1. A ventilator system for providing therapy to a patient, comprising:
a housing;
a ventilation assembly in the housing and configured to provide a breath composed at least partially of inspiratory gas, the ventilation assembly including a ventilation port in the housing for providing the inspiratory gas to a patient circuit;
an oxygen assembly in the housing and having an oxygen source configured to provide oxygen, the oxygen assembly further including an oxygen port in the housing for delivering the oxygen to an oxygen delivery circuit;
a sensor configured to measure a pressure level for triggering delivery of the breath and/or the oxygen; and
an adapter configured to interface with the oxygen port, the oxygen delivery circuit, and the sensor, wherein the adapter is further configured to (i) transmit at least a portion of a reduction in pressure induced in the oxygen delivery circuit during a patient's initial inspiratory effort to the sensor for triggering the delivery of the oxygen and/or the breath, and (ii) route the oxygen from the oxygen outlet port to the oxygen delivery circuit,
wherein the system is transitionable between (a) a ventilation mode in which the ventilation assembly provides inspiratory gas to the patient circuit, (b) an oxygen mode in which the oxygen assembly provides oxygen to the oxygen delivery circuit, and (c) a combination mode in which the ventilation assembly provides inspiratory gas to the patient circuit and the oxygen assembly provides oxygen to the oxygen delivery circuit.
