1. A method for operating a ventilator system having a ventilator and a connection system for, when connected to a patient, conveying gas to and from that patient, said method comprising the steps of:

  • setting a plurality of operational parameters for a test gas pulse;

    storing said operational parameters as a first dataset;

    delivering a test gas pulse having said operational parameters to said connection system, and thereby producing a resulting gas pulse response;

    measuring parameters of said resulting gas pulse response;

    storing the measured parameters of said resulting gas pulse response as a second dataset; and

    forming a third dataset based on said first dataset and said second dataset comprising, for at least one flow path within said ventilator system, information selected from the group consisting of a static influence of said at least one flow path, a dynamic influence of said at least one flow path, and properties of said at least one flow path.
