1. A system for weaning a patient from mechanical ventilation (MV), the system comprising:

  • a ventilation device; and

    a controller comprising an interface module configured to receive two or more measured patient parameters, wherein at least one of the two or more measured patient parameters comprises a CO2 related parameter, wherein said controller is further configured to compute an Integrated Pulmonary Index (IPI) value based on the two or more measured patient parameters and to provide a signal to said ventilation device, based on the computed IPI value, wherein said signal adjusts one or more weaning related parameters in said ventilation device;

    wherein the IPI is computed by;

    (a) characterizing a first measured patient parameter of the two or more measured patient parameters based on a comparison of the first measured patient parameter against a first reference value;

    (b) characterizing a second measured patient parameter of the two or more measured patient parameters based on a comparison of the second measured patient parameter against a second reference value; and

    (c) computing the IPI value based on values associated with each of the characterized first and second measured patient parameters, wherein a weighting factor applied to the value associated with the second characterized measured patient parameter is influenced by the characterization of the first measured patient parameter.
