  • Patent number: 11951284
    Abstract: Apparatuses and methods for transitioning to sleep mode or otherwise modified glucose target range in automated insulin delivery systems. For example, sleep mode can include a lower glucose target and/or lower and narrower glucose target range because of fewer variables that affect glucose values during sleep such as eating and exercise. Due to increased stability provided by the sleep mode target range, it is desirable to transition to the sleep mode target range as quickly as possible, while ensuring the transition is done safely and does not risk low glucose or hypoglycemia by too quickly switching to the lower and narrower target range. Systems and methods disclosed herein therefore provide various approaches for safely and quickly transitioning to sleep mode or other modified target ranges in order to improve time in range by being more aggressive to get to the lower sleep mode or other target faster without risking hypoglycemia.
