Abstract: 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.

The valve means (6) is cyclically reversed by the registering device (5) in two phases such that depending on the filling level of the breathing gas reservoir (4), the inspiration line (7) is first connected with the compressed air reserve (1) and the expiration line (8) with the breathing gas reservoir (4) during a first phase until the filling level of the breathing gas reservoir (4) reaches an upper reversing point for the valve means (6), so that the inspiration line (7) is connected with the breathing gas reservoir (4) and the expiration line (78) with the ambient air (11) during a second phase until the filling level of the breathing gas reservoir (4) reaches a lower reversing point for the valve means (6) and the latter is again reversed as in the first phase.

Abstract: A process for determination of one component of very low concentration in a test gas, which is guided in a supply line for concentration of the component across a sample collector, whose amassed quantity of samples is relinquished to a detection sensor. The arrangement makes available a measurement signal even during the collection of the sample. It also makes even the individual components of a multicomponent test gas detectable and a component-specific cross sensitivity of the detection sensor controllable. For this, the following process steps are provided: the test gas is first guided across the detection sensor 3 and then across the multistaged sample collector 7 having arrangements for separation of the several components; then after interruption of the supply of test gas, each individual stage 4, 5 and 6 separately relinquishes its separated component to the detection sensor 3.

The control and evaluating unit (20) cooperates with the selector switch (60) such that two electrodes each are supplied with an alternating current from an AC power source (22) and the detected analog voltage signals of the other electrodes are processed in order to reconstruct therefrom the impedance distribution of the body in the plane of the electrodes, wherein a symmetrical AC power source is used to reduce common-mode signals.

Abstract: 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.

The control and evaluating unit (20) cooperates with the selector switch (60) such that two electrodes each are supplied with alternating current from an AC power source (22).

A symmetrical AC power source (22) is used to reduce common-mode signals. To make it possible to suppress errors due to common-mode signals, provisions are made for the control and evaluating unit (20) to be set up for making available an additional common-mode signal at an output during an adjusting mode of operation and to send it to the body via common-mode signal electrodes (4, 90) that can be placed on the body. The control and evaluating unit (20) is prepared, furthermore, to adjust the measuring amplifier (62) according to value and phase for each electrode pair connected by the selector switch (60) such that the common-mode signal at the output of the measuring amplifier (62) is minimized, and the adjusted parameters are stored for each electrode pair.
