A CPR machine () is configured to perform, on a patient's () chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (), and a driver system () configured to drive the compression mechanism. A force sensing system () 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 (). An optional chest-lifting device () 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.

An optional chest-lifting device () 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. An advantage is that a changing condition in the patient or in the retention of the patient within the CPR machine may be detected and responded to.

Defibrillators, software and methods are provided, for transmitting inaudible audio information to one or more external personal sound devices. The audio information may encode an audible indication, which can thus be played by an external personal sound device to a user such as a rescuer.
