1. A method of infusing a fluid into a body of a user comprising:

  • operating a physiological monitoring device carried on the exterior of the body of the user, to perform the operations of;

    measuring an output signal produced by a sensor, the output signal being a function of a concentration of an analyte in the user;

    determining a first amount of time that has elapsed since the sensor provided the output signal;

    determining whether the first amount of time exceeds a predetermined amount of time; and

    , if the first amount of time does not exceed the predetermined amount of time,calculating an amount of the fluid to be infused into the user'"'"'s body based upon the output signal; and

    transmitting a first set of data with a first communication circuit enclosed within a first housing of the physiological monitoring device, the first set of data being indicative of the amount of the fluid to be infused, the first set of data further including an identifier associated with the amount of fluid to be infused;

    wherein the amount of fluid to be infused into the user'"'"'s body based upon the output signal is not calculated if the first amount of time exceeds the predetermined amount of time; and

    operating a medication infusion device carried on the exterior of the body of the user, to perform the operations of;

    receiving the first set of data with a second communication circuit enclosed within a second housing of the medication infusion device carried on the exterior of the body of the user;

    verifying the identifier to ensure the amount of fluid to be infused has not already been administered; and

    activating a drive mechanism to infuse the fluid in accordance with the first set of data.
