A system applies cardiopulmonary resuscitation (CPR) to a recipient. An automated controller (29) is provided together with a compression device (30 a) which periodically applies a force to a recipient's thorax under control of the automated controller. A band (32) is adapted to be placed around a porti on of the torso of the recipient corresponding to the recipient's thorax. A driver mechanism (34, 40, 42, 44) shortens and lengthens the circumference o f the band. By shortening the circumference of the band, radial forces are created acting on at least lateral and anterior portions of the thorax. A translating mechanism (52) may be provided for translating the radial forces to increase the concentration of anterior radial forces acting on the anteri or portion of the thorax. The driver mechanism may comprise a tension device fo r applying a circumference tensile force to the band. |
