1. A system, comprising
a cuirass configured to be coupled to at least a portion of at least one of a thorax or abdomen of a user such that a first internal volume is defined between a surface of the cuirass and at least the portion of the at least one of the thorax or abdomen;
a ventilator coupled to the cuirass so as to be outside of and in fluid communication with the first internal volume, the ventilator comprising:
a housing defining a second internal volume and at least one opening to allow air to flow into or out of the housing;
a pump disposed in the second internal volume, the pump including an inlet and an outlet;
a valve disposed in the second internal volume, the valve defining a first flow path and a second flow path therethrough;
an actuator operatively coupled to the valve; and
a controller in communication with the actuator, the controller configured to:
responsive to determining that the user is exhaling, cause the actuator to move the valve into a first configuration in which the first flow path fluidically couples the outlet to the first internal volume and the second flow path fluidically couples the inlet to second internal volume, and
responsive to determining that the user is inhaling, cause the actuator to move the valve into a second configuration in which the first flow path fluidically couples the inlet to the first internal volume and the second flow path fluidically couples the outlet to the second internal volume,
wherein the housing includes a wall disposed in the second internal volume, the wall separating the second internal volume into a first portion that is fluidically coupled to an external environment through the at least one opening of the housing, and a second portion within which the pump, the valve, and the actuator are disposed, the wall defining a plurality of openings configured to reduce a sound level as air passes between the first portion and the second portion.
