# Your AAPS profile
Your **AAPS Profile** is a set of five key parameters which define how **AAPS** should deliver insulin in response to your sensor glucose levels. These are the main parameters **AAPS** is built upon. As you progress through the **Objectives**, you will unlock additional modifiable parameters (like SMB settings), but the performance of these features rely on your underlying **Profile** being correct. The **Profile** incorporates:
* [duration of insulin action](#duration-of-insulin-action-dia) (DIA),
* [glucose targets](#glucose-targets),
* [basal rates](#basal-rates) (BR),
* [insulin sensitivity factors](#insulin-sensitivity-factor-isf) (ISF) and
* [insulin-to-carb ratios](#insulin-to-carb-ratio-icr) (IC or ICR).
As part of **AAPS**’ management, users should continually assess and scrutinise the accuracy of their **Profile** settings. It is recommended to take the settings in the order they are presented here. Старайтесь выверить одну настройку прежде чем переходить к другой. Двигайтесь небольшими шагами, не вносите большие изменения сразу. Don't forget to activate the new profile after each change. Regularly [backup your **Profile**](#YourAapsProfile_Profile-backup) settings by exporting your Preferences.
Your **Profile** settings interact with one another - you can have 'wrong' settings that work well together in certain circumstances but do not in others. For instance, if a too-high basal happens to be at the same time as a too-high **CR**. This means that you need to consider the settings individually and check they work harmoniously together in a variety of circumstances.

```{admonition} Your diabetes may vary
:class: information
**Profiles** vary significantly from person-to-person.
For basal rates (BR), insulin sensitivity factors (ISF) and insulin-to-carb ratios (IC or ICR), the absolute values and trends in insulin requirements vary significantly from person to person, depending on your biology, gender, age, fitness level etc. as well as shorter term factors like illness and recent exercise. For more guidance on this, the book [“Brights Spots and Landmines”](https://diatribe.org/bright-spots-and-landmines/) by Adam Brown is an excellent book to read.
```
The four last parameters (glucose targets, basal rates, insulin sensitivity factors and insulin-to-carb ratios) can be set to different values, changing hourly if required, over a 24-hour period.
Screenshots from **AAPS** of an _example_ profile are shown below. Please note, this sample profile below shows a large number of timepoints. When you start out with **AAPS**, your profile is likely to be much simpler.
(your-aaps-profile-duration-of-insulin-action)=
## Duration of insulin action (DIA)
### Description
The length of time that insulin takes to decay to zero.
The duration of insulin action is set to a single value in **AAPS**, because your pump will continually infuse the same type of insulin.
In combination with the [insulin type](#Config-Builder-insulin), this will result in the [insulin profile](#AapsScreens-insulin-profile), as shown in the image above. The important thing to note is that the decay has a **long tail**. If you have been used to manual pumping, you have probably been used to assuming that insulin decays over a much shorter period i.e. about 3.5 hours. However, when you are looping, the long tail matters as the calculations are far more precise and these small amounts add up when they are subjected to the recursive calculations in the **AAPS** algorithm. Therefore, **AAPS** uses minimum 5h as **DIA**.

### Impact
Too short **DIA** can lead to low BGs. And vice versa.
If **DIA** is too short, **AAPS** will calculate too early that your previous bolus is all consumed, and if your **BG** is still high, it will over-deliver in insulin. (Фактически, алгоритм не выжидает, а продолжает добавлять инсулин, предсказывая, что произойдет). This essentially creates ‘insulin stacking’ that **AAPS** is unaware of. This is especially noticeable at night, if you see negative IOB with no other explanation than the queue of the last bolus.
Example of a too-short **DIA** is a **high BG** followed by **AAPS** over-correcting and giving a **low BG**.
### How to set it
The **figure below** shows an example of how the **DIA** set in an **AAPS** profile.
The **DIA** setting is often set too short by new users. A **DIA** of 6 or 7 is probably a good place to start. A growing number of people find that a **DIA** of 8 to 9 hours works good for them. See the additional reading mentioned above.
(profile-glucose-targets)=
## Glucose targets
### Description
Your **BG target** is a core value and all of **AAPS** calculations are based on it. It is different from the target range which you usually aim to keep your blood glucose values in. The target is used in **AAPS** calculations: if **AAPS** predicts that your **BG** will land outside the target range, then it will take action to take you back in said range.
The targets can be defined within those boundaries :
| | _Low_ target | _High_ target |
| ------- | ---------------------- | ---------------------- |
| Minimum | 4 mmol/l or 72 mg/dL | 5 mmol/l or 90 mg/dL |
| Maximum | 10 mmol/l or 180 mg/dL | 15 mmol/l or 225 mg/dL |
### Impact
If the target in your **Profile** is very wide (say, 3 or more mmol/l [50 mg/dl or more] wide), you will often find little **AAPS** action. This is because **BG** level is predicted to be somewhere in that wide range, and thus temporary basal rate are unlikely to be actioned by **AAPS**.
### How to set it
The **figure below** shows an example of how the target can be set in an **AAPS** profile.
**BG** targets are set according to your personal preferences and requirements. For example, if you are concerned about hypos at night, you may set your target slightly higher at 117 mg/dL (6.5 mmol/L) from 9 pm - 7am. Если вы хотите убедиться, что у вас достаточно активного инсулина (IOB) утром перед болюсом на завтрак, можно установить нижнюю цель в 4. ммоль/л с 7 до 8 утра.
When In [Open Loop](#Preferences-pen-loop), especially when progressing through [the first objectives](../SettingUpAaps/CompletingTheObjectives.md), using a wide range target can be a good option while you are learning how **AAPS** behaves and adjusting your **Profile**.
When In [Closed Loop](#preferences-closed-loop) (starting at **[Objective 6](#objectives-objective6)**), it is recommended to reduce the range until you have a single target for each time of the day (_Low_ target = _High_ target), to make sure that **AAPS** reacts promptly to **BG** fluctuations.
(your-aaps-profile-basal-rates)=
## Basal rates
### Description
Базальная скорость инсулина (ед./час) обеспечивает фоновый инсулин, поддерживая нужную гликемию в отсутствие пищи или физических упражнений.
Инсулиновая помпа подает небольшое количество быстродействующего инсулина каждые несколько минут, не позволяя печени выделять слишком много глюкозы, и давая возможность глюкозе перемещаться в клетки организма. Базальный инсулин обычно составляет от 40 до 50% суточной дозы (TDD), в зависимости от диеты, и обычно следует суточному ритму, с одним пиком и одной долиной потребности в инсулине в течение 24 часов. For more information, chapter 23 of [“Think like a Pancreas”](https://amzn.eu/d/iVU0RGe) by Gary Scheiner is very useful.
Most type 1 diabetes educators (and people with type 1 diabetes!) agree that you should work on getting your basal rates correct, before attempting to optimise your ISF and ICR.
### Impact
Точно определенная базальная скорость позволяют просыпаться в заданном диапазоне, пропускать еду - или есть - раньше или позже, без падений или взлетов ГК.
Повышенная скорость подачи базала может привести к низкому уровню ГК. And vice versa.
**AAPS** ‘baselines’ against the default basal rate. Если базал слишком высокий, то «нулевая временная скорость» будет определяться при большем отрицательном значении активного инсулина IOB, чем нужно. This will lead to **AAPS** giving more subsequent corrections than it should to bring IOB ultimately to zero.
So, a basal rate too high will create low **BGs** both with the default rate, but also some hours hence as **AAPS** corrects to target.
Conversely, a basal rate too low can lead to high BGs, and a failure to bring levels down to target.
### How to set it
The **figure below** shows an example of how the basal rates can be set in an **AAPS** profile.
Setting your basal rates right is done by trial and error, and should be done in consultation with your diabetic team.
There are basal testing methods which usually entails observing your basal rates and insulin needs during an intermittent fasting over a 24-hour period. Although you need to test your basal rates for the whole day, it is not recommended to fast during 24h straight. This is because the body triggers mechanisms such as hormones to compensate. A recommended way is to fast 3 times for 8 hours.
The recommended method is to suspend the loop, which will revert to your default background basal rate. Observe how your **BG** changes: if it is dropping, basal rate is too high. And vice versa.
An alternative method (may be more tricky) is to keep the loop running, and seeing how **IOB** changes. If **IOB** is negative, your basal rate is too high. And vice versa. Beware that this method relies on **ISF** to correct **BG**, and thus depends on other variables to be set reasonably well for it to be successful.
Another way of adjusting your basal rates is to watch the loop action during the night, when all COB have decayed. This method is particularly useful for children, when fasting is difficult or insulin needs change often. [Dr Saleh Adi from Tidepool](https://www.youtube.com/watch?v=-fpWnGRhLSo) provides useful ways on how to analyse overnight BG lines in order to optimise your basal rates.
When taking action on the result of your basal testing, changes in the **Profile** should be done 1 hour before the rise/drop. Repeat the test as necessary until you are comfortable with your **basal rates** settings.
(your-aaps-profile-insulin-sensitivity-factor)=
## Insulin sensitivity factor (ISF)
### Description
Коэффициент чувствительности к инсулину (иногда называемый корректирующим фактором) - это то, насколько 1 единица инсулина понижает ваш уровень гликемии.
**In mg/dL units:** If you have an **ISF** of 40, each unit of insulin will reduce your blood glucose by approx. 40 mg/dL (for example, your blood glucose will fall from 140 mg/dL to 100 mg/dL).
**In mmol/L units:** If you have an **ISF** of 1.5, each unit of insulin will reduce your blood glucose by approx. 1.5 mmol/L (for example from 8 mmol/L to 6.5 mmol/L).
From these examples you can see that the _smaller_ the **ISF** value, the less sensitive you are to insulin. So if you reduce your ISF from 40 to 35 (mg/dl) or 1.5 to 1.3 (mmol/L), this is often called strengthening your **ISF**. Conversely, increasing the **ISF** value from 40 to 45 (mg/dl) or 1.5 to 1.8 mmol/L) is weakening your **ISF**.
### Impact
A **lower / stronger ISF** (i.e. 40 instead of 50) means insulin drops your **BG** less per unit. This leads to a more aggressive / stronger correction from the loop with **more insulin**. If your **ISF** is too strong (small value), this can lead to low **BG**.
A **higher / weaker ISF** (i.e. 45 instead of 35) means insulin drops your **BG** more per unit. This leads to a less aggressive / weaker correction from the loop with **less insulin**. If your **ISF** is too weak (large value), this can lead to high **BG**.
**Пример:**
* **BG** is 190 mg/dL (10,5 mmol/L) and target is 100 mg/dL (5,6 mmol/L).
* So, you want a correction of `190 - 110 = 90 mg/dL` or `10,5 - 5,6 = 4.9 mmol/L`
* If `ISF = 30` -> `90 / 30 = 3` or `ISF = 1.63` -> `4.9 / 1.63 = 3`: 3 units of insulin
* If `ISF = 45` -> `90 / 45 = 2` or `ISF = 2.45` -> `4.9 / 2.45 = 3`: 2 units of insulin
An **ISF** that is too low (and therefore more aggressive, not uncommon) can result in ‘over corrections’, because **AAPS** calculates that the user needs more insulin to correct a high **BG** than actually required. This can lead to ‘roller coaster’ BG levels (esp. when fasting), as shown on the image below. In this circumstance, the **ISF** value should be increased in order to make **AAPS** less aggressive. This will ensure **AAPS** delivers smaller correction doses, and avoid over-correcting a high **BG** resulting in a low **BG**.
Conversely, an **ISF** set too high can result in under-corrections, meaning your **BG** remains above target – particularly noticeable overnight.
### How to set it
See the **figure below** for an example of how ISF values could be set in an **AAPS** profile.
Основной отправной точкой для определения ISF в дневное время является суммарная суточная доза (TDD) и правило 1700 (94). More detail is given in Chapter 7 of [“Think like a Pancreas”](https://amzn.eu/d/iVU0RGe) by Gary Scheiner.
1700 (если измеряется в мг/дл) или 94 (ммоль/л)/ TDD= примерно ISF.
Пример: TDD = 40 ед.
ISF приблиз. (мг/дл) = 1700/40 = 43
ISF приблиз. (ммоль/л) = 94/40 = 2,4
Assuming your basal levels are correct, you can test this by suspending the loop, checking **IOB** is zero, and taking a few glucose tablets to get to a stable ‘high’ level.
Затем введите предполагаемое количество инсулина (по текущему соотношению 1/ISF), чтобы прийти к целевой ГК.
Будьте осторожны, так как довольно часто величина слишком занижена. Слишком низкая ГК означает, что 1 ед опустит ГК быстрее, чем ожидалось.
(your-aaps-profile-insulin-to-carbs-ratio)=
## Insulin to Carb ratio (ICR)
### Description
The **ICR** is a measure of how many grams of carbohydrate are covered by one unit of insulin.
Some people also use **I:C** as an abbreviation instead of **ICR**, or talk about carb ratio : **CR**.
Например, соотношение инсулина 1 к 10 (1:10) означает, что вам требуется 1 ед. инсулина на каждые 10 граммов съеденных углеводов. Еда из 25г углеводов потребует 2,5 ед. инсулина.
If your **ICR** is weaker (higher value), perhaps 1:20, you would only need 0.5U of insulin to cover 10 g of carbs. Еда из 25г углеводов потребует 25/20 = 1,25 ед. инсулина.
It is common to have different **ICR** at different times of day due to hormone levels and physical activity. Many people find they have their lowest/strongest **ICR** around breakfast time because they tend to be more insulin resistant. So, for example, one adult user's **ICR** could be 1:8 for breakfast, 1:10 for lunch and 1:10 for dinner, but these patterns are not universal, and some people are more insulin resistant at dinner time, and require a stronger/smaller **ICR** then.
> **ПРИМЕЧАНИЕ:**
>
> В некоторых европейских странах для определения количества инсулина, необходимого для компенсации пищи, использовались т. н. хлебные единицы. В начале 1 хлебная единица равнялась 12г углеводов, позже некоторые стали считать ее как 10 г.
>
> В такой модели подсчетов количество углеводов было фиксированной величиной, а количество инсулина-переменной. ("Сколько инсулина нужно для того, чтобы компенсировать одну хлебную единицу?")
>
> When using **ICR** the amount of insulin is fixed and the amount of carbs is variable. ("Сколько грамм углеводов может компенсироваться одной единицей инсулина?")
>
> Пример:
>
> Bread unit factor (BU = 12g carbs): 2,4 U/BU -> You need 2,4 units of insulin when you eat one bread unit.
>
> Corresponding **ICR**: 12g / 2,4 U = 5,0 g/U -> 5,0g carbs can be covered with one unit of insulin.
>
> BU factor 2,4 U / 12g ===> IC = 12g / 2,4 U = 5,0 g/U

### Impact
A **lower / stronger ICR** means less food per unit, i.e. you are getting more insulin for a fixed amount of carbs. Может также назваться «более агрессивным». If your IC is too strong, you are getting too much insulin, this can lead to low **BGs**.
A **higher / weaker ICR** = more food per unit, i.e. you are getting less insulin for a fixed amount of carbs. Может также назваться «менее агрессивным». If your IC is too weak, you are getting less insulin than you need, this can lead to high **BGs**.
### How to set it
The **figure below** shows an example of a user's **ICR** and how it can be set in an **AAPS Profile**. When entering these values, we just enter the final part of the ratio, so an insulin-to-carb ratio of 1:3.5 is entered simply as “3.5”.
If after a meal has been digested and the **IOB** has returned to zero, your **BG** remains higher than before food, chances are your **ICR** is too weak (_i.e._ the number is too high and should be gradually lowered). Conversely, if your **BG** is lower than before food, **ICR** is too strong (_i.e._ the number is too small and should be gradually increased).
Assuming your basal rates are correct, you can test by checking if **IOB** is zero and that you are in-range, eating exactly known carbs, and take an estimated amount of insulin based on current insulin to carb ratio. Best is to eat food you normally eat at that time of day and count its carbs precisely.

### About the importance of getting your profile right
**Why should I try to get my profile settings right? Can’t the loop just take care of it?**
A hybrid closed loop _can_ attempt to make insulin delivery adjustments to minimise poor glycemic control that results from having incorrect **Profile** values. It can do this, for example, by withholding insulin delivery if you are going to hypo. However, you can achieve much better glycemic control if your **Profile** settings are already as close as possible to what your body needs. This is one of the reasons that **AAPS** uses staged objectives to move from open loop pumping towards hybrid closed loop. In addition, there will be times when you need to open the loop (sensor warmups, sensor failure _etc._), sometimes in the middle of the night, and you will want to have your settings right for these situations.
If you are starting with **AAPS** after using a different open or closed-loop pumping system, you will already have a reasonable idea of what values to use for basal rates (**BR**), insulin sensitivity factors (**ISF**) and insulin-to-carb ratios (**ICR**).
If you are moving from injections (MDI) to **AAPS**, then it is a good idea to read up on how to make the transfer from MDI to pump first, and plan and make the move carefully in consultation with your diabetes team. ["Pumping insulin"](https://amzn.eu/d/iaCsFa2) by John Walsh & Ruth Roberts and [“Think like a Pancreas”](https://amzn.eu/d/iVU0RGe) by Gary Scheiner are very useful.
### What causes high postprandial peaks in closed loop?
В первую очередь, проверьте значения скорости подачи базала и проверьте работу базы безуглеводным test'ом. If it is correct and your **BG** is falling to reach your target after carbs are fully absorbed, try to set an 'eating soon' temp target in **AAPS** some time before the meal or think about an appropriate pre-bolus time with your endocrinologist.
If your **BG** is too high after the meal and still too high after carbs are fully absorbed, consider decreasing your **ICR** with your endocrinologist. If your **BG** is too high while **COB** and too low after carbs are fully absorbed, think about increasing your **ICR** and an appropriate pre-bolus time with your endocrinologist.
### I'm stuck high and the loop does not bring me down
The possible reasons for **AAPS** not giving enough insulin are:
* **ISF** is not strong enough
* Basal might not be strong enough
* A security setting might kick in, such as **maxIOB**. Or **SMB** is disabled at this time, depending on your settings.
* Automation has been set up and has overridden **AAPS**.
### I have negative IOB, is this an issue ?
Negative **IOB** means the amount of absolute insulin (basal + bolus) in your body is less than the basal. It will cause **AAPS** to send more insulin as soon as the **BG** starts to rise, because it considers that insulin is missing, which can result in low **BG** later.
Here are some reasons why you may have negative IOB, and what action to take:
* a too strong basal: tweak your **Profile**
* too much bolus at the previous meal: tweak your **Profile** or check if you are bolusing at the right time.
* DIA too short, resulting in insulin stacking: tweak your **Profile**
* physical activity: next time, consider using a lower [Profile percentage](../DailyLifeWithAaps/ProfileSwitch-ProfilePercentage.md) during activity to account for increased sensitivity.

In this case, timeshift and percentage will be applied to the new local profile. Use the **Clone** button shown on line **1**.
You can now go to the [Profile tab](#your-aaps-profile-create-and-edit-profiles) to edit the newly created Profile.
(YourAapsProfile_Profile-backup)=
### Profile backup
Being a core setting of your looping system, your **Profiles** are highly sensitive and something you really don't want to lose.
* Your **Profiles** are stored in the **AAPS** database.
* If enabled, **Profiles** are also uploaded to Nightscout. The settings can be found in [NSClient Preferences > NSClient > Synchronization > Upload data to NS](#Preferences-nsclient).
* They are also part of [exported settings](../Maintenance/ExportImportSettings.md). So make sure to have a backup in a safe place.
### Editing Profiles from Nightscout
If enabled, **Profile** changes made directly in Nightscout can be received in **AAPS**. The settings can be found in [NSClient Preferences > NSClient > Synchronization > Receive profile store](#Preferences-nsclient).
This can be helpful when about to make major changes to a more extensive **Profile**. They can be entered more easily via the web interface, _e.g._ to manually copy data from a spreadsheet.
To do this, however, it is important to clone the whole **database record** consisting of several profiles in the Nightscout editor (blue arrow on the screenshot below). The new database records then carries the current date. After saving, the changed/new **Profile** can be activated in **AAPS** with a regular [Profile switch](../DailyLifeWithAaps/ProfileSwitch-ProfilePercentage.md).
