Claim:
1. An apparatus for assisting a rescuer in performing chest compressions on a patient, the apparatus comprising: a first defibrillation electrode pad or other structure configured to be applied to an anterior location on the thorax of the patient near or at the location at which the rescuer applies force to produce the chest compression, the first pad or other structure comprising a first motion sensor; a second defibrillation electrode pad or other structure configured to be applied to a posterior location on the patient's thorax, the second pad or other structure comprising a second motion sensor; processing circuitry configured to process signals from the first motion sensor and the second motion sensor corresponding to relative motion between the anterior and posterior locations of the thorax to estimate displacement of the chest during resuscitation; and a feedback device connected to the processing circuitry and configured to provide an indication to a rescuer of the estimated displacement of the chest during the performance of chest compressions.
