Mindray A9 Operating Instructions

Operator’s Manual of Anesthesia System 5 - 9
Preoperative Tests Backup Gas Cylinder Test
4. Set the ventilator controls according to the following table:
5. Select PCV and begin ventilation.
6. Verify that the breathing bag at the patient end of the Y-fitting of the breathing circuit inflates
and deflates and that the PLAT monitoring on the display and the PAW gauge reading are
consistent with the Pinsp setting.
5.8 Backup Gas Cylinder Test
NOTE: No backup gas cylinder test is required for an anesthesia system not
configured with backup gas cylinders.
5.8.1 Check Cylinder Pressure
1. Set the system switch to the Off position and connect the gas cylinder to check.
2. Open the valve of each gas cylinder using the attached wrench.
3. Make sure that each gas cylinder has adequate pressure. In case of inadequate pressure
discovered in any gas cylinder, close the valve for the specific cylinder and replace the cylinder
with a fully-inflated one.
• Input range of O
2
cylinder: 6.9 to 20 MPa (1000 - 2900 psi)
• Input range of N
2
O cylinder: 4.2 to 6 MPa (600 - 870 psi)
• Input range of air cylinder: 6.9 to 20 MPa (1000 - 2900 psi)
4. Close the valves of all cylinders.
5.8.2 High Pressure Leak Test of O
2
Cylinders
1. Set the system switch to the Off position and disconnect the O
2
pipeline supply.
2. Open the valve of the O
2
cylinder.
3. Record the current pressure of the cylinder.
4. Close the valve of the O
2
cylinder.
5. Record the cylinder pressure after one minute.
If the pressure reduction of the backup gas cylinder exceeds 1.25 MPa (181.3 psi), install a new
cylinder gasket. Repeat Steps 1 to 5. If the leak persists, stop using the backup gas cylinder
supply system.
5.8.3 High Pressure Leak Test of N
2
O Cylinders
1. Set the system switch to the Off position and disconnect the N
2
O pipeline supply.
2. Open the valve of the N
2
O cylinder.
