1. A method of circulating a flow of blood within a circulatory system of a body with a surface area, the method comprising:
applying a positive extrathoracic pressure across substantially all of the surface area of the body with a fluid within a pressurization vessel;
applying a positive intrathoracic pressure to the body with the fluid;
applying a negative extrathoracic pressure across substantially all of the surface area of the body with the fluid by depressurizing the pressurization vessel;
applying a negative intrathoracic pressure to the body with the fluid; and
varying the application of the positive extrathoracic pressure relative to the application of the positive intrathoracic pressure and the application of the negative extrathoracic pressure relative to the application of the negative intrathoracic pressure, so as to circulate the blood flow within the circulatory system of the body.
