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. The reader must be within 1.5 inches of the sensor to scan it.
Limited Adjustability. No way to adjust long-acting insulin for higher activity on the fly, but the device is water-resistant.
Avoiding Highs and Lows
Alerts are not available. High or low glucose alarms are not available. Trend arrows show the direction glucose is heading, with the rate of change.
Limited customizability. System requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day.
Comfort
Lowest profile sensor and smallest adhesive.
Free of tubing. Patches do not have tubing, but it must be worn in areas that are easy to reach for insulin dosing.
Easy Insulin Dosing
Scanned sensor readings can be used for dose adjustment.
Simple with few steps. 24-hour bolus range: up to 36 units per 24 hours, doses in 2-unit increments. Preset basal rate of 20, 30, or 40 units per 24 hours.
Easy to Use
Requires scanning. Self-application and manual scanning every 8-hours are required. Easy self-application.
Simple with few steps. Patch is replaced every 24-hours with insulin administered at the click of a button.
Fewer Fingersticks
Factory-calibrated sensor. Finger-sticks needed for backup only.
Frequent finger-sticks are required.
Privacy
Somewhat discreet. Scanning feature makes it easy to monitor blood glucose levels discreetly.
Hideable. Bulkier patch pump, but not as noticeable as injections. Bolus button can be used discreetly through clothing.
