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.

The detachable battery pack of claim 6, wherein the at least one fastening mechanism further comprises a release mechanism disposed on the second side of the enclosure of the detachable battery pack, and wherein at least one of the first protrusion and the second protrusion is movably coupled to the release mechanism, in order that movement of the release mechanism results in a corresponding movement of the at least one of the first protrusion and the second protrusion, thereby disengaging the detachable battery pack from the housing of the ventilator. 8. The detachable battery pack of claim 1, wherein, when the enclosure is disposed in the predetermined orientation within the cavity, the second side of the enclosure is structured to be substantially flush with respect to the exterior surface of the housing adjacent the cavity. 9. The detachable battery pack of claim 1, wherein the enclosure further include a charge indicator structured to indicate the measured capacity of the number of batteries. 10. The detachable battery pack of claim 9, wherein the charge indicator comprises a plurality of LEDs electrically connected to the number of batteries, and wherein the number of batteries illuminate a number of the LEDs corresponding to the measured capacity of the number of batteries of the detachable battery pack. 11. The detachable battery pack of claim 1, wherein the ventilator further includes an electrical connector disposed within the cavity of the housing, wherein the electrical connector of the detachable battery pack is disposed on the first side of the enclosure of the detachable battery pack, and wherein, when the detachable battery pack is inserted into the cavity in the predetermined orientation, the electrical connector of the detachable battery pack is structured to align with and electrically connect to the electrical connector of the ventilator. 12. The detachable battery pack of claim 1, wherein surfaces of the first end, the second end, the first side, a left side, and a right side of the enclosure are substantially concealed by the cavity, and a surface of the second side is exposed. 13.
