Mindray A9 Operating Instructions

Basic Ventilation Test Preoperative Tests
5 - 8 Operator’s Manual of Anesthesia System
NOTE: Different from O
2
pipeline supply, when N
2
O supply is disconnected,
the anesthesia system with no pressure sensor configured will issue no
alarms related to N
2
O pressure as N
2
O pressure decreases.
1. Connect O
2
and N
2
O pipeline supplies.
2. If the anesthesia system has been configured with backup gas cylinders, turn off the valves of all
the backup gas cylinders.
3. Set the System switch to the On position.
4. Select the soft key in Fresh Gas Flow display zone, and set the [Control Mode] on the pop-up
screen to [Direct Flow].
5. Set [Balance Gas] to [N
2
O].
6. Set the N
2
O flow to 6 L/min.
7. Check whether the readings of the N
2
O pipeline pressure gauges are within the range of 280 to
600 kPa (40 to 87 psi).
8. Disconnect the N
2
O pipeline supply.
9. With the N
2
O pressure decreases, the O
2
flow remains unchanged and the N
2
O flow becomes
zero. Meanwhile, the anesthesia system with a pressure sensor configured will issue the alarm of
[N
2
O Supply Failure].
10. Ensure that the N
2
O gauge reading decreases to zero.
5.6.3 Air Pipeline Test
NOTE: Different from O
2
pipeline supply, when air supply is disconnected, the
anesthesia system with no pressure sensor configured will issue no
alarms related to air pressure as air pressure decreases.
1. Connect the pipelined Air supply.
2. If the anesthesia system has been configured with backup gas cylinders, turn off the valves of all
the backup gas cylinders.
3. Set the System switch to the On position.
4. Select the soft key in Fresh Gas Flow display zone, and set the [Control Mode] on the pop-up
screen to [Direct Flow].
5. Set the Balance Gas to AIR.
6. Set the Air flow to 6 L/min.
7. Check that the Air pipeline pressure gauges show 280 to 600 kPa (40 to 87 psi).
8. Disconnect the pipelined Air supply.
9. With the air pressure decreases, the anesthesia system with a pressure sensor configured will
issue the alarm of [Air Supply Failure].
10. Ensure that the Air gauge decreases to zero.
5.7 Basic Ventilation Test
1. Attach a breathing circuit and breathing bag.
2. Attach an adult test lung or breathing bag to the patient end of the Y-fitting of the breathing
circuit.
3. Set the O
2
flow to 3 L/min and set the N
2
O and air flows to zero.
