All
What preparations should be made before starting to use the equipment?
All components are securely and correctly installed and connected;
The breathing circuit is intact and securely and correctly connected;
Gas supply connections are correct;
The power cord plug is securely connected to the wall outlet. Turn on the power switch; the ventilator display should illuminate.
Gas Supply Check
1. The supply pressure from the central gas supply system should be 440 kPa ± 160 kPa (280 kPa to 600 kPa).
If using cylinder gas supply, the cylinder should be fully charged or sufficiently filled. The output pressure of the cylinder pressure reducer should be adjusted to 440 kPa.
Optional: Press the air compressor switch to the ON position. Once the air compressor stabilizes, observe the pressure gauge on its control panel; the pressure should read 0.4 MPa.
Ventilation Function Check
1. Perform primary ventilation function checks as follows:
Connect the bag to the Y-connector. Turn on the power and gas supply.
After startup, verify that ventilation parameters—including tidal volume, frequency, minute ventilation, oxygen concentration, and airway pressure—are normal under each ventilation mode;
Under APNEA (A/C) controlled ventilation, inhale at the Y-shaped connector to verify proper trigger function.
How to properly connect the gas supply to an anesthesia machine?
The oxygen source for this unit may be either a central gas supply system or high-pressure cylinder oxygen.
If using a central gas supply system as the source, simply connect the O2 (oxygen) inlet fitting on the rear of the unit to the corresponding supply system using a high-pressure oxygen hose. However, the supply pressure must meet the unit's requirements.
If using high-pressure cylinder oxygen as the gas source, a pressure reducer must be employed. Inspect and adjust the pressure reducer to ensure the output pressure is within the range of 440 kPa ± 160 kPa (280 kPa to 600 kPa). Then connect the high-pressure oxygen hose to the O2 (oxygen) input port on the back of the machine.
The air source may be supplied by the air compressor included with this unit or by a central air supply system, but the supply pressure must meet the machine's requirements.
(Note: The pressure difference between the oxygen and air sources should be less than 0.1 MPa.)
