In embodiments, a CPR chest compression system includes a retention structure that can retain the patient's body, and a compression mechanism that can perform automatically CPR compressions and releases to the patient's chest. The compression mechanism can pause the performing of the CPR compressions for a short time, so that an attendant can check the patient. The CPR system also includes a user interface that can output a human-perceptible check patient prompt, to alert an attendant to check the patient during the pause. An advantage can be when the attendant checks in situations where the condition of the patient might have changed, and an adjustment is needed. Or in situations where the patient may have improved enough to where the compressions are no longer needed.

CPR chest compression system with motor powered by battery located away from the motor
A CPR chest compression system includes a retention structure that retains the body of a patient, and a motor and a compressor that can perform CPR compressions to the chest of the patient. The motor is powered by a battery that is located on the retention structure but away from the motor, and is electrically connected to the motor via one or more wires. Accordingly the weight and volume of the battery can be located away from a top portion of the retention structure. This renders the CPR system is less heavy at the top, and therefore less likely to tilt and start compressing the chest at a different point. Moreover, this permits X-Rays of a larger footprint to go through the CPR system and reach the patient, in example configurations where the components are transparent to X-Rays.

In embodiments, a Cardio-Pulmonary Resuscitation (CPR) system includes a retention structure, a compression mechanism coupled to the retention structure and a backboard. The retention structure and the backboard can be assembled together so as to form a closed loop that surrounds the patient's torso, and a piston of the compression mechanism is movable towards and away from a chest of a patient. In addition, the CPR system has a stabilizing member, and a coupler configured to couple the stabilizing member to the backboard. The stabilizing member can prevent the retention structure from tilting while the CPR system delivers chest compressions to the patient.

The disclosed CPR devices, systems, and methods adjust a compression depth of a compression mechanism to account for chest collapse of the patient receiving CPR. Compression depth can be adjusted up to a maximum depth in some examples. The compression depth can also be adjusted linearly or non-linearly as the zero point or starting position of the patient's chest changes due to chest collapse. Other factors can also be used to adjust the compression depth such as patient parameters that can be observed by a rescuer or sensed by sensors wirelessly connected to or integrated into the system. CPR devices that include active decompression can also use the disclosed techniques for adjusting the chest compression depth as the patient's chest collapses.

A back plate for use with a CPR compression device can include first and second static attachment elements configured on first and second sides, respectively, to releasably connect to first and second legs, respectively. In addition, a bottom surface of the back plate can include a plurality of ribs that run from the first side to the second side in parallel to the third and fourth sides. The back plate also includes a hollow portion between the upper and bottom surfaces and the first, second, third, and fourth sides, and the ribs and third and fourth sides provide structural rigidity to the back plate. A plurality of openings along the third and fourth sides may be configured for strapping the back plate to a patient. Grooves may be configured on the top surface to hide sink marks on the top surface caused by the ribs on the bottom surface.
A CPR chest compression system (200, 500, 600, 1100) includes a retention structure (240, 1140) that retains the body of a patient (282), and a motor (249, 1149, 1249, 1349) and a compression mechanism (248, 1148) that can perform CPR compressions to the chest of the patient. The motor is powered by a battery (261, 561, 562, 661, 662, 1161) that is located on the retention structure but away from the motor, and is electrically connected to the motor via one or more wires (246, 1146, 1246, 1346). Accordingly the weight and volume of the battery can be located away from a top portion of the retention structure. This renders the CPR system is less heavy at the top, and therefore less likely to tilt and start compressing the chest at a different point. Moreover, this permits X-Rays of a larger footprint to go through the CPR system and reach the patient, in embodiments where other components of the CPR system are transparent to X-Rays.

A CPR system includes a retention structure to retain the patient's body, and a compression mechanism to perform CPR compressions to the patient's chest. The CPR system further includes a processor to control the compression mechanism, and thus the performance of the CPR compressions. In embodiments, the CPR system compresses at a rate or frequency that is purposely sub-optimal for circulation at least some of the time, and especially when it is detected that the patient has regained consciousness. An advantage can be that the patient may thus faint again, and therefore perceive less of the unpleasant experience of the mechanical chest compressions that the CPR system continues to perform on them as it preserves them alive.
