摘要： A device for supplying a patient with breathing gas, in which an initially high initial pressure Paw(t=0) applied from the outside is automatically lowered by means of a control circuit to a lower inspiratory pressure Paw(t) as soon as a pulmonary internal pressure Plung(t) threatens to exceed a predetermined pulmonary target pressure Plung,soll. Overinflation of the lungs due to the respiration is thus ruled out according to the present invention. The device permits, moreover, rapid filling of the lungs with breathing gas and makes thus possible a comparatively long phase of expiration.

摘要： A process with a corresponding device for lung ventilation involves recording an image of the lung status with an electric impedance tomography (EIT) system (2) and the total area of ventilated lung areas is determined by a computing unit (4) from all image values, subsequently divided into at least two lung areas and the extent of the homogeneity of the ventilated lung areas is determined by comparison of the impedance changes within these areas. In case of a homogeneity rated as being too low, the respiration pressures are increased step by step by means of the respirator (1) and the respiration pressure at which the greatest possible homogeneity is obtained from subsequently determined status images is determined by means of the EIT system (2). The respiration pressure is subsequently lowered again by the respirator (1) until the computing unit (4) detects a reduction in the homogeneity of ventilated lung areas, so that the respiration pressure is subsequently increased again by means of the respirator (1) to the last value at which no reduction in the homogeneity of the ventilated lung areas occurred.

摘要： The invention relates to a method for recognizing the respiratory phases of a patient for controlling a ventilating apparatus. The time-dependent trace of a signal, which represents the respiratory flow curve and is emitted by a signal device, is determined and from this trace, a trigger criterium is obtained for the switchover of the ventilating apparatus from the expiration phase into the inspiration phase and/or from the inspiration phase into the expiration phase. The method is improved in that even for chronically obstructive patients, a reliable and early recognition of the inspiration and expiration attempts is possible. A significant increase of the slope of the respiratory flow curve between each two zero crossovers of this curve is used as a trigger criterium.

摘要： A respirator for breath-supporting respiration has improved sensitivity of triggering breathing support. A pre-inspiratory inspiratory gas flow is set, which flows off via the expiration valve (9). The closing pressure pv of the expiration valve is measured with a pressure sensor (11) in the process. The gas flow is increased in case of an inspiratory effort of the patient to the extent that the closing pressure pv of the expiration valve (9) is restored. Breath support is generated when the difference between the preset gas flow and the gas flow that is needed to maintain the closing pressure pv at a constant level exceeds a predetermined threshold value.

摘要： An electro-impedance tomography (EIT) system (2), with a computing unit (4) and a respirator (1) is described for gentle mechanical lung ventilation especially in case of atelectases. The presence, the extent and/or the spatial distribution of atelectases is detected by the EIT system (2) and sent to the respirator (1) so that the respiration pressure is increased step by step by the respirator (1) until the current image of the lung status corresponds to a first status image of healthy lungs or comes close to it with minimal deviations. The respiration pressure is subsequently reduced again step by step by the respirator (1) until the computing unit (4) detects a reduction of the ventilated lung areas and the respiration pressure is subsequently increased again by means of the respirator (1) to the last value at which no change occurred in the ventilated lung areas.

摘要： A process is provided for controlling at least one parameter of the breathing gas supply of a respirator with a patient connected to it as well as to a corresponding control device. The respiration pressure, the breathing gas flow generated by the respirator as well as the respiration rate may be used as parameters. The process presents the advantage that the control of the current respiration needs of the patient are taken into account by the muscle pressure (PMUS), i.e., the percentage of the airway pressure caused by the patient's own effort, being maintained at a value close to zero. An airway pressure (PAWC) is first calculated for this purpose from previously measured values for the airway pressure (PAW) and the breathing gas flow (d/dt V) and the mechanical parameters resistance (RL) and compliance (C) of the patient's lungs, which were determined therefrom, and this is subsequently compared with the actually measured value for the airway pressure (PAW). The at least one parameter of the breathing gas supply of the respirator is subsequently controlled on the basis of the comparison between PAWC and PAW, expressed as the muscle pressure PMUS=PAWC−PAW.
