AAPS analysis: spotting problems in your settings
With type 1 diabetes, AAPS helps automate part of the daily routine, but its performance depends heavily on its settings. Rather than changing parameters blindly, look for recurring patterns: when glucose consistently rises, when corrections have little effect, and when the system acts too aggressively.
Which signals to look for in AAPS
- Basal insulin and automatic corrections — whether glucose stays steadier without unnecessary rises, frequent falls or constant intervention by the system.
- ICR — whether peaks after similar meals match the expected calculation, and whether the carbohydrate ratio may need review.
- ISF — whether the charts show predictable corrections, without too little effect or unnecessary sharp falls.
- Recurring patterns — whether the same pattern occurs over several consecutive days, rather than changing AAPS settings after a single episode.
How to review AAPS charts without jumping to conclusions
- Review several similar days together: rises or falls without food are better assessed as a series, rather than from one difficult day.
- Compare similar meals separately: if the same food repeatedly produces a similar peak, this is a reason to review ICR carefully.
- Assess corrections across several episodes: too little effect or repeated sharp falls may suggest that ISF needs review.
- Do not change AAPS settings immediately after one problem: first look for a recurring pattern by time of day, food and response to corrections.
What to do after this review
After this review, compare your observations with Nightscout data and adjust AAPS settings gradually: one parameter at a time, checking several similar days rather than a single chart.
