Determination of adjustments to fluid delivery settings
Disclosed herein are techniques related to determination of adjustments to fluid delivery settings. In some embodiments, the techniques may involve accessing insulin delivery data for a user of an insulin delivery device. The insulin delivery data may be indicative of an amount of insulin delivered by the insulin delivery device to the user during a time period. The techniques may also involve analyzing the insulin delivery data to generate an updated insulin sensitivity factor (ISF) value. The techniques may further involve generating, based on the updated ISF value, a recommendation to adjust an ISF value of the insulin delivery device. Additionally, the techniques may involve causing adjustment of the ISF value to the updated ISF value in accordance with the recommendation.

generating an updated insulin sensitivity factor (ISF) value based on an average total daily dose (TDD) of insulin determined using the insulin delivery data collected during the closed-loop mode;
generating, based on the updated ISF value, a recommendation to adjust an ISF value for a manual mode of the insulin delivery device, wherein the ISF value for the manual mode is separate from an ISF value for the closed-loop mode; and
