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.
Claims1
A cardiopulmonary resuscitation (CPR) device to provide active forceful
- decompression of the thorax during circumferential constriction CPR, the CPR
- device comprising:
- a circumferential pneumatic bladder vest adapted to surround the thorax of a patient;
- a pneumatic drive unit configured to provide a forceful inflation of the bladder vest and configured to provide a forceful deflation of the bladder vest.
