Abstract
The present invention is a method for improving hemodynamics and clinical outcome of patients suffering cardiac arrest and other low-flow states by combination of circumferential constriction and anteroposterior compression decompression of the chest cardiopulmonary resuscitation. Anteroposterior compression decompression may be provided by a piston mechanism attached to a gantry above the patient. Circumferential constriction may be achieved by inflation of pneumatic bladders or shortening of a band. The on-off sequence and relative force of circumferential constriction and anteroposterior compression decompression may be adjusted so as to improve efficacy.
