Checking Cylinder Supply
and Central Gas Supply
(if available)
• Connect hose ttings for O2
Air and N2O to corresponding
ttings on the back of the
machine (1).
• Plug wall ttings for O2, Air
and N2O into central supply
wall outlets.
• Observe LEDs for the supply
pressure, they must be green (2).
• Open back up gas cylinder valves
to check cylinder pressure.
• The LEDs for the O2, Air and
N
2O cylinder pressure must
be green (3).
• Close the cylinder pressure
valves again.
Checking Electrical Supply
• Ensure that main power cord
is plugged in.
• Green LED is illuminated
whenever main power is
available (4).

Preparation for Use

Checking Compact Breathing
System
• Ensure that the compact
breathing system (1) is connected
and the ventilator is locked in place.
• Check status of CO2
absorbent (2), breathing bag
and patient hoses.
In Addition …
• Test the oxygen ush (3).
• Check oxygen safety control (4).
• Make sure vaporisers are in
position, locked and lled (5).
• Check water trap level and the
sample gas line connection (6).
• Check function of suction
system (7). Your suction system may
differ from the system shown.
• Connect anaesthetic gas
scavenging system.

Preparation for Use

Start Up
• Switch on Primus using the
ON/OFF switch (1).
• Close Y-piece (place rmly
onto the corresponding cone
of the breathing system).
• Set the APL valve to MAN
and 30 mbar (2). There are
two versions of the APL valve.
Your version may differ from
the one shown.
• Close oxygen safety control
valve (3).
• Conrm the checklist,
if all points are OK.
• Primus will run internal
system tests.
Note: During this start up
procedure and up until the
checklist is conrmed, manual
ventilation is always possible. The
oxygen safety ow can be set to
0 -12 L/min and will be channelled
through the vaporiser.

Start Up

Self Test
• Follow the self test instructions
on the screen.
Information about system leaks
and compliance will be displayed.
Primus will accept leaks of up to
150 mL/min. The most common
causes of leakage are:
• Faulty breathing hoses or breathing bag
• Sample gas line
• Filter
• Incorrectly connected absorber
• Flow sensors
• Breathing system
• Vaporisers
• Water trap
• Oxygen sensor
Potential Test Results
All test results are colour coded and
are displayed next to each specic
test function. An advisory window
containing information on how to
remedy the problem accompanies
any error detected during the self test.

Start Up

Leak Test
The leak test should be carried out after the patient hoses, vaporisers or soda lime have
been replaced. In addition, it should be performed following the self test.
To perform the leak test:
• In the standby screen, press the leak test soft key
• Follow the on screen instructions
• Push the rotary control knob to start the leak test
Self test results can be displayed, see page 7

Start Up

Standby Screen
Primus activates the standby mode after successful test completion,
and will display the standby screen.
From the standby screen, you can access the following functions:
• Pre set carrier gas, O2 concentration and fresh gas ow
• Set age
• Set ideal body weight
• Restore site default settings
• Set alarm limits
• Self test results display
• Perform the leak test
• Delete trends
• Default conguration
(password protected - held by Key Users and Dräger)
• Access monitoring mode
Monitoring Mode
In monitoring mode, the Primus will measure and display gas measurements.
There is no fresh gas delivery or ventilation capability. If ventilation is required,
set the appropriate gas ow, select the appropriate ventilation mode and
press the rotary control knob to conrm.
9
Operation

• To begin monitoring without
ventilation and fresh gas ow
press the key while in standby.
• To return to standby: press the
key again and conrm using
the rotary knob.
Setting Fresh Gas
Concentrations
These may be preset in standby.
• Carrier gas: press and conrm
either N2O or Air (1).
• Oxygen concentration: press
O
2%, set the concentration
with the rotary knob and
conrm (2).
• Fresh gas ow: press ow
l/min, set desired ow
and conrm (3).
• Fresh gas ow will start as
soon as a ventilation mode
is activated and is indicated
in virtual ow tubes on display screen.

Operation

Hypoxic Guard Function (SORC)
Primus is tted with a hypoxic guard function
(SORC). This is an electronic O2minimum
delivery system that guarantees at least
25% O2 whenever N20 is used as the
carrier gas. This prevents the delivery
of hypoxic gas mixtures.
11
Operation

Spontaneous Breathing
“SPONT”
• Switch the APL (pressure limiting
valve) to “SPONT”. The
breathing system is open for
spontaneous breathing.
• Press the “Man. Spont.”
key and conrm with the
rotary knob.
Manual Ventilation “MAN”
• Switch APL pressure limiting
valve to “MAN”. There are
two types of APL. Please
familiarise yourself with
your own device.
• Press “Man. Spont.” key and
conrm with the rotary knob.
Note: the breathing system
can be quickly depressurised
by pressing the lever of the
APL valve or pulling the APL
valve upwards dependant on
the type of APL valve installed.
12
Operation

Mechanical Ventilation
• Press the desired key e.g.
Press. Mode.
• Using the soft key, select the
ventilation parameter to be
preset, then set and conrm
with the rotary knob.
• To start the ventilation mode
conrm with the rotary knob.
To return to Man/Spont mode:
• Press Man/Spont hard key
• Press rotary control knob to conrm
Fresh Gas Outlet (optional)
The Primus has an external fresh
gas outlet to allow the user to use
non rebreathing systems such as a
Bain circuit or Ayres T-piece.

with the manufacturers instructions.
• Attach the circuit to the external fresh
gas outlet located on the left hand side
of the Primus.
• Press the external fresh gas outlet hard
key and conrm by pressing the rotary
control knob.

Emergency Scenarios

17
Power Failure
In the event of central power supply
the message “POWER FAIL”
appears on the screen.
If the battery is fully charged,
Primus can continue operating for
at least 30 minutes (typically
90 minutes). Remaining battery
capacity will be shown on the
screen. When the battery is
almost empty, the message
BATTERY LOW will be displayed.
If the battery is completely
empty, the device automatically
switches to Man.Spont.
Manual ventilation is available at
any time.
• Release the oxygen safety
control knob by pressing and
set to desired oxygen ow,
between 0 and 12 l/min. The
oxygen ow is channelled
through the vaporiser.
Emergency Scenarios

18
Gas Supply Failure
If the central gas supply fails, the
message “No N2O, O2 or AIR
DELIVERY” appears on the
screen.
Air or oxygen will be delivered in
place of the gas mixture
previously delivered; the amount
of fresh gas ow (l/min)
will remain the same.
100% Air will be delivered if
O2fails.
100% O2 will be delivered if N2O
or air fails.
• Open the appropriate backup
gas cylinder valve for O2or
N
2O, or reconnect the central
gas supply.
If the carrier gas N2O fails, you are
able to use Air and vice versa.
Emergency Scenarios

19
Ventilator Failure
In case of ventilator error, the
ventilator will stop and display the
error message “VENTILATOR
FAIL” on the screen.
• Fresh gas ow and full
monitoring functionality are
not affected.
Operation automatically switches
to Man. Spont.; only manual
ventilation is possible.
Emergency Scenarios

20
Mixer Failure
The message “GAS MIXER FAIL”
appears on the screen.
• Ventilation and full monitoring
functionality are not affected.
• Release the oxygen safety
control knob by pressing and
set to desired oxygen ow,
between 0 and 12 L/min.
The oxygen ow is channelled
through the vaporiser.
