Methods, systems and devices are described for new modes of ventilation in which specific lung areas are ventilated with an indwelling trans-tracheobronchial catheter for the purpose of improving ventilation and reducing hyperinflation in that specific lung area, and for redirecting inspired air to other healthier lung areas. Trans-tracheobronchial Segmental Ventilation (TTSV) is performed on either a naturally breathing or a mechanical ventilated, patient by placing a uniquely configured indwelling catheter into a bronchus of a poorly ventilated specific lung area and providing direct ventilation to that area. Typically the catheter's distal tip is anchored without occluding the bronchus. TTSV is optionally performed by insufflation only of the area, or by the application of vacuum to the area, can include elevating or reducing the pressure in the targeted area to facilitate stagnant gas removal, or can include blocking the area to divert inspired gas to better functioning areas.

Systems and methods may include a nasal interface apparatus for receiving ventilation gas from gas delivery tubing and for humidifying ventilation gas. The nasal interface apparatus may have one or more channels within the nasal interface to deliver gas from a gas delivery circuit to a patient's nose; one or more structures in fluid communication with the one or more channels to direct ventilation gas to the patient's nose; and a hygroscopic material within the nasal interface in the flow path of the ventilation gas.

A portable liquid oxygen system may provide an average flow rate of oxygen gas at approximately 6-approximately 20 lpm using a rapid gas conversion mode. The rapid gas conversion mode utilizes a Stirling engine that harnesses the heat differential between the ambient temperature and the liquid oxygen store to drive a fan. The fan operates to blow ambient air across a heat exchanger, which allows the heat exchanger to more rapidly evaporate liquid oxygen into oxygen gas.
