1. A method comprising:

  • detecting a thoracic impedance signal of a thorax of a subject;

    detecting a blood resistivity signal; and

    determining a thoracic fluid indication using the thoracic impedance signal, the determining the thoracic fluid indication including using the blood resistivity signal to reduce or eliminate an effect of a change in the blood resistivity on the thoracic fluid indication.
