| 摘要 |
The invention relates to a method for controlling the breathing gas flow of a ventilator for assisted or controlled ventilation of a patient as a function of the tracheobronchial airway pressure of the patient, having a ventilator tube, such as a tracheal tube or tracheostomy tube, that can be introduced into the trachea or the patient and subjected to the breathing gas and that is equipped with an inflatable cuff and at least one lumen that is continuous from the distal end of the tube to the proximal end of the tube, and with an apparatus for detecting the airway pressure, in which the tracheobronchial airway pressure is ascertained by continuous or intermittent detection and evaluation of the intra-cuff pressure prevailing in the cuff of the tube inserted into the trachea, and the breathing gas flow of the ventilator is controlled as a function of the intra-cuff pressure detected. |
