Systems and methods are provided for humidifying ventilation gas. 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.
1. A system for humidifying ventilation gas, the system comprising: a ventilator;a patient circuit in fluid communication with the ventilator at a proximal end and adapted to be fluidly connected to a patient airway at a distal end, wherein the patient circuit has an inner diameter of approximately
1.

The system of claim 1, further comprising a patient interface, wherein the patient interface is a nasal interface, an oral interface, or a trans-tracheal interface. 3. The system of claim 1, wherein the fluid is water, a drug solution, or combinations thereof. 4. The system of claim 1, wherein a drug is delivered alternatively with humidification. 5. The system of claim 1, wherein the ventilator is portable. 6. The system of claim 1, wherein the fluid reservoir is pressurized by gas from the ventilator. 7. The system of claim 1, wherein the gas channel is adapted to deliver gas to create a jet prior to the misting screen. 8. The system of claim 1, further comprising a hydrophilic media cartridge in fluid communication with the patient circuit. 9. The system of claim 1, further comprising a capillary force vaporizer. 10. The system of claim 1, further comprising a vibrating mesh nebulizer. 11. The system of claim 1, wherein the gas channel surrounds the fluid channel. 12. The system of claim 1, wherein the fluid channel surrounds the gas channel. 13. The system of claim 1, further comprising a vortex heat separator for providing hot gas to the humidification device and cold gas to the ventilator. 14. The system of claim 1, wherein delivery of the humidified ventilation gas is servo controlled. 15. The system of claim 1, wherein the humidified ventilation gas is delivered in synchrony with the patient's breathing cycle. 16. The system of claim 1, wherein an average flow rate of gas delivered by the ventilator is greater than approximately 6 lpm. 17. The system of claim 1, wherein the delivery of humidified gas is controlled to within 50 to 95% relative humidity to prevent rainout within the patient circuit. 18. The system of claim 1, wherein the patient circuit further includes a wall disposed between the gas delivery channel and the fluid delivery channel, wherein a distal end portion of the fluid delivery channel extends distally beyond a distal end of the wall and merges into the gas delivery channel. 19. The system of claim 1, wherein the misting screen is in axial alignment with a longitudinal axis of the gas channel. 20. The system of claim 1, wherein a distal end portion of the fluid delivery channel merges into the gas delivery channel. 21. A method of treating respiratory and breathing disorders, the method comprising: providing a ventilation system comprising: a ventilator;a fluid reservoir;a humidification device; anda patient circuit in fluid communication with the ventilator at a proximal end and fluidly connected to a patient airway at a distal end, the patient circuit including: a ventilation gas delivery channel fluidly connected to the ventilator; a gas channel;a fluid channel fluidly connected to the humidification device; and a misting screen in axial alignment with a longitudinal axis of the gas channel; andusing the ventilation system to deliver ventilation gas through the patient circuit to a patient. 22. The method of claim 21, further comprising controlling delivery of the humidified ventilation gas with a servo. 23. The method of claim 21, further comprising delivering the humidified ventilation gas in synchrony with the patient's breathing cycle. 24. The method of claim 21, further comprising delivering a drug solution alternatively with the humidified ventilation gas. 25. The method of claim 21, wherein an average flow rate of gas delivered by the ventilator is greater than approximately 6 lpm. 26. The method of claim 21, wherein the patient circuit further includes a wall disposed between the gas delivery channel and the fluid delivery channel, wherein a distal end portion of the fluid delivery channel extends distally beyond a distal end of the wall and merges into the gas delivery channel. 27. A system for humidifying ventilation gas, the system comprising: a ventilator;a patient circuit in fluid communication with the ventilator at a proximal end and adapted to be fluidly connected to a patient airway at a distal end, wherein the patient circuit has an inner diameter of approximately 2-14 mm;a fluid reservoir;a humidification device;a channel between the humidification device and a distal end of the patient circuit; anda vortex heat separator for providing hot gas to the humidification device and cold gas to the ventilator.
