Checking central gas supply and
cylinder supply
• Connect hose fittings for O2, N2O and Air
tocorrespondingfittingsonthebackof
thedevice.
• Plug wall fittings for O2, Air and N2O into
thecentralgassupplywalloutlets.
• Observe the pipeline icons on the mixer unit
display. If the pipelines are not connected,
therewillbeaXthroughtheicon.
• Open the cylinder valves.
• Observe the cylinder icons on the mixer unit
display. If the cylinders are not connected,
therewillbeaXthroughtheicon
• Close the cylinders.
The specific pressures for the pipelines and
the cylinders can be seen on the main screen
of the device.
Checking the electrical supply
• Ensure the mains power cord is plugged in.
• Observe the plug icon on the mixer unit
screen. If the mains power is not connected,
therewillbeaXthroughtheicon.
Checking the compact breathing system
• Ensure the compact breathing system is
connectedandlockedintoplace.
• Check the status of the soda lime, breathing
bagandpatienthoses.
In addition…..
• Test the O2flush.
• Check the Add O2.
• Ensure the vaporisers are in position, locked
andfilled.
• Check the water trap and the sample gas
lineconnection.
• Check the function of the suction system
• Connect and check the AGS system.
Preparation for Use
Gas Block
Mixer Unit

11
Prepare the device for the entire
system test
• Press the power on button on the system
screen.
• Occlude the Y piece on the occlusion port
• Set the APL valve to 30.
• Close the Add O2.
• Confirm the checklist if all the points are
checked and ok.
Entire system test
• Press the entire system test and confirm by
pressingtherotaryknobtostartthetest.
• The entire system test includes a pre-test.
This will identify any common errors that
occur during the self test (for example,
incorrect setting of the APL valve) within
60 seconds, allowing the user to rectify them
quickly before continuing the entire system
test. In the event of such a failure, resolve
the issue and repeat the test.
Theleakage assistant will assist in
identifyingthelocationofanyleaksthat
occur in the breathing system. Press the
leakageassistantbuttonandfollowtheon
screeninstructions.
• On completion of the pre-test, the entire test
system will continue automatically.
Leakage test
• Complete after changing breathing circuits

Operation
New case
The start up dialogue appears by touching
the start button on the screen (located in the
bottom right hand corner)
• Select the required profile – one of 3
on the screen. The default profile is in
dark green.
• Set the patients details (weight, age, height)
by touching the relevant button on the
screen, using the rotary knob to set the
required value and confirming by pressing
the rotary knob.
• Check that the gas delivery and ventilator
settings are appropriate for the patient.
• Start by selecting the ventilation mode
required and confirming with the rotary
knob.
Setting fresh gas delivery
• To change the carrier gas used, select
the gas required and confirm by pressing
the rotary knob.
• To adjust O2concentration, change the
concentration as required and confirm by
pressing the rotary knob.
• To adjust the fresh gas flow, change the
flow as required and confirm by pressing
the rotary knob.

14
Hypoxic guard function (SORC)
The Perseus A500 is fitted with a hypoxic
guard function (SORC). This is an electronic
O2minimum delivery system that guarantees
at least 25% O2whenever N2O is used as the
carrier gas. This prevents the delivery of hypoxic
gas mixtures.
Selecting a ventilation mode
Spontaneous breathing (Spont)
• Select man/spont and confirm.
• Adjust the APL valve to SPONT –
the breathing system is now open for
spontaneous breathing.
Manual ventilation (Man)
• Select man/spont and confirm
• Switch the APL valve to MAN and adjust
accordingly.
• Note - the breathing system pressure can
be quickly released by pulling the APL valve
upwards.
Mechanical ventilation
• Select the ventilation mode required by
pressing the appropriate tab.
• Set the ventilation parameters as required
by selecting the parameter, adjusting and
confirming by pressing the rotary knob
• Confirm the ventilation mode by pressing
the rotary knob.
When changing between different modes,
the parameters from the previous mode are
transferred directly or suitably derived.
Operation

15
External fresh gas outlet
The Perseus A500 has an external fresh gas
outlet to facilitate the use of non rebreathing
systems such as an Ayres T piece.
• Prepare the circuit in accordance with
the manufacturers recommendations.
• Attach the circuit to the external fresh gas
outlet on the Perseus A500.
• Select the Ext FG outlet tab on the screen
and confirm by pressing the rotary knob.
Switching to standby
At the end of a case, stop ventilation by
pressing the start/standby button in the bottom
right hand corner of the screen and confirm by
pressing the rotary knob. Fresh gas delivery
ceases at this point.
Switching the device off
• Switch the Perseus A500 to standby as
described above.
• Press the green on/off hard key located on
the bottom left hand corner of the screen
and follow the on screen instructions.

Alarms
Alarm priorities
Alarms are displayed in 3 priorities:
Priority Display Tone Sequence Significance
Highest Red Continuous Immediateactionrequired
Medium Yellow Every 30 seconds Action required at earliest
convenience
Low Cyan Once Attention&actionifnecessary
If an alarm situation occurs you will be notified
in 2 ways:
• The relevant parameter field will flash in the
appropriate colour. Press the parameter box
to access the alarm information.
• An alarm message appears at the top of the
screen in an appropriately coloured box.
Press this box to access the alarm
information.
Changing alarm limits
To change an alarm limit either
• Press the Alarms key at the top right hand
side of the screen.
Or
• Press the parameter box for direct access
to the specific alarm limit.

17
Emergency start up
• Adjust the APL valve according to
thepatient.
• Connect the patient.
• Switch to Add.O2on the mixer unit.
• Set appropriate O2flow on the flowtube.
Note: The O2is channelled through the
vaporiser which should also be set accordingly
• Ventilate the patient manually viewing the
airway pressure display on the mixer
unitscreen.
• Press on/off switch to power on the device.
• The standby screen will appear after
approximately20seconds.Youmaystart
thecaseinthenormalmanner.
• Switch off the Add O2.
Note: A self test must be performed at the
earliest opportunity.
Power failure
In the event of central power supply failure,
the message POWER FAILURE appears on
the screen.
If the battery is fully charges, the device can
continue to operate for at least 30 minutes.
The remaining battery capacity will be displayed
on the mixer unit screen. When the battery is
almost empty, the message BATTERY LOW and
then BATTERY VERY LOW will be displayed.
If the battery is completely empty, the device
will automatically switch to Man/Spont. Manual
ventilation is available at any time.
• Switch to Add O2on the mixer unit and set
thedesiredO
2flow via the flowtube.
• The O2is channelled via the vaporiser.
Emergency Scenarios
POWER FAIL

18
Gas supply failure
If the central gas supply fails, the message No
N2O, O2or AIR delivery appears on the screen.
Air or O2will be delivered in place of the gas
mixture previously delivered; the amount of
fresh gas (l/min) will remain the same.
100% Air will be delivered if O2fails.
100% O2will be delivered if N2O or Air fails.
• Open the appropriate back up cylinder or
reconnect the central gas supply.
If the carrier gas N2O fails, you are able to use
Air and vice versa.
Ventilator failure
In case of ventilator error, the ventilator will stop
and display the error message VENTILATOR
FAILURE on the screen.
Fresh gas flow and monitoring functionality are
not affected.
Switch to Man/Spont and manually ventilate
the patient.
Mixer failure
The message GAS MIXER FAILURE appears
on the screen.
• Ventilation and monitoring functionality are
not affected.
• Switch to Add O2on the mixer unit screen
and set the required O2flow on the
flowtube. The O2flow is channelled via
the vaporiser.
