Abstract: A device and a method for artificial respiration in emergencies are proposed. The device comprises respiratory mask (40) which can be placed onto the nose and mouth section of a person to be provided with artificial respiration, a mouth section mouthpiece (41), through which respiratory air from an aider can be supplied, a flow tube (2) disposed between the respiratory mask (40) and the mouthpiece (41), which flow tube forms a continuous flow channel for the supplied respiratory air from the mouthpiece (41) to the respiratory mask (40), at least one sensor (10) disposed in the flow channel of the flow tube (2), which sensor measures parameters of the gases flowing through the flow channel, a processor disposed on the flow tube (2) and an output device (124). Here, the processor processes the mass or volumetric flow registered by the flow sensor (19) to form an output signal. The output device (124) emits the output signal.

Abstract: The invention relates to a device for and method of monitoring compressions in a cardiac massage on a person in a medical emergency situation. The device is equipped with a flow tube (2, 202), which exhibits a continuous flow channel for air, with at least one flow sensor (10) for determining mass or volumetric flow arranged in the flow channel of the flow tube (2, 202), and/or with a vital signs sensor arranged on the flow tube, by means of which a proportion of oxygen and carbon dioxide can be determined, with a processor that produces a characteristic output signal for penetration depth from the mass or volumetric flow determined and/or from the proportion of oxygen or carbon dioxide detected, and with an output device (124, 224) that issues the output signal.

Abstract: In order to make a process available for the production of a multi-layer electrode or electrode assembly, with which an electrode or electrode assembly optimized for the respective use may be produced in a simple and, in particular, inexpensive manner it is suggested that a first layer be rolled onto a carrier and at least one additional function layer be produced by spraying on a powder.

Abstract: In order to create a device for testing a membrane electrode assembly, by means of which fabricated membrane electrode assemblies can be tested in a non-destructive manner, a first contact device is provided for bringing a first electrode side of the test object into electrical contact, a second contact device is provided for bringing a second electrode side of the test object into electrical contact, the first and second contact devices being electrically conductive at least in the contact area, and the first contact device and/or the second contact device having a plurality of electrically conductive contact segments spaced from one another, and a conductivity measuring device is provided for measuring the conductivity of the test object segmentwise in a location-resolved manner.
