ABSTRACT:
An apparatus for producing data concerning the respiration-related movements of the abdominal wall and/or the thorax of a person. The device comprises at least one first pair of sensor units (12, 14), which are configured for detachably fixing on the skin in an area of the person's thorax or abdomen, a first distance (1) apart; and a measuring device (20) which is connected to said first pair of sensor units and which is configured for detecting signals of the sensor units that can be evaluated electrically and for producing a distance signal corresponding to the first distance (1) and to changes in the same. Connected downstream of the measuring device is an evaluation device (22, 28) which is configured for evaluating pulsed and/or wave-shaped changes in the first distance signal, in such a way that periodical signal changes of a frequency in the range of 0.05 to 0.1 Hz are detected, distinguished from the periodical changes in the first distance signal that are due to the human heartbeat in terms of frequency, amplitude or signal shape and output in the form of a respiration display signal that can be displayed and further processed electronically.
