1. A Cardio-Pulmonary Resuscitation (CPR) system, the CPR system comprising:
a compression mechanism attached to a retention structure, the compression mechanism configured to perform CPR compressions to a chest of a patient alternating with releases of the CPR compressions;
a controller configured to:
control the compression mechanism to perform a first group of the CPR compressions,
stop performing lasting a predetermined amount of time during a first check pause,
at the end of the first check pause, control the compression mechanism to perform a second group of the CPR compressions, and
determine whether a check patient condition has been met based at least on a determination of whether a threshold number of the CPR compressions have been performed in the second group of the CPR compressions and whether a pause instruction has been received from another device, the check patient condition being met when either or both of the threshold number of the CPR compressions being performed and the pause instruction being received from the other device are satisfied, and
when the check patient condition is met, stop performing the second group of the CPR compressions for a second check pause lasting the predetermined amount of time; and
a user interface configured to output a human-perceptible check patient prompt responsive when the check patient condition is met, the check patient prompt reminding a rescuer to check the patient for a non-ventilation condition.
