1. Process for determining mechanical properties of a respiratory system of a patient connected to a respiration device, the process comprising the steps of:

  • performing a plurality of occlusions of an airway of the patient during a plurality of breaths, each of said occlusions occurring in a separate one of said plurality of breaths, each of said occlusions also occurring at a different point in a respective one of said plurality of breaths;

    determining respiratory flow and volume of the patient at a beginning of said each occlusion;

    measuring airway pressure during said each occlusion;

    determining a change occurring over time in said airway pressure during a measurement time within said each occlusion;

    determining a change occurring over time in muscle pressure of the patient from said change in airway pressure.
