A generator for use in nasal continuous positive airway pressure and nasal intermittent positive pressure ventilation therapies in which a first channel 4 for transporting fresh gas and a second channel 5 for communicating proximal pressure levels are ported for tube connections being made within the third channel 3 for carrying exhaled gas. The device extends over the portion of length that is within the patient's environment. The 3 channels may connect to a manifold with 3 separate external patient circuit connection ports 8, 9 and 10. The arrangement allows for heat exchange between the inhalation and exhalation gasses to reduce the temperature differential and help eliminate condensation and is further designed to improve the speed and ease of use. |
