PROBLEM TO BE SOLVED: To provide a cardiopulmonary resuscitation system capable of performing a passive oxygen administration reducing an oxygen consumption compared with that of the conventional passive oxygen administration method.SOLUTION: A cardiopulmonary resuscitation system 100 according to the present invention includes: sternal bone oppression means 120 repeating a sternal bone oppression cycle with an oppression period and a recoil period defined as one cycle； artificial respiration means 110 for repeating an artificial respiration cycle with an inhalation period and an exhalation period defined as one cycle and capable of supplying an oxygen administration gas to a patient during the recoil period； and control means (not shown) for controlling the artificial respiration means 110 and/or the sternal bone oppression means 120. The control means determines necessity/unnecessity of the supply of the oxygen administration gas for each recoil period and, in a case other than the unnecessity determination, transmits a supply instruction signal for administering the oxygen administration gas, to the artificial respiration means.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】本開示は、従来の受動的酸素投与法と比較して酸素消費量を低減した受動的酸素投与を行うことができる心肺蘇生システムを提供することを目的とする。【解決手段】本発明に係る心肺蘇生システム１００は、圧迫期間とリコイル期間とを１サイクルとする胸骨圧迫サイクルを繰り返す胸骨圧迫手段１２０と、吸気期間と呼気期間とを１サイクルとする人工呼吸サイクルを繰り返すとともに、リコイル期間中に患者に酸素投与用ガスを供給可能な人工呼吸手段１１０と、人工呼吸手段１１０及び／又は胸骨圧迫手段１２０を制御する制御手段（不図示）と、を備え、制御手段は、リコイル期間毎に酸素投与用ガスの供給の要否を判断し、否の判断以外では酸素投与用ガスを投与する供給指示信号を人工呼吸手段に対して送る。【選択図】図１
