The modular components of the system include a compressor unit, a ventilator which may dock with the compressor unit, and a patient interface which may be connected to either the compressor unit or the ventilator unit. By rearranging these modular components into different configurations, mobility and duration of use may be optimized to fit the present needs. In the stationary configuration, mobility is most restricted, but duration of use is maximized. In the extended range configuration, mobility is enhanced, with duration of use limited by the battery power of the ventilator. In the stand-alone configuration, mobility is maximized, with duration of use limited by battery power of the ventilator and the quantity of an external gas supply. ## Claims ### Claim 1 A ventilatory support apparatus transitionable between a stationary configuration, an extended range configuration, and a stand-alone configuration, the ventilatory support apparatus comprising: a compressor unit, the compressor unit comprising: a compressor for providing compressed gas;
