A ventilation apparatus for treating sleep apnea is provided. A ventilator controlled by a control system may deliver ventilation gas through a ventilation gas delivery circuit to a ventilation catheter and a distal tip on the ventilation catheter. One or more sensors may detect a breathing cycle and the control system may operate the ventilator in synchrony with the breathing cycle. The distal tip may deliver the ventilation gas superiorly from the transtracheal ventilation catheter towards an upper airway, inferiorly from the transtracheal ventilation catheter towards a lung, or a combination of both. The ventilation catheter may be a transtracheal catheter, a trans-oral catheter or a trans-nasal catheter.

A method for cerebral and systemic cooling by circulating a cold liquid through a nasal catheter looped through the patient's nasal cavities and around the nasal septum. The nasal catheter is inserted into the patient's first nostril, advanced through the nasal cavity, around the nasal septum and out of the patient's second nostril. A cold fluid having a temperature between about −20° C. and about 37° C. is flowed though a lumen in the nasal catheter to cool the nasal cavity. The nasal catheter may have one or more flexible balloons mounted on the catheter such that when the catheter is looped around the nasal septum, the balloon(s) are positioned in a portion of the patient's first and second nasal cavities. When a cold liquid is circulated through the catheter lumen, the flexible balloons expand to a contact the inner walls of the nasal cavities and provide direct cooling of the nasal cavities.
