A ventilator that is small, lightweight, and portable, yet capable of being quickly adapted to operate in a plurality of different modes and configurations to deliver a variety of therapies to a patent. A porting system having a plurality of sensors structured to monitor a number of parameters with respect to the flow of gas, and a number of porting blocks is used to reconfigure the ventilator so that it operates as a single-limb or dual limb ventilator. In the single-limb configuration, an active or passive exhaust assembly can be provided proximate to the patient. The ventilator is capable of operate in a volume or pressure support mode, even in a single-limb configuration. In addition, a power control mechanism controls the supply of power to the ventilator from an AC power source, a lead acid battery, an internal rechargeable battery pack, and a detachable battery pack.

1. A ventilator comprising: (a) a housing having an interior and an exterior;(b) an inlet port extending from the exterior to the interior of the housing;(c) a flow generator disposed within the ventilator and being structured to generate a flow of gas;(c) an outlet port for discharging the flow of gas from the housing; and(d) an inlet airflow assembly comprising: (1) a cover member selectively coupled to the housing of the ventilator at or about the inlet port, the cover member comprising a first side, a second side disposed opposite the first side, a plurality of walls extending substantially perpendicularly outwardly from the first side of the cover member, and an inlet aperture extending through the cover member, and(2) a number of filtering members disposed between the first side of the cover member and the housing of the ventilator, wherein at least one of the walls extends through a corresponding one of the filtering members. 2. A method of servicing a ventilator, the ventilator comprising a housing, an inlet port, a flow generator, an outlet port, and an inlet airflow assembly, the method comprising: (a) providing the inlet airflow assembly with a cover member and a number of filtering members, the cover member being selectively coupled to the housing of the ventilator at or about the inlet port and comprising a first side, a second side disposed opposite the first side, a plurality of walls extending substantially perpendicularly outwardly from the first side of the cover member, and an inlet aperture extending through the cover member, the inlet aperture being structured to deliver a gas to the inlet port of the ventilator, the number of filtering members being disposed between the first side of the cover member and the housing of the ventilator, wherein at least one of the walls extends through a corresponding one of the filtering members;(b) removing the inlet airflow assembly from the housing of the ventilator, without requiring the disassembly of the remainder of the ventilator; and(c) performing at least one of the following servicing steps: (1) cleansing the cover member,(2) replacing the number of filtering members with a number of new filtering members, and(3) attaching a new inlet airflow assembly to the housing of the ventilator. 3. An inlet airflow assembly for a ventilator, the ventilator including a housing having an exterior surface and a pocket extending inwardly from the exterior surface, an inlet port, a flow generator structured to generate a flow of gas, and an outlet port structured to discharge the flow of gas from the housing, the inlet airflow assembly comprising: a cover member structured to be selectively coupled to the housing of the ventilator at or about the inlet port, the cover member comprising a first side, a second side disposed opposite the first side, a plurality of walls extending substantially perpendicularly outwardly from the first side of the cover member, and an inlet aperture extending through the cover member, the inlet aperture being structured to deliver a gas to the inlet port of the ventilator;a number of filtering members disposed between the first side of the cover member and the housing of the ventilator, wherein at least one of the walls extends through a corresponding one of the filtering members; anda fastening mechanism structured to fasten the cover member to the housing of the ventilator, thereby securing the cover member and the number of filtering members with respect to the housing, wherein the inlet airflow assembly is removable from the housing, without requiring the remainder of the ventilator to be disassembled. 4. The inlet airflow assembly of claim 3, wherein the cover member is structured to be disposed within the pocket, and wherein, when the cover member is disposed within the pocket, the second side of the cover member is substantially flush with respect to the exterior surface of the housing of the ventilator adjacent the pocket. 5. The inlet airflow assembly of claim 4, wherein the walls of the cover member form an inlet airflow path, and wherein the inlet airflow path is structured to extend from the inlet aperture of the cover member toward the inlet port of the ventilator. 6. The inlet airflow assembly of claim 5, wherein the cover member includes four peripheral edges, wherein the walls of the cover member include an outer wall disposed proximate the four peripheral edges, and an inner wall spaced inwardly from the outer wall, wherein the inner wall is structured to extend around at least a portion of the inlet port of the ventilator, and wherein the inlet airflow path is disposed between the outer wall and the inner wall. 7. The inlet airflow assembly of claim 6, wherein the cover member further comprises a duct extending inwardly from the first side of the cover member at or about the inlet aperture, and wherein the duct is structured to direct the gas into the inlet airflow path. 8. The inlet airflow assembly of 5, wherein the number of filtering members includes at least one air filter, and wherein the at least one air filter is disposed between the walls in the inlet airflow path in order that the gas flows through the at least one air filter. 9. The inlet airflow assembly of claim 8, at least one air filter includes a plurality of slots extending therethrough, wherein at least some of the walls of the cover member extend through the slots in order to maintain the position of the at least one air filter with respect to the cover member, and wherein the at least one air filter is selectively detachable from the cover member. 10. The inlet airflow assembly of claim 3, wherein the number of filtering members comprises a first filtering member and a second filtering member, wherein the first filtering member is structured to be disposed adjacent the housing of the ventilator, and wherein the second filtering member is disposed between the first filtering member and the first side of the cover member. 11. The inlet airflow assembly of claim 10, wherein the first filtering member has a first thickness, wherein the second filtering member has a second thickness, and wherein the second thickness of the second filtering member is greater than the first thickness of the first filtering member. 12. The inlet airflow assembly of claim 10, wherein the first filtering member includes a hole structured to align with the inlet port of the ventilator, and wherein the first filtering member is structured to overlay the first side of the cover member.
