Understanding Core OpenAPS Settings

To jest heart of OpenAPS consists of several interlinked parameters that govern insulin delivery decisions. Before you adjust anything, it 's essential two know what each setting does, how they interact, and d whatt thee numbers mean.

Insulin Sensitivity Faktor (ISF)

ISF tells thee system hole much one unit of insulin lowers your blood glucose. For example, an ISF of 40 means 1 unit drops glucose by 40 mg / dl. Thi value can vary through out the day due to circadian rhythms, activity, and incore cycles. In OpenAPS, ISF is stores a time-based set of values (e.g., different settings for morning, afnoon, and night).

Karbohydrat Ratio (Carb Ratio)

Carb ratio definies hom many grams of carbohydrate are covered by one unit of insulilin. A starting point might be 10 g / U, but many meille need ratios that different for breakfast, lunch, and dinner due to variations in insulin resistance through out the e day. Increate carb ratios lead to posto-meal spikes (ratio too high - not enough insulin) or earlposte-meal lows (ratio too low - too much insulin).

Step-by- Step Customization Process

Follow this systematic approach to modify your OpenAPS settings. Always tect one change at a time and allow 48- 72 hour to evocate each recrument. Rushing leads to confusion and risk.

1. Backup Your Configuration

Copy your entire rig 's configuation directory. Run present 1; Department 1; FLT: 2 presentation 3; Department 3; or download via te e web interface. Store thee backup off-device in case you need to revert quicklile.

2. Adjuszt Basal Rates First

Basal rates are te foundation of thee system. If your basal profile is wrong, all automate correcations will be built on a shaki base. To tect basal creasy, run OpenAPS in low-basal mode (or suspend) for an overnight fast. If glucose rises more than 10 mg / dL, your basal is too low; if it falls, too high. Adjust the specific time period 10- 15% and e e e e-tett. Repeuntil overt thalls (+ 5).

3. Tone Insulin Sensitivity Faktor

After basal is correct, evaluate ISF. Look at correction boluses: wheren your glucose is high and thee system delivers a bolus, compare the predicted drop with thee actual drop. If thee system confidently than sub-correctes (glucose stays hiser than prevented), your ISF number is too high (i.e., each unit haless effect than assumed); inthee ISF value. If it over-correcuts, intrione thee ISe value. Many users need f ft dift parts of thee day. Usnightscout 's nexet; Deviation; Devit; devit net; et; et systematic.

4. Set Carbohydrate Ratios

Carb ratios are often thee most variable. Analyze 5- 7 days of meal data. For each meal, distard pre-meal glucose, carbs entered, and the glucose at 2 and4 hour pot-meal. If you see a consistent rise after breakfast, that ratio is likely too high (not enough insulin). If you go low before the next meal, thee ratio is too low.

5. Konfiguracja Target Glucose Range

Set your low and high targets realistically. Most difficults aim for 100- 1110 mg / dL. If you have frequent lows (especially overnight) or hypoglycemia unwaures, raise both precises to 110- 130 mg / dL. You can also set temporary precis: for exercise, pre-set 140 mg / dL; for sleep, 120 mg / dL. Usie thee precipendivation 1; FLT: 3 contribunal 3; profile in Nightscout te these changes.

6. Set Maximum Basal Rate andMax IOB

Max basal rate should be 2- 3 times your highest scheduled basal rate. Start with 2 × tu be safe. Max IOB should d initially be low - np., 2 units - and only increase after you see how the systeme behaves during high-correct previos. Note: Max IOB includes only insulin deliveid by the loop (temp basals andd SMB), nott manual boluses u give for meals.

7. Autouczulenie (Auto-Sens)

Enable 1; Xi1; FLT: 4; Xi3; in your preferences. This dinamically adducts basal, ISF, and target based on recent glucose deviations. It helps compensate for daily flucations like illness, stress, or activity changes. Monitor how much auto-sens adducts (you can see thee autsens ratio in Nightscout).

Advanced Customizations for Experienced Users

Super Micro Bolus (SMB)

SMB enables the system to deliver small boluses of rapid-acting insulin every 5 minutes, nott just temporary basal adjustments. This can flatten poct-meal peaks andd respond quiquly ty ty rising glucose. However, it prevenes risk of insulin stacking.

Temp Targets for Activity andd Sleep

Set up multiple temporary target profiles that you can activate via Nightscout or a mobile app. For example:

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Activity: Xi1; Xi1; FLT: 1 Xi3; Xi3; Xi3; 140 mg / dL for 2 hour - reduces insulin delivy to prevent lows during exercise.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Sleep: Xi1; Xi1; FLT: 1 Xi3; Xi3; 120 mg / dL low target - reduces overnight hypoglycemia risk.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Pre-meal: Xi1; Xi1; FLT: 1 Xi3; Xi3; 90 mg / dL low target - allows more aggressive correction before a meal.

You can automate these wigh IFTTT or custem scripts that trigger based on calendare events or heart rate data.

Usie Nightscout 's quentiquit; Daily Profiles quentiquentes; overlay to see if thee rise starts before dawn (dan phenonoun) or after midnight. Adjuss the basal segment that precedes the rise. Also consider ISF - if dan phenonoun is strong, you may need a tempour target of 90 mg / dFor before or a more agressive ISF overnight.

Recurring Post-Meal Lows

Niski poziom 2-3 godziny, przy czym poziom narażenia wynosi około 2-3 godziny, a poziom narażenia na działanie glukozy wskazuje na to, że w przypadku braku takiego działania, należy zmniejszyć poziom narażenia, a w przypadku braku takiego działania - o 1-2 g / U. Also check if your ISF is too aggressive - if correction s after meals overshoot, zwiększając ten poziom ISF number (make each unit less powerful).

System Over-Corritting for High Glucose

Jeśli ta system dostarcza too much insulin when you go high, your ISF is probable too low (thee number is too small). Increase ISF (e.g., frem 40 tu 50) so each unit has less of an effect. Also verify your max IOB - if it 's set too high, the system can stack more insulin than needed. Reduce max IOB temporarily.

Too Many Suspensions (Low Basals)

If you see frequent zero-tempp basals (suspensions), your basal rates may be too high, or your max IOB may be too high for your needs. Lower the basal rate in thee affected time block. Also check your temp target - if you 're using a lower target, the system will cut insulin more aggressively.
