ABSTRACT:
In a ventilator system and a method of operating the ventilator system, the ventilator system has a ventilator and a connection system for connecting the ventilator system to a patient. Parameters for a respiration gas pattern are set on the ventilator. Due to the influence of the connection system on the respiration gas pattern, the generation of the respiration gas pattern needs to be calibrated in order to ensure that the set respiratory gas pattern is delivered to the patient. In order to obtain calibration factors a test gas pulse is generated by an inspiration system before connecting the patient. Measurements of the test gas pulse are made with parameter meters at different locations in the connection system. The parameters for the test gas pulse, as well as the measured parameters are stored in different data sets. By synchronizing and subtracting measured parameter data sets from the set parameter data set, calibration factors are obtained.
