I have Type 1 Diabetes (T1D) and use a semi-closed loop system, which includes the Libre 2 sensor with XDrip and the Omnipod Dash, managed by AAPS.
AAPS (unlike the Tandem T
, which I’m less familiar with) uses a more sophisticated algorithm to calculate the required insulin, considering several factors:
- Blood sugar levels received via XDrip from the Libre 2 sensor.
- A profile that includes:
- - The basal rate per hour for each time slot
- - The insulin-to-carb ratio
- - The target blood sugar range
- Automatically calculated insulin sensitivity.
- Insulin on board (remaining active insulin), calculated using a curve to estimate how much insulin is still active after injection.
- Carbs on board, with AAPS tracking active carbs over time.
