trends can be used for dose adjustment.
NovoPen 6: The maximum dose is 60 units, and doses increase in 1-unit increments. NovoPen Echo Plus: The maximum dose is 30 units, and doses increase in 0.5-unit increments
Easy to Use
Rechargeable sensor transmitter but has the most steps to change sensor.
Simple design. Replaces regular insulin pen. No additional devices to add on.
Fewer Fingersticks
2 daily finger-sticks are needed to calibrate the sensor.
Factory-calibrated sensor. Finger sticks needed for backup only.
Privacy
Somewhat discreet. Ability to see sugar on watch or phone. Sensor requires regular meter use.
Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. View recommendations and data on a smartphone.
