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： A device and a process for determining the change in the functional residual capacity (FRC) in a simple manner. Based on a first respiration phase for mechanical respiration, a recruitment maneuver is performed for this during a second respiration phase, and respiration is switched back to mechanical respiration during a third respiration phase. Reference values Uref/1, Uref/3 are formed from the end-expiratory values of the impedance measured signals U during the first respiration phase and the third respiration phase, and the difference ΔU (ΔFRC) between the reference value Uref/3 of the third respiration phase and the reference value Uref/1 of the first respiration phase is an indicator of the change in the functional residual capacity of the lung of the test subject.

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 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. A process is also provided for regulating a respirator and for respirating a patient.
摘要翻译：用于向患者提供呼吸气体的装置，其中从外部施加的初始高初始压力Paw（t = 0）一旦肺部被吸入，通过控制电路自动降低到较低的吸气压力Paw（t）内部压力Plung（t）威胁超过预定的肺部目标压力Plung，soll。因此根据本发明排除了由呼吸引起的肺的过度充气。此外，该装置还允许用呼吸气体快速填充肺，并且因此可能达到相对较长的呼气阶段。还提供了一种用于调节呼吸器和呼吸患者的过程。

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： A process and a device is presented with an electro-impedance tomography (EIT) system (2), with a computing unit (4) and with a respirator (1) for gentle mechanical lung ventilation especially in case of atelectases following surgical procedures. A first image of the healthy lungs is first recorded prior to anesthetization by means of the EIT system (2) and the total area and/or the spatial distribution of ventilated lung areas are determined from the image values by means of the computing unit (4). Second or additional status images are recorded after assumed lung damage and the total area and/or the spatial distribution of ventilated lung areas are determined. The total areas and/or the spatial distribution of the ventilated lung areas from the first and second or further status images are compared by means of the computing unit (4) and analyzed for the presence of lung areas that have no or reduced ventilation due to atelectases. The information on the presence, the extent and/or the spatial distribution of atelectases is sent by the EIT system (2) to the respirator (1) so that the respiration pressure is increased step by step by the respirator (1) as a function of the status image or the currently determined status images until the current image of the lung status corresponds to the first status image 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.
