    • An active compression/decompression CPR device capable of providing both complete cardiopulmonary support and cardiopulmonary assistance includes two or more thoracic compressors, preferably inflatable bladders, positioned so that the chest can first be flattened and compressed, increasing the pressure in the chest, and then circularized and decompressed, decreasing the pressure in the chest. When inflatable bladders are used, they can be surrounded with a rigidifying vest which resists outward bladder expansion. Compression and decompression can be performed along with abdominal compression, and the device is capable of shifting between support and assist modes when the patient's condition so requires. Also described is a method of compressing and then decompressing a patient's thorax by applying anterior and/or posterior pressure to the thorax, so as to compress the thorax and increase pressure therein, relieving that pressure, and then applying lateral pressure to the thorax to decompress and relieve pressure in the thorax, and then relieving the lateral pressure.
    • 能够提供完整的心肺支持和心肺辅助的主动的压缩/减压CPR装置包括两个或更多个胸部压缩机,优选是可充气的囊,其被定位成使得胸部可以首先被压平和压缩,增加胸部的压力, 并减压,减轻胸部压力。 当使用充气气囊时,它们可以用抵抗膀胱膨胀的刚性背心围起来。 压缩和减压可以与腹部压缩一起进行,并且当患者的状况如此需要时,该装置能够在支撑和辅助模式之间移动。 还描述了通过对胸部施加前和/或后压力来压缩并随后对患者胸部进行解压缩的方法,以便压缩胸部并增加其中的压力,缓解该压力,然后向胸部施加横向压力以减压 缓解胸部压力,缓解压力。
