What is the effect of a safety valve for breathing anesthesia and a pressure reducing valve?
Safety valve: APL valve, control the appropriate airway pressure, to prevent the airway pressure high blasting the lungs
Pressure reducing valve: the center of the high oxygen pressure to low pressure, is anesthesia machine internal device, can not be set
If it is machine-controlled breathing, it does not matter, the general airway pressure will not exceed 30, anesthesia machine generally set the air pressure limit of 25, that is more than 25 of the gas automatically let go, will not produce lung injury to patients
Is the pressure limiting valve, if you do manual breathing, then limit the valve at least down 30CMH2O, or else can not effectively control breathing ah
