1. A method of monitoring a sleep apnea and/or hypopnea of a patient, the method comprising:

  • adhering an adhesive patch to a skin of the patient to couple at least one electrode to the skin of the patient, wherein the adhesive patch supports the at least one electrode, impedance circuitry, a processor, and wireless communication circuitry;

    measuring an impedance signal of the patient with the impedance circuitry coupled to the at least one electrode;

    processing the impedance signal with the processor to determine a respiration rate;

    processing the impedance signal with the processor to determine extracellular fluid of the patient, sufficient to monitor hydration status, wherein the extracellular fluid is determined using impedance measurements with a frequency from about 0.5 kHz to about 20 kHz;

    communicating via the wireless communication circuitry the respiration rate and the hydration status to a remote monitoring center;

    detecting at the remote monitoring center the sleep apnea and/or hypopnea of the patient in response to the communicated respiration rate;

    determining a decompensation risk at the remote monitoring center based on the detected sleep apnea and/or hypopnea and the hydration status.
