## Beware the Medtronic Easy Bolus button | ||
## Know your settings | ||
|
||
Medtronic's easy bolus button has been the cause of several accidental boluses when the pump has been carried in a pocket. Best practice would be to disable the Easy Bolus button since you will be doing boluses from the phone anyways. | ||
Do not enter settings that you are unsure of. For example, if you haven't any idea what your carb ratio is, please don't enter a wild guess. Instead, test your settings and talk to your health care provider about what your appropriate settings should be. | ||
|
||
## Health app permissions | ||
## Understand the App Displays | ||
|
||
Do not let other apps, such as Spike App or MyFitnessPal, on your iPhone write carbohydrates to Health app. Loop could read those carbohydrates and you could be dosed for those carbohydrates. Check your [Health](../build/health.md#loop-permissions) permissions. | ||
If you do not understand the components displayed in the graphic below, please spend time reviewing the information at [Displays](../loop-3/displays-v3.md). | ||
|
||
## Finish your Medtronic priming | ||
![main loop screen when running nominally with annotation for heads-up-display, charts and toolbar](../loop-3/img/loop-3-main-annotated.png){width="450"} | ||
{align="center"} | ||
|
||
After a site change and reservoir rewind, Medtronic's pump will have a menu on the pump screen related to finishing your prime. Make sure you complete that screen and always return to the main menu. Medtronic's pump won't resume basal insulin delivery until that priming screen is completed. | ||
## Carb Entry and Insulin Delivery | ||
|
||
## Know your settings | ||
If you configured the app with closed-loop enabled: | ||
|
||
* Once carbohydrates are entered into <span translate="no">Loop</span>, the algorithm will begin to dose insulin to anticipate those carbs | ||
|
||
If you entered carbs and then changed your mind on the amount or the time at which they were eaten, use these [instructions](../operation/features/carbs.md#edit-meals) to delete or edit them. This will make <span translate="no">Loop</span> better able to predict blood glucose and adjust insulin delivery appropriately. | ||
|
||
## How to Cancel a Bolus | ||
|
||
Once a bolus starts, the progress of that bolus appears in the [HUD Status Row](../loop-3/displays-v3.md#hud-status-row). Note that the phone must be held in portrait mode to see this. Simply tap on the row that shows the delivery to halt the bolus. | ||
|
||
![bolus-in-progess message: message size is 500 x 50 pixels](../loop-3/img/status-row-bolus-in-progress.svg){width="350"} | ||
|
||
Do not enter in settings that you are unsure of. For example, if you haven't any idea what your carb ratio is, please don't enter a zero or a wild guess. Instead, test your settings and talk to your health care provider about what your appropriate settings should be. | ||
## Understand Delivery Limits | ||
|
||
## How to Cancel Carbs | ||
With each cycle, <span translate="no">Loop</span> generates a glucose prediction and a recommended dose (positive or negative) to bring you to your correction range. | ||
|
||
Once carbohydrates are entered into Loop, the algorithm will begin to dose insulin to anticipate those carbs. | ||
* The automated response to a positive recommended dose depends on your Dosing Strategy and is adjusted by your Delivery Limits | ||
|
||
If you entered carbs and then changed your mind on the amount or the time at which they were eaten, use these [instructions](../operation/features/carbs.md#edit-meals) to delete or edit them. This will make Loop better able to predict blood glucose and adjust insulin delivery appropriately. | ||
For more information, please read [How do Delivery Limits Affect Automatic Dosing?](algorithm-faqs.md#how-do-delivery-limits-affect-automatic-dosing). | ||
|
||
Make sure [Health](../build/health.md#loop-permissions) permissions are set for Loop to `Write` but **not** `Read` carbs. This avoids a scenario where Loops reads entries from a third-party app. These carbs cannot be edited within Loop. | ||
## Health app permissions | ||
|
||
For older versions of <span translate="no">Loop</span>, or if you customized <span translate="no">Loop 3</span> to read carbohydrates from third-party apps, be aware that you cannot edit those entries inside the <span translate="no">Loop</span> app. | ||
|
||
If you let other apps, such as MyFitnessPal, write carbohydrates to the Health app, <span translate="no">Loop</span> could read those carbohydrates and you could be dosed for those carbohydrates. | ||
|
||
* <span translate="no">Loop 3</span>: review [Customization: Build Time Features](../build/code-customization.md#build-time-features) | ||
* <span translate="no">Loop 2</span>: Check your [Health](../build/health.md#loop-permissions) permissions and review . | ||
