Abstract: An apparatus (1) for providing cardiopulmonary resuscitation by applying compressions to a chest of a patient (P). The apparatus (1) comprising a chest compression unit (10), in particular comprising automatic actuation, at least one band (20) to be passed around the patient's chest for maintaining the chest compression unit (10) in position on the patient's chest. At least one end of the band (20) is releasably connectable to the unit (10) or another band. The apparatus (1) is designed for pushing the band (20) underneath the patient's chest, in particular on the side where the patient contacts the ground (G). The apparatus (1) comprises or is connectable to an application aid (30), in functional connection with the band (20), fixable to or movable relative to the band and adapted to support pushing the band (20) underneath the patient's chest. The application aid is stiffer than the band.

Abstract: Systems and methods for cardiopulmonary resuscitation feedback are disclosed. According to an aspect, a method includes determining a force. The method also includes, in response to determining the force, acquiring spatial orientation data, remove the effects of gravity, and wirelessly or wired method of communicating the spatial orientation data.

Abstract: The flow of blood in a vessel (G) in a living being (P) which is exposed to a magnetic field (B) is determined by measuring the potential difference (?V) between at least two points (P1, P2) next to the vessel (G). The potential difference (?V) is produced on the basis of the Hall effect by the moving charge carriers (Q) in the blood in the presence of the magnetic field (B). When recording an ECG, the cardiac output can be determined in this manner under the influence of a magnetic field (B). At the same time, the ECG signal can be corrected in the knowledge of the component (T) of the ECG signal (E) which can be attributed to the Hall effect.

Abstract: To transmit electrophysiological data from an interference region (S) of an MRI arrangement (20) to an evaluation and/or display unit (10) a signal is handled in a recording arrangement (1) arranged within the interference region (S). The ECG signal (E) is first subjected to analogue above-linear compression, is then digitized and is transmitted as a digitized signal (D) to an evaluation and/or display unit (10). The digital signal (D) is subjected to above-linear digital expansion in the evaluation and/or display unit (10).

Abstract: The flow of blood in a vessel (G) in a living being (P) which is exposed to a magnetic field (B) is determined by measuring the potential difference (&Dgr;V) between at least two points (P1, P2) next to the vessel (G). The potential difference (&Dgr;V) is produced on the basis of the Hall effect by the moving charge carriers (Q) in the blood in the presence of the magnetic field (B). When recording an ECG, the cardiac output can be determined in this manner under the influence of a magnetic field (B). At the same time, the ECG signal can be corrected in the knowledge of the component (T) of the ECG signal (E) which can be attributed to the Hall effect.

Abstract: An apparatus for electrotherapy has a checking circuit. The checking circuit is used for checking the functions of the apparatus in a test routine or for requesting the status of components in the apparatus. The apparatus is provided with communication means which interact with the checking circuit and are used for transmitting data, for example the result of a test routine, to a receiver.

Abstract: A device for measuring the resistance of the respiratory tract with the interrupter method consists essentially of a housing (2) which comprises an air passage (3), and of a closing arrangement (5) for temporarily closing the air passage (3). The closing arrangement (5) may be operated via drive means (8). The drive means (8) are arranged and/or designed such that they can be accelerated in a load-free manner from a rest position (R) into an effectual condition (W). In the effectual condition (W) the drive means (8) engages with the closing arrangement and move the latter from a home position (A) into a closing position (V). With this, it is essential that at the point in time of the coming into engagement of the drive means (8) and the closing arrangement (5), the drive means has a certain energy content.
