Apollo Safety Features
Designed to Support:
Increased patient safety
Maximum machine availability in
unlikely events of failures at all
times independent of the existing
cause

Apollo
Safety Features
10.1 Emergency Start
The emergency start procedure shortens the self test when the Apollo
must be operational immediately. The emergency start procedure can be
performed up to ten times in succession. After ten cancellations, the system will
not allow another cancellation and a complete self test must be performed.
NOTE: This procedure should only be used in emergency situations!

Safety Features
10.1 Emergency Start
Power on the machine by pressing the main power switch on the
front of the machine. An acoustic tone sounds.
2. Check that all vaporizers are closed.
Set an appropriate fresh gas flow using the oxygen flow control
knob. Verify adequate flow by checking the total flow meter.
4. Start manual ventilation.
5. Continue manual ventilation while the software is internally
loaded and the electronics are tested. After about 35 seconds,
the Check List screen appears.
6. Press the >Cancel Test< key on the Check List screen. The
machine runs through a minimal self test that lasts about 10
seconds. Manual ventilation is interrupted during this time, but
spontaneous breathing can continue. After the minimal self test,
the workstation switches to standby mode.

Safety Features
10.2 Mains Power Failure
In the event of power failure the Apollo automatically switches to
the built-in uninterruptible power supply (battery backup). Provided
that the battery is fully charged, operation will be continued for at
least 30 minutes (up to 90 minutes, depending on the ventilation
parameters).
The message “POWER FAIL” is displayed in the status field on the screen,
together with the remaining battery capacity in percent.

Safety Features
10.2 Mains Power Failure
If the battery is almost depleted, the message “BATTERY LOW”
will be displayed. Apollo permits manual ventilation with 100% O2
in the event of a power failure and depleted battery. The fresh gas
measurements, ventilator, and monitoring are inactive.
In case of complete power failure:
Close N2O and AIR flow valves
Check vaporizer settings
Open O2 flow to the desired level (using total flow meter)
Ventilate patient manually

Safety Features
10.3 Gas Supply Failure
If the gas supply fails, the Apollo displays a message in the status field at the top of the screen,
corresponding to the failed gas:
“NO AIR SUPPLY” “NO N2O SUPPLY” or “NO O2SUPPLY”
Open the valve on the corresponding backup cylinder at the back of the machine
Restore the central pipeline gas supply
If there is no cylinder backup supply for the failed gas, the corresponding LED on the front panel
of the machine will flash red.
In case of N2O or air failure, 100% O2 should be delivered; be sure to set the O2 to an
appropriate flow.
In case of O2 failure, the SORC prevents hypoxic gas mixtures.
Oxygen must be restored immediately.

Safety Features
10.4 Ventilator Failure
If the ventilator fails, the message “VENTILATOR FAIL” is displayed in the
alarm field on the screen. The ventilation soft keys are removed from the
screen and a prompt appears advising the user how to proceed:
“Ventilator failure!”
Only manual ventilation available.
The machine automatically switches to Man/Spont mode:
• Ventilate the patient manually
• If pressure or volume monitoring fails, adequate substitute
monitoring must be ensured.

Apollo
Safety Features
10.5 Fresh Gas Delivery Failure
If the fresh gas mixer fails, the following message is displayed in the
status field on the screen: “GAS MIXER FAIL” and the numerical values for the
fresh gas flows appear grayed out to indicate that they may be inaccurate. The
current ventilation mode remains active.
• Close N2O and air flow control valves
• Check vaporizer setting
• Set O2 flow to the desired level using the total flow meter
NOTE: Refer to the total flow meter for approximate total flow.

Apollo
Safety Features
10.6 Ventilator and Fresh Gas Delivery Failure
If both the ventilator and gas mixer fail, the following message is displayed in
the status field on the screen: “GAS + VENT FAIL”.
The ventilation soft keys are removed from the screen and a prompt appears
advising the user how to proceed:
“Ventilator failure! Only manual ventilation possible.”
The machine automatically switches to Monitoring mode.
• Close N2O and air flow valves
• Check vaporizer setting
• Set O2 flow to the desired level using the total flow meter
• Ventilate the patient manually

Apollo
Safety Features
10.7 Display Failure
If there is no display on the monitor screen:
• Switch the machine off.
• Set O2 flow to the desired level using the total flow meter.
• Check the vaporizer setting.
• Ventilate patient manually.
• Provide adequate substitute monitoring.

Safety Features
10.8 User Interface Failure
If the keypads, confirm knob, or flow control knobs are
not operational:
• Select the monitoring mode.
• Ventilate patient manually.
Observe the total flow meter for approximate flow!

Safety Features
10.9 System Failure
If the system no longer responds to an action:
1. Ventilate the patient manually.
2. Switch the machine off and on again.
3. Cancel the self test.
4. Check the vaporizer setting.
5. Close all flow controls (except O2), and run 100% O2.
If the breathing bag does not fill with fresh gas or manual ventilation is not
possible:
• check the oxygen supply; open cylinder valves if necessary
If fresh gas is still not delivered:
• close all flow controls
• disconnect patient from workstation and use another device
• turn workstation off
