1. A method of obtaining an improved estimate of respiration rate from two or more cardiac-derived signals representative of respiration comprising the steps of:

  • converting the cardiac-derived signals into the frequency domain to generate respective frequency response signals representing the spectral content of the cardiac-derived signals;

    point-by-point multiplying together the frequency response signals and identifying the improved estimate of respiration rate from one or more spectral peaks in the product function resulting from the multiplication.
