OG exemplary drawing
 
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, the driver system further configured to drive only the compression mechanism for a chest-lift delay period and drive the chest-lifting device when the chest-lift delay period has elapsed, wherein the driver system is further configured to lift the chest to a second distance after lifting the chest to the first distance and cause the compression mechanism to not resume performance of compressions until after the chest-lifting device lifts the chest the second distance.
 
6. 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 compression mechanism to perform one or more compressions on the chest for a first time period and a second time period; and
driving a chest-lifting device to lift the chest to a first distance from the resting height after the first time period has elapsed and lifting the chest to a second distance after lifting the chest to the first distance, wherein the compression mechanism is driven to resume performance of chest compressions only after the chest-lifting device lifts the chest the second distance.
 
11. 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, the motion-time profile comprising a first time period and a second time period, and wherein the driver system is further configured to lift the chest to a second distance after lifting the chest to the first distance and cause the compression mechanism to perform compressions in the second period only after the chest-lifting device lifts the chest to the second distance.
