Abstract
A method of circulating a flow of blood within a circulatory system of a body includes applying an extrathoracic pressure to the body with a fluid. An intrathoracic pressure is applied to the body with the fluid. The application of the extrathoracic pressure relative to the application of the intrathoracic pressure is varied, so as to circulate a flow of blood within the circulatory system of the body.
Claims20
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.
A system for circulating a blood flow within a circulatory system of a body with a surface area, the system comprising:
- a pressurization vessel configured to receive the body and a fluid;
- an extrathoracic pump fluidically coupled to the pressurization vessel and configured to:
- apply a positive extrathoracic pressure across substantially all of the surface area of the body by pressurizing the pressurization vessel;
- and
- apply a negative extrathoracic pressure across substantially all of the surface area of the body with the fluid by depressurizing the pressurization vessel;
- an intrathoracic pump configured to be fluidically coupled to a controlled airway device inserted into the body and configured to:
- apply a positive intrathoracic pressure to the body with the fluid;
- and
- apply a negative intrathoracic pressure to the body with the fluid;
- and
- a fluid treatment circuit fluidically coupled to the extrathoracic pump and the intrathoracic pump.
A system comprising:
- a pressurization vessel comprising a port configured to connect the pressurization vessel to a fluid pump, wherein the pressurization vessel at least partially defines a receiver for receiving a body with an extrathoracic surface area and an intrathoracic lung volume;
- a sensor for detecting a condition within the body when the body is received within the receiver, and
- a controller configured to be communicatively coupled to the sensor, wherein the controller comprises at least one auxiliary input for connecting the controller to the fluid pump and wherein the controller is configured to control the fluid pump to:
- pressurize the pressurization vessel to apply a positive extrathoracic pressure across substantially all of the extrathoracic surface area of the body;
- depressurize the pressurization vessel to apply a negative extrathoracic pressure across substantially all of the extrathoracic surface area of the body;
- apply a positive intrathoracic pressure to the intrathoracic lung volume with the fluid;
- apply a negative intrathoracic pressure to the intrathoracic lung volume with the fluid;
- and
- vary, based on communications with the sensor, 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 a circulatory system of the body.
