Feature:
　　A. HF JV(High-frequency jet ventilation) with pressure support, which can supply the higher inspiration pressure so that the patients can inspire sufficient oxygen with a wet finger.
　　B. Opening airway. The ventilation can be made with high frequency and little tidal volume and low airway pressure, which is good to increase the blood oxygen density.
　　C. Ventilation mode through nasal vestibule without effect which can avoid from tracheotomy and endotracheal tube so as to decrease patient's pain and the effectiveness of oxygen feeding is very good, The patient can talk, drink and eat, when ventilating.
　　D. Continuous positive airway pressure with adjustable oxygen density plus effective humidifier can show the feature of CPAP better.
　　E. The multi-functional humidifier adaptor can be connected with any type of humidifier by trachea intubation of national or international standard.
　　F. The pressure humidifier has knob to manipulate the air volume and has the delicacy alarm with sound and light for no power or gas.
