1. An apparatus that monitors cardio pulmonary resuscitation (CPR), the apparatus comprising:
a sensor that senses an impedance signal associated with chest recoil of a person when CPR is administered to the person;
a controller that:
receives the impedance signal sensed by the sensor;
identifies an amplitude of the impedance signal associated with the chest recoil of the person,
compares the impedance signal amplitude with impedance baseline data, and
identifies that a message should be provided to a rescuer based on the comparison of the impedance signal amplitude with the impedance baseline data; and
a user interface that provides the message to the rescuer.
