    Abstract: The invention is directed to a measuring cell for an electrochemical gas sensor having an electrolytic chamber and a measuring electrode as well as a counter electrode. In the direction facing the ambient, the measuring electrode includes a diffusion membrane as well as a diffusion barrier. The diffusion barrier is made of a material which is a good conductor of heat and is provided with a plurality of passages. A temperature-sensitive element is provided in the immediate proximity of these passages and faces toward the ambient. With this configuration, the temperature dependency of the diffusion capacity of the gas sample passing through the diffusion barrier can be included in the processing of the signal indicative of the measurement.

    Abstract: The invention is directed to an apparatus for sensing a gaseous component in air and includes a housing having a flushing chamber through which an air sample can flow via a closeable inlet and a closeable outlet. The sensor is mounted in a measuring chamber above the flushing chamber and is hermetically sealed from its ambient not only during the time that the flushing chamber is flushed with the air sample; rather, and most important, during the measuring operation itself in order that any influences from a diffusion of the ambient air into the measuring chamber is prevented. For this purpose and to determine the sample quantity diffusing into the measuring chamber at the beginning of a specific period of time, the inlet as well as the outlet of the flushing chamber is closed while at the same time the diffusion passage interconnecting the two chambers is opened. After the time period has run, the diffusion passage is again closed.

    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.

    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.
