The purpose of the present invention is to provide a cardiopulmonary resuscitation system capable of avoiding fighting in an asynchronous mode in which chest compression and artificial respiration are performed independently and continuously. This cardiopulmonary resuscitation system (100) comprises: a chest compression means (120) having an impact hammer (121) that compresses the chest of a patient, said chest compression means repeating a chest compression cycle having, as one cycle, a compression period in which the impact hammer hits the chest and a recoil period in which the impact hammer moves away from the chest； an artificial respiration means (110) that repeats an artificial respiration cycle having, as one cycle, an inhalation period in which breathing gas is supplied to the patient and an exhalation period in which supply of the breathing gas is stopped； and a control means that controls the artificial respiration means and the chest compression means. The control means executes the chest compression cycle a prescribed number of times per unit time, executes the artificial respiration cycle a prescribed number of times per unit time, and stops the impact hammer from hitting the chest during compression periods that overlap inhalation periods.La présente invention vise à proposer un système de réanimation cardiopulmonaire apte à éviter un combat dans un mode asynchrone dans lequel une compression de poitrine et une respiration artificielle sont réalisées indépendamment et de manière continue. Le système de réanimation cardiopulmonaire (100) de la présente invention comprend : un moyen de compression de poitrine (120) présentant un marteau à percussion (121) qui comprime la poitrine d'un patient, ledit moyen de compression de poitrine répétant un cycle de compression de poitrine présentant, en tant qu'un seul cycle, une période de compression pendant laquelle le marteau à percussion frappe la poitrine et une période de recul pendant laquelle le marteau à pe
