Patient Considerations
Comfort
Somewhat comfortable. Medtronic sensors need more tape than other sensors. Largest pump option.
Active Lifestyle
Exercise mode. Manually increase blood sugar target range to 150 mg/dl during activity. System responds to blood sugar changes during activity automatically. Pump is not waterproof.
Avoiding Highs and Lows
Limited auto-basal. Auto-basal only responds to hyperglycemia to maintain a target blood glucose level between 100 mg/dl and 120 mg/dl. Auto-basal is available every 5-minutes to correct blood sugar above 120 mg/dl (12 corrections per hour). Automatic insulin delivery settings are not adjustable. Auto-bolus is not available.
Easy to Use
Easy software. Software makes many dosing decisions. Can be difficult to keep automatic insulin dosing features working. Requires fewer parts than do-it-yourself systems.
Easy Insulin Dosing
Automatically adjusts settings. Automatically adjusts insulin to reach one of two preset targets. Will automatically revert to manual mode in certain situations. Basal and bolus in 0.025 increments. Extended bolus unavailable when using automated insulin delivery mode.
Fewer Fingersticks
2 daily fingersticks are needed to calibrate the sensor.
Privacy
Somewhat discrete. Ability to check blood sugar on phone or watch. Pump has tubing but can be clipped to clothing or placed in a pocket to be discreet when needed.
