Method and apparatus for controlling at least one ventilation parameter of an artificial ventilator for ventilating the lung of a patient in accordance with a plurality of lung positions

A controlling method to control at least one ventilation pressure of an artificial ventilator for ventilating an artificially ventilated lung of a patient in accordance with a plurality of lung positions, the patient lying in a nursing bed and the position of the artificially ventilated lung is moveable by a position actuator, comprising the steps of:

• a) obtaining lung status information which is based on at least two supporting points of a first status of the artificially ventilated lung in accordance with a first lung position and a second status of the artificially ventilated lung in accordance with a second lung position,
• b) moving the artificially ventilated lung by the position actuator to a defined lung position,
• c) controlling of at least one ventilation pressure in accordance with the defined lung position and in accordance with the lung status information related to said defined lung position.

A positioning method to control the change of a position of an artificially ventilated lung of a patient, the patient lying in a nursing bed and the position of the artificially ventilated lung is changeable by a corresponding position actuator, comprising the steps of:

• a) providing a periodical controlling signal having a distribution of a plurality of position periods and/or of a plurality of amplitudes,
• b) controlling the position actuator by said periodical controlling signal.

A recording apparatus to record a status of an artificially ventilated lung of a patient lying in a nursing bed in accordance with a plurality of lung positions, comprising:

• a) a position actuator to move the artificially ventilated lung to a defined lung position,
• b) determining means to determine the status of the artificially ventilated lung, and
• c) recording means to record the status of the artificially ventilated lung in accordance with the defined lung position.
