PROBLEM TO BE SOLVED: To provide a cardiac massage support device capable of being easily used in a lifesaving practice, and allowing execution of a treatment without giving a uncomfortable feeling in the actual cardiac massage at a lifesaving site.SOLUTION: A cardiac massage support device 1 for supporting a proper treatment for cardiac massage includes: a video camera 4 provided in a position detector 5 fixed to a hand of a cardiac massage treating person P2 and capturing images of at least three markers; and a main device 2 connected to the video camera 4 and displaying movement of a measuring point representing a position of the position detector 5 based on the change of positions of the respective markers captured by the video camera 4. The cardiac massage support device 1 at least includes a measuring point determining means for determining the position of the measuring point, a measuring point tracing means for tracing the change of position of the measuring point, and a display processing means for displaying the change of position of the measuring point on a monitor. This invention also provides a cardiac massage supporting computer program which is readable and executable in the device 1.【課題】手軽に救命訓練に利用でき、また、救命の現場でも実際の心臓マッサージと違和感のない措置を実行できる心臓マッサージ支援装置を提供する。【解決手段】心臓マッサージの正しい処置を支援するための心臓マッサージ支援装置1であって、心臓マッサージの施術者P2の手に固定される位置検出器5に備える少なくとも3つのマーカを撮像するビデオカメラ4と、ビデオカメラ4と接続されると共に、ビデオカメラ4によって撮像されるそれぞれのマーカの各位置の変化に基づき位置検出器5の位置を代表する測定点の移動を表示する本体機器2とを備え、測定点の位置を決定する測定点決定手段と、測定点の位置の変化を追跡する測定点追跡手段と、測定点の位置の変化をモニタに表示させる表示処理手段とを少なくとも備える心臓マッサージ支援装置1および当該装置1に読み取りかつ実行可能な心臓マッサージ支援用コンピュータプログラム。【選択図】図1
