A subject is mechanically ventilated by a modular ventilator system. The modularity of the system may enable the system to be incorporated into therapy settings with an enhanced convenience comfort and/or form factor. The system may include separate docking stations that are removably coupled with the different modules. This may enable the separate modules to be moved with or without the patient between a plurality of different therapy settings. Gas may be delivered to the subject by the system from one or more gas sources.
