Before Using Auto Mode
Before Using Auto Mode
Device: MiniMed™ 670G insulin pump (MMT-1780K)
It is important that you read and follow the instructions for using Auto Mode in the Getting Started with Auto Mode Guide before you begin.
There are several steps that you need to complete before using Auto Mode for the first time. Some steps take longer than others to process, and some need to be completed before others. To get put your pump into Auto Mode for the first time:
- Use your pump to deliver your insulin for at least 48 hours. This warm up period begins the midnight after the pump starts delivering insulin and it does not require sensor use. Your pump does not require the Auto Mode setting to be turned on for the Auto Mode warm up to occur.
- Turn on the Sensor option and start a sensor if you are not currently using one. For Auto Mode to work, you must have a working glucose sensor.
- Enter your Carb Ratio and Active Insulin Time using one of the following methods:
Individual Bolus Estimate Settings
To enter your Carb Ratio and Active Insulin Time as individual settings:
a) Press Select.
b) Select Options.
c) Select Delivery Settings.
d) Select Bolus Estimate Setup.
e) Select Carb Ratio or Active Insulin Time.
f ) Enter your settings.
Bolus Wizard Settings
To use Bolus Wizard to enter your Carb Ratio, Active Insulin, and other Bolus Wizard settings, review Entering Your Bolus Wizard Settings.
- Check the Home screen for the following:
- An active temp basal
- A current bolus delivery, including a Square Wave® or Dual Wave® bolus
- Delivery suspended
Auto Mode cannot activate, or start working, during any of these conditions. If any of these conditions exist, you must wait until it is completed, or cancel it, before Auto Mode will work.
Warning: Do not put your pump into Auto Mode if you have used the pump in the last 3 days to practice button pressing, or if basal insulin that was programmed into your pump was not your actual basal delivery. Doing so may result in the delivery of too little or too much insulin, which can cause hyperglycemia or hypoglycemia. Auto Mode uses the recent delivery history on your pump to determine the Auto Basal delivery amount you receive.
While you are in Auto Mode, it is important that you enter your carbs and confirm insulin delivery in order for you to receive your food boluses.
To ready your pump for Auto Mode, you must:
- Cancel any active Temp Basal rates.
- Ensure your delivery is not suspended.
- Set your carb ratio.
- Review your high and low limit settings. Your high and low limit settings apply to Auto Mode.
- Enter a BG reading if you have not entered one in the past 12 minutes. If necessary, calibrate your sensor. If you have just started a new sensor, calibrate your sensor, and then wait 30 minutes before you enter a BG for Auto Mode.
The BG readings you enter into your pump may be used to:
- Calibrate your sensor
- Enter Auto Mode
- Remain in Auto Mode when notified by your pump
- Recommend a correction bolus when a BG of 150 mg/dL or higher is entered
If you believe any BG reading result is inaccurate, wash your hands and re-check your BG. When the pump prompts you to enter a new BG, it is important to perform a fingerstick, and enter a new BG.
After the first day of sensor use, the minimum number of calibrations required is one every 12 hours. You may receive an additional Calibrate now alert if the system detects that a calibration is required for accuracy of SG readings. Calibrating 4 times a day is optimal. It is best to calibrate when your glucose is not changing very rapidly. Calibrating when there are or arrows may decrease sensor accuracy. Many find that a good time to calibrate is before meals. Review the Calibration guidelines in the Calibration section of Getting Started with Continuous Glucose Monitoring for more information.
