Feature: 
A. The device adopts impulse jet oxygen feeding technique with great flow rate of oxygen feeding in a shot while, when feeding oxygen, it adopts change mode major in reflux and many kinds of gas flow mechanism such as convection, laminar flow, sheet flow and so on concurrently, which is good to increase partial pressure of oxygen rapidly, At the same time fluctuation of thorax caused by increasing oxygen flow into airway is good to let out CO2. 
B. Jet oxygen feeding is supported by pressure when inspiration and secure certain PEEP effect when feeding oxygen, So as to reach good effectiveness of oxygen feeding. 
C. Accumulator jar, it can be used while being charged and can last for four hours after having been charged. 
D. Alarm system with sound and light when lack of electric quantity or airway pressure. 
E. 300CG chooses digital display of import pressure sensor. 
F. 300CG has three kinds of airway limited pressure alarm for adult, child and infant. 
G. The device disposes pressure humidifier which has good humidigying effectiveness.
