Abstract: Hybrid ventilation apparatuses, systems and methods are provided. Some example mechanical ventilation apparatuses include a gas delivery system, at least one oxygen concentrator for generating oxygen enriched gas for delivery to a patient, at least one pressurized oxygen source for providing oxygen for delivery to the patient, and a controller. Based at least in part on an FIO2 setting for the gas to be delivered to the patient, the controller may determine an oxygen enriched gas flow rate of the oxygen enriched gas and a pressurized oxygen source flow rate of the oxygen from the at least one pressurized oxygen source, for the gas to be delivered to the patient. The controller may control the gas delivery system to deliver the gas to the patient in accordance with the FIO2 setting, the determined oxygen enriched gas flow rate, and the determined pressurized oxygen source flow rate.
