Abstract: 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.

Abstract: A Cardio-Pulmonary Resuscitation (“CPR”) device can include a compression mechanism configured to perform successive CPR compressions on a chest of a patient, the compression mechanism including a piston and a contact member attached to the piston, the contact member configured to make and maintain contact with the chest at a first position and a first orientation. The CPR device can also include a controller communicatively coupled with the compression mechanism, the controller configured to: receive at least one input; determine whether the piston should be adjusted based on the at least one input; and responsive to a determination that the piston should be adjusted, cause the piston to move so that the contact member makes and maintains contact with the chest at a second position and a second orientation.
