1. An adherent device to monitor a patient for an extended period, the device comprising:

  • a first adherent patch comprising a breathable tape with an adhesive coating to adhere the breathable tape to a skin of the patient, the adherent patch also comprising a plurality of electrodes affixed to the breathable tape and capable of electrically coupling to the skin of the patient; and

    an electronics module comprising electrocardiogram circuitry coupled to at least two of the plurality of electrodes and impedance circuitry coupled to at least two of the plurality of electrodes, the electronics module also comprising wireless communications circuitry coupled to the electrocardiogram circuitry and to the impedance circuitry to transmit to a remote server an electrocardiogram signal derived from an output of the electrocardiogram circuitry and a hydration signal derived from an output of the impedance circuitry;

    wherein the electronics module is coupled to the breathable tape to support the electronics module when the tape is adhered to the patient;

    and wherein the electronics module is separable from the adherent patch such that the electronics module can be reused with a second adherent patch to provide monitoring for an extended period.
