1. A method for determining a respiration rate value from a patient, comprising the following steps:

  • (a) measuring a first time-dependent signal by detecting a modulated electrical current passing through the patient'"'"'s torso;

    (b) measuring a second time-dependent signal by detecting respiration-induced movements in the patient'"'"'s torso with at least one motion sensor;

    (c) determining a motion-related event not related to the patient'"'"'s respiration rate value by processing signals from at least one motion sensor; and

    (d) collectively processing both the first and second time-dependent signals to determine a value for respiration rate corresponding to a period when at the motion-related event is below a pre-determined threshold.
