3.10 Alarm tests
1. Connect a test lung to the patient connection.
2. Set the system switch to On.
3. Set the controls:
• Ventilation Mode: Volume control (select from main menu)
• Ventilator:
– Tidal Vol: 400 mL
– Rate: 12
– I:E Ratio: 1:2
– P
max
: 40 cm H
2
O
– PEEP: OFF (if equipped)
• Anesthesia Machine:
– O
2
flow: zero flow
– All other gases: OFF
– If equipped, ACGO selector switch to the breathing system.
4. Push O
2
flush to fill the bellows.
5. Set the Bag/Vent switch to Bag and back to Vent.
6. Make sure that:
• Mechanical ventilator starts.
• A subatmospheric pressure alarm does not occur.
Note: With active gas scavenging, too much scavenging flow
can cause subatmospheric alarm.
• The ventilator displays the correct data.
• The bellows inflate and deflate during mechanical ventilation.
7. Set the O
2
flow control to 5 L/min.
8. Make sure that:
• The end expiratory pressure is approximately 2 cm H
2
O.
Note: Positive end expiratory pressure when PEEP is off
may indicate that the scavenging system is not removing
enough gas, if the PEEP option is enabled.
• The ventilator displays the correct data.
• The bellows inflate and deflate during mechanical ventilation.
9. Test the low minute volume alarm:
• Go to alarms menu.
• Set the alarm limit for low minute volume to 6.0 L/min.
• Make sure that a low minute volume alarm occurs.
• Go to the alarms menu.
• Set the low minute volume alarm to 0.1 L/min.
10. Test the high airway pressure alarm:
•Set P
max
to less than the peak airway pressure.
• Make sure that the high airway pressure alarm occurs.
•Set P
max
to correct level.
11. Test the apnea and low airway pressure alarms:
• Turn all flow controls fully clockwise.
• Set the Bag/Vent switch to Bag.
