Abstract: An automated ventilation, CPR and circulatory assistance apparatus includes an airway apparatus 10, a vest 12 including an inflatable bladder 18, and an abdominal restraint 14 including an inflatable bladder 22. An airway pneumatic control apparatus 84, a vest pneumatic control apparatus 86, and an abdominal restraint pneumatic control apparatus 88 are in fluid communication with the airway apparatus, the vest bladder, and the abdominal restraint bladder, respectively, and responsive to respective first and second states in an airway control signal AWC, a vest control signal VC, and an abdominal restraint control signal ARC to alternately inflate and deflate the patient's lungs, the vest bladder, and the abdominal restraint bladder, respectively. Provision is made for selectively adjusting the volume of gas that is coupled to the patient's lungs, and the maximum pressures that are obtained in the vest bladder and the abdominal restraint bladder.
