1. A method for measuring respiration function of a living organism, comprising the steps:

  • placing said living organism in a constant volume plethysmograph chamber;

    obtaining a first input signal from at least one pressure sensor indicative of a change in lung volume during breathing by said living organism;

    obtaining a second input signal from a sensor indicative of airflow through the respiratory system of said living organism during the change in lung volume; and

    processing said first input signal and said second input signal to calculate a third signal indicative of respiratory restriction of said living organism.
