1. At least one non-transitory computer readable medium having stored thereon instructions that are configurable to cause at least one processor to perform a method comprising:
operating a medical device to deliver a fluid to a body of a user in accordance with an operating mode using initial values for control parameters of the operating mode, wherein the fluid influences a physiological condition of the user;
identifying a different fluid type associated with the fluid from among a plurality of possible fluid types, the different fluid type having pharmacokinetics characteristics different from a previous fluid type;
in response to identifying the different fluid type, updating the initial values for the control parameters to updated values different from the initial values and the updated values reflecting the pharmacokinetics characteristics of the different fluid type, wherein the updated values comprise an updated gain coefficient value for a closed-loop operating mode; and
thereafter operating the medical device in accordance with the operating mode using the updated values for the control parameters of the operating mode by generating dosage commands to deliver the fluid to regulate the physiological condition of the user to a target value using the updated gain coefficient value.
