1. A Cardio-Pulmonary Resuscitation (“CPR”) machine configured to perform chest compressions on a chest of a patient, the chest having a resting height relative to a reference level, the resting height measured when no chest compressions are being performed, the CPR machine comprising:
a compression mechanism;
a chest-lifting device configured to lift the chest; and
a driver system configured to drive the compression mechanism and the chest-lifting device according to a motion-time profile so as to cause the chest-lifting device to lift the chest a first distance from the resting height and the chest-lifting device to lift the chest a second distance from the resting height greater than the first distance after lifting the chest to the first distance.

11. A method for a Cardio-Pulmonary Resuscitation (“CPR”) machine to perform chest compressions on a chest of a patient, the chest having a resting height relative to a reference level, the resting height measured when no chest compressions are being performed on the patient, the method comprising:
driving a chest-lifting device to lift the chest to a first distance from the resting height;
driving the chest-lifting device to lift the chest to a second distance from the resting height, after lifting the chest the first distance, the second distance greater than the first distance; and
driving a compression mechanism to perform one or more compressions on the chest.
