    Abstract: A pneumatic compressor (10) supplies both positive and negative pressure for operating a medical device (300). The pulsing sounds generated by the compressor are attenuated by connecting the inlet (224) of the positive pressure side (34) of the compressor and the outlet (124) of the negative pressure side (32) of the compressor to a common resonating chamber (30). A port (400) in the resonating chamber acts as an outlet for the discharge of excess air in the chamber and an inlet for the entry of make-up air. By adjusting the diameter of the port with respect to the volume of the resonating chamber, sound attenuation can be optimized. In a compact design, the compressor housing serves as the resonating chamber.

    Abstract: 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.
