A ventilatory support apparatus transitionable between a stationary configuration and an extended range configuration, the ventilatory support apparatus comprising: a compressor unit, the compressor unit comprising: a compressor for providing compressed gas; a ventilator dock having a ventilator dock compressed gas output port and a ventilator dock ventilation gas inlet port; a compressor unit ventilation gas output port; and a compressor unit compressed gas output port; a ventilator for providing ventilation gas, the ventilator being configured for removable docking at the ventilator dock, the ventilator comprising: a ventilator ventilation gas output port; and a ventilator compressed gas inlet port; and a patient interface for receiving ventilation gas and delivering ventilation gas to a patient, the patient interface having a patient interface gas inlet port transitionable between placement in fluid communication with the compressor unit ventilation gas output port and placement in fluid communication with the ventilator ventilation gas output port; wherein, when the ventilatory support apparatus is transitioned to the stationary configuration, the ventilator is docked at the ventilator dock, the ventilator compressed gas inlet port is in fluid communication with the ventilator dock compressed gas output port, the ventilator ventilation gas output port is in fluid communication with the ventilator dock ventilation gas inlet port, and the patient interface gas inlet port is in fluid communication with the compressor ventilation gas output port, such that, in use, compressed gas is provided by the compressor unit to the ventilator and ventilation gas is returned to the compressor unit for subsequent output from the compressor unit to the patient interface; and wherein, when the ventilatory support apparatus is transitioned to the extended range configuration, the ventilator is not docked at the ventilator dock, the ventilator compressed gas inlet port is in fluid communication with the compressor unit compressed gas output port via a compressed gas hose, and the patient interface gas inlet port is in fluid communication with the ventilator ventilation gas output port, such that, in use, compressed gas is provided by the compressor unit to the ventilator and ventilation gas is provided by the ventilator to the patient interface without being returned to the compressor unit. a compressor unit, the compressor unit comprising: a compressor for providing compressed gas;
