Insulin adaptation and safety monitoring for sick day management
Disclosed are an apparatus, system, processes, and techniques for adapting drug delivery and monitoring a user's safety when the user is experiencing a sick day. A processor may be operable to provide a graphical user interface that presents a sickness mode prompt for a user to indicate that the user or another person with diabetes is sick. The graphical user interface may present symptoms from which a user may select. Based on the selection of symptoms, glucose measurement values, and/or ketone measurement values, a response to the user's indication of sickness may be provided.
1 . A controller of a drug delivery system, comprising:
a processor operable to execute programming instructions;
a user interface including a display and user input circuitry;
a memory operable to store the programming instructions; and
a communication circuitry coupled to the processor operable to receive and transmit wireless communication signals, wherein the processor, when executing the programming instructions, is operable to:
receive an indication that a user is experiencing a sickness;
based on the indication, adjust one or more settings of a medication delivery algorithm;
cause delivery of a liquid drug based on the adjusted one or more settings;
evaluate a glucose measurement value with respect to a hyperglycemic threshold;
evaluate a ketone measurement value with respect to a selected ketone level threshold of a plurality of ketone level thresholds; and
increase a total daily insulin value based on the evaluation of the glucose measurement value and the evaluation of the ketone measurement value.
2 . The controller of claim 1 , wherein the processor is operable to:
generate a prompt with a list of symptoms of the sickness; and
receive a selection from the user from among the list of symptoms.
3 . The controller of claim 1 , wherein the processor is operable to:
receive a glucose measurement value from a glucose sensor via the communication circuitry, or
receive a ketone level reading from a ketone sensor via the communication circuitry.
4 . The controller of claim 1 , wherein the processor, when evaluating the ketone measurement value with respect to the selected ketone level threshold from the plurality of ketone level thresholds, is operable to:
determine whether the ketone measurement value is greater than the selected ketone level threshold; and
based on the determination, generate a ketone measurement value indication.
5 . The controller of claim 1 , wherein the processor is further operable to:
adapting a basal dosage, bolus dosage, and a delivery schedule based on the increased total daily insulin.
6 . The controller of claim 5 , wherein the processor, when adapting the basal dosage, is operable to:
increase the basal dosage by a selected percentage of a nominal basal dosage setting.
7 . The controller of claim 6 , wherein the processor, when evaluating the ketone measurement value with respect to the selected ketone level threshold from the plurality of ketone level thresholds, is operable to:
determine whether the ketone measurement value is greater than the selected ketone level threshold; and
based on the determination, generate a ketone measurement value indication.
8 . The controller of claim 6 , wherein the processor, when adapting the bolus dosage, is operable to:
increase the bolus dosage based on a bolus delivery calculation that utilizes the increased total daily insulin.
9 . A controller of a drug delivery system, comprising:
a processor operable to execute programming instructions;
a user interface including a display and user input circuitry;
a memory operable to store the programming instructions; and
a communication circuitry coupled to the processor operable to receive and transmit wireless communication signals, wherein the processor, when executing the programming instructions, is operable to:
receive an indication that a user is experiencing a sickness;
based on the indication, adjust one or more settings of a medication delivery algorithm;
cause delivery of a liquid drug based on the adjusted one or more settings;
evaluate a glucose measurement value with respect to a hypoglycemic threshold range;
evaluate a ketone measurement value with respect to a selected ketone level threshold of a plurality of ketone level thresholds; and
reduce a total daily insulin value based on the evaluation of the glucose measurement value and the evaluation of the ketone measurement value.
