AX- 900 adheres to the classic gas control method and also posess the accuracy as well as convenience of advanced electronic monitoring and control.
AX-900 has designed a number of quality control processes for the use of inhaled anesthetics, fresh gases and soda lime, which enables medical staff to avoid risks in operation and solve hidden dangers before the alarm.
Why Insist On the Classic Ascending Bellows Pneumatic Drive Electronic Control Technology?
The ascending bellows pneumatic electronic control technology provides a more compact circuit and a smaller loop cavity, which realizes accurate ventilation. 
Simple structure is convenient for disassembly and disinfection.
Manual ventilation is separated from mechanical ventilation to reduce the occurrence of misoperation. 
Provides more stable ventilation and sharper triggering under SIMV mode and PSV mode. 
No need to pre-inflate, machine will ventilate when you start it up, which is conducive to rapid rescue. 
Provide higher compression capacity. 
PEEP facilates lung protection and recrutiment maneuvers.
Breakthrough of Pneumatic Drive Electronic Control Technology：
X-900 adheres to the mature pneumatic electronic control technology of AX series, and has made breakthroughs in precision. 
 AX-900 can perform a 5ml low tidal volume ventilation under PCV mode during infant anesthesia, and the maximum tidal volume can reach 1500ml, coupled with stable pressure control enable AX-900 to achieve full age coverage.
Advanced Fresh Gas Control System：
Anesthesia doctor is able to set oxygen concentration directly, then the system automatically adjust the ratio of oxygen gas and balance gas. AX-900 can also realize real-time correction of oxygen concentration and total flow, correcting flow error that caused by fluid inertia.
Why Should We Change the Operation Method of Electronic Flow Meter？
AX-900 also provides a Best Flow Indicator Tool that gives accurate flow of current anesthesia ventilation. It improves the efficiency of anesthesia, implements precise anesthesia, and anesthesiologists can try low-flow anesthesia accordingly. The Best Flow Indicator Tool uses the color spectrum diagram to fit the design idea of alarm color, and more intuitively present the current flow value.
Quality Control Management:AX-900 has made multiple risk quality control in equipment's inspection and operation. In case of misoperation, equipment failure, exhaustion of gas source/consumables, etc., early warning will be given to urge the anesthesiologist to check and handle the hidden dangers before the alarm occurs.
Power-on self-test and leak test system: simpler design provide more convenience for medical staff.
Intraoperative anesthetic gas usage statistics: easy for medical staff to know the cumulative dose of medication .
Statistics of soda lime consumption: early warning of the consumption of soda lime to prevent CO2 retention.
Ventilator risk operation reminder: misoperation warning, risk operation prompt check, reduce operation accident. 
Shutdown delay: avoid accidental ventilation stop caused by misoperation.
