A chest compression device for cardiopulmonary resuscitation comprises a support structure 2 for placement about a patient's chest and for holding a chest compressor 6 above a patient's sternum; a chest compressor 6 mounted on the support structure 2; and lateral chest supports 14 attached to the support structure 2 at points laterally either side of the chest when the device is in use, such that the lateral chest supports 14 will apply lateral pressure to the sides of the chest synchronized with a chest compression by the chest compressor 6.

An automated chest compression device for performing CPR, with distance sensors disposed on a compressing mechanism and on a structure fixed relative to the CPR patient, for determining inferior/superior movement of the compressing mechanism over the course of multiple compressions.

A chest compression device for cardiopulmonary resuscitation may include a support structure for placement about a patient's chest and for holding a chest compressor above a patient's sternum; a chest compressor mounted on the support structure; and lateral chest supports attached to the support structure at points laterally on either side of the chest when the device is in use, such that the lateral chest supports will apply lateral pressure to the sides of the chest synchronised with a chest compression by the chest compressor.

A system for assisting with a cardiopulmonary resuscitation (CPR) treatment being administered to a patient. In one aspect, the system includes electrodes to provide an ECG signal of the patient, one or more sensors configured to measure an intrinsic myocardial wall movement of the patient, and one or more processors. The one or more processors are configured to perform operations including: during the CPR treatment being administered to the patient, receiving an input from the sensor(s), processing the input from the sensor(s) and the ECG signal, determining, based on processing, whether the intrinsic myocardial wall movement is indicative of a perfusion movement of the patient's heart, and providing an indication to a user of the system based on the determination.

A system applies cardiopulmonary resuscitation (CPR) to a recipient. An automated controller is provided together with a compression device which periodically applies a force to a recipient's thorax under control of the automated controller. A band is adapted to be placed around a portion of the torso of the recipient corresponding to the recipient's thorax. A driver mechanism shortens and lengthens the circumference of the band. By shortening the circumference of the band, radial forces are created acting on at least lateral and anterior portions of the thorax. A translating mechanism may be. provided for translating the radial forces to increase the concentration of anterior radial forces acting on the anterior portion of the thorax. The driver mechanism may comprise a tension device for applying a circumference tensile force to the band. The driver mechanism may comprise an electric motor, a pneumatic linear actuator, or a contracting mechanism defining certain portions of the circumference of the band. The contracting mechanism may comprise plural fluid-receiving cells linked together along the circumference of the band. The width of each of the fluid-receiving cells becomes smaller as each cell is filled with a fluid. This causes the contraction of the band and a resulting shortening of the circumference of the band.

Devices and methods for CPR chest compression with active decompression.

An elevation device used in the performance of cardiopulmonary resuscitation (CPR) and after resuscitation includes a base and an upper support operably coupled to the base. The upper support is configured to incline at an angle relative to the base to elevate an individual's upper back, shoulders and head. The elevation device includes a support arm coupled with the upper support. The support arm is movable to various positions relative to the upper support and is lockable at a fixed angle relative to the upper support such that the upper support and the support arm are movable as a single unit relative to the base while the support arm maintains the angle relative to the upper support. The elevation device also includes a chest compression device coupled with the support arm. The chest compression device is configured to compress the chest.

A CPR machine (100) is configured to perform, on a patient's (182) chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A force sensing system (149) may sense a compression force, and the driving can be adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (850). An optional chest-lifting device (152) may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected.
