The Importance of
Patient Monitoring
WARNING
Anaesthetic systems have the capability to
deliver mixtures of gases and vapours to the
patient which could cause injury or death
unless controlled by a qualified anaesthetist.
There can be considerable variation in the
effect of anaesthetic drugs on individual
patients so that the setting and observation
of control levels on the anaesthesia systems
does not in itself ensure total patient safety.
Anaesthesia system monitors and patient
monitors are very desirable aids for the
anaesthetist but are not true clinical
monitors as the condition of the patient is
also dependent on his respiration and the
functioning of his cardio-vascular system.
IT IS ESSENTIAL THAT THESE ELEMENTS
ARE MONITORED FREQUENTLY AND
REGULARLY AND THAT ANY
OBSERVATIONS ARE GIVEN PRECEDENCE
OVER MACHINE CONTROL PARAMETERS
IN JUDGING THE STATE OF A CLINICAL
PROCEDURE.
Before using any monitoring system or
device with the anaesthetic machine, the
user must check that it conforms to the
relevant standard, as listed in the table
below.

1. WARNINGS AND CAUTIONS
The following WARNINGS and
CAUTIONS must be read and
understood before using this anaesthetic
apparatus.
WARNINGS
1. This apparatus is designed for use only
with non flammable anaesthetic agents.
It must not be used with or in close
proximity to flammable anaesthetic
agents, due to a possible fire or
explosion hazard.
2. Exterior panels must not be removed by
unauthorised personnel and the
apparatus must not be operated with
such panels missing.
On machines with an electrical power
supply, unauthorised personnel must
not attempt to access fuses or other
electrical components. There is a
possible electric shock hazard.
3. No oil, grease or other flammable
lubricant or sealant must be used on any
part of the machine in close
proximity to medical gas distribution
components.
There is a risk of fire or explosion.
4. When attaching cylinders of medical
gases ensure that the machine yoke and
cylinder faces are dust free and clean
and that the sealing washer provided is
in position between the cylinder valve
and the yoke.
Tighten the yoke securely before
opening the cylinder valve. Dust and dirt
presents a fire hazard in the presence of
high pressure gas.
Leakage of high pressure gas can
cause serious injury.
5. Anaesthesia apparatus must be
connected to an anaesthetic gas
scavenging system (AGSS) to dispose of
waste gas and prevent possible health
hazards to operating room staff.
This requirement must be observed
during test procedures as well as
during use with a patient.
6. Prima SP series machines must only be
used with Delta vaporizers (or other
vaporizers approved by the
manufacturer) installed by means of the
Cagemount or Selectatec system.
Free-standing vaporizers may be
accidentally tipped, resulting in
excessive and uncalibrated volumes of
anaesthetic drug entering the breathing
system
Do not install or connect any vaporizers
of any description between the Common
Gas Outlet (CGO) and the breathing
system unless they are specifically
designed for such use.
(If this is done, the oxygen flush flow will
pass through the vaporizer and may
result in gross overdosage when the
flush valve is operated.)
7. The breathing system which conveys
gases from the anaesthetic machine to
the patient and disposes of expired
gases is a vital part of the anaesthetic
delivery system.
Because breathing systems require
frequent cleaning and disinfection they
are not a permanent part of the
anaesthetic machine and therefore
cannot be directly under the control of
the anaesthetic machine manufacturer.
However, we strongly recommend that
only breathing systems which have been
approved and authorised by Penlon for
use with the Prima SP range should be
employed.
This is particularly important when
mechanical ventilation is employed.
8. When mechanical ventilation is
employed the patient breathing system
must be connected directly to an overpressure relief valve to prevent the
possibility of barotrauma.
9. Always perform a pre-use check of the
machine, including vaporizers,
ventilator, circle absorber and monitors
before clinical use. Follow the pre-use
checklist (see section 5) as a minimum
requirement.
Many clinical incidents occur because of
a failure to check for correct function.
10. The machine must not be used if any of
the alarm, monitoring or protection
system devices are not functioning
correctly.
11. The gas supply failure systems within
the anaesthetic machine will not
necessarily operate as indicated in the
user manual during any procedures that
are outside the scope of the indications
for use of the machine:
2
WARNINGS AND CAUTIONS
(A) Machine set to deliver Air only
When the machine is operated with an Air
flow only, note that there may still be
retained oxygen in the system, and that the
visual O2 alarm will continue to indicate
green, even though oxygen is not being
delivered.
(B) Machine set to deliver Oxygen only
through Auxiliary Outlets
The oxygen failure alarm is designed to
operate during normal use of the machine,
i.e. when providing controlled
concentrations and flows of gases to a
patient breathing system, as described in
Section 2 (Purpose).
Do not use the machine solely to provide
large flows of oxygen, via the anaesthetic
machine auxiliary outlets, to external
devices which may not be equipped with a
supply failure alarm.
12. The machine must not be fitted with
more than four operator accessible
mains socket outlets. There is a risk of
an excessive leakage current.
13. The use of antistatic or electrically
conductive breathing hoses is not
recommended when using high
frequency electrical surgery equipment
(e.g. Diathermy). Burns may be
caused.
14. Before any electrically powered machine
is used clinically for the first time,
check that the hospital engineering
department has carried out an earth
continuity test.
15. Before using any additional electrical
equipment powered by the auxiliary
sockets on the machine, check that the
additional equipment is correctly wired
and is earthed through its plug.
A missing or defective protective earth
conductor may increase earth leakage
currents to the patient to values
exceeding the allowable limits,
resulting in ventricular fibrillation, or
interference with the pumping action of
the heart.
16. Additional equipment placed on the top
shelf must be securely attached.
Take care when moving a fully loaded
machine, particularly when negotiating
ramps.
Check that hoses or power leads are not
trailing on the floor.
17. Prima SP2/3 series anaesthetic
machines are not MRI compatible.
CAUTIONS
1. Flowmeter needle valves are designed to
seal with light torque and may be damaged
if tightened excessively.
Do not force the control knob past either the
fully open or fully closed positions.
2. Open cylinder valves slowly to avoid
damage to pressure reducing valves.
Ensure that cylinder valves are at least one
full turn open when in use.
3. Under no circumstances should anaesthetic
agents be used for cleaning purposes.
4. After use, always disconnect the machine
from the piped gas supply and/or close the
gas cylinder valves.
5. Mechanical AHD system - The oxygen flow
control is restricted to prevent the needle
valve from fully closing. This ensures a
minimum basal flow of oxygen.
DO NOT attempt to close the flow to zero.
Do not overtighten.
6. Compressed gas supplies must be clean
and dry.
7. When the auxiliary gas outlets are in use on
a machine with cylinder supply only, or if
the pipeline supply is not in use, check flow
rate requirements, and ensure that
adequate back-up cylinders are available.
8. The requirements of IEC 60601-1-1 apply to
any device connected to the auxillary
sockets. Users must be aware of the risks of
increased leakage currents when
equipment is connected to the auxillary
power sockets
9. In the event of malfunction of any device
powered by the auxiliary sockets, check if
the circuit breaker has tripped.
10. On machines with pipeline connections,
note that a malfunction of the central gas
supply within your facility may cause
immediate cessation of gas delivery and
total anaesthesia system failure.

2. PURPOSE
The Prima SP3 anaesthesia workstation
range is intended to provide controlled
concentrations and flows of anaesthesia
gases into a patient breathing system, from
where the anaesthesia ventilator and
breathing circuit will then deliver this fresh
gas mixture to the patient
Use the Prima SP3 in conjunction with
anaesthetic vaporizers, breathing hoses and
patient connection fittings which comply with
the relevant ISO standard or equivalent.
Depending upon the patient circuit selected,
the machines can be used in open, semiopen, semi-closed or closed circuit
configurations.
The range has been designed to give a wide
choice of configurations and accessories,
including:
Gas supplies
Up to four gases - oxygen, nitrous oxide, and
air, with optional fourth gas (see section 4).
Pin-index cylinder yokes, and provision for
up to three pipeline supply inlets.
Vaporizer mounting systems
Backbar manifold for Selectatec Compatible,
or Cagemount type vaporizers.
Anti-hypoxic Device (AHD)
The mechanical AHD system is designed to
minimise the risk of a hypoxic mixture
reaching the patient (see section 3).

3. DESCRIPTION
3.1 General Construction
Frame
The machine has a cast aluminium base,
extruded aluminium uprights, with aluminium
and plastic panels.
Mobility
Four castors are fitted, with a brake on each
of the front castors. The castors are five
inches diameter.
A footrest is built into the front of the
machine and, to aid manoeuvrability, two
handles are provided.
Mounting posts and brackets
A mounting system is built into each side
upright, to allow the use of pole-mount
brackets, V-brackets, and ventilator
mounting brackets.
The pole mount upright can be used to
mount an A200SP Absorber assembly.
Work surfaces
The work surface has raised edges to retain
instruments, vials etc.
A pull-out writing tablet is mounted under the
work surface.
1
Pipeline Inlets (1)
Up to three, rear mounted pipeline gas inlets
can be fitted.
Pipeline supply hoses are connected by
non-interchangeable, screw threaded
unions.
CAUTION
A malfunction of the central gas supply within
your facility may cause immediate cessation of
gas delivery and total anaesthesia system failure.
Filters
To prevent dirt entering the gas system,
cylinder yokes and pipeline inlets are fitted
with filters.
3.2 Gas Circuit
Gas Circuit Schematic
A gas circuit schematic is shown on the
following page.
Gas Supplies
A variety of cylinder and pipeline
combinations can be added to the basic
specification of oxygen and nitrous oxide
cylinder and pipeline supply.
For example, two extra gas cylinders
(choose from one additional oxygen, one
additional nitrous oxide, one air), and one
extra pipeline supply - Air.
Cylinder Yokes
The yokes are rear mounted and conform
with ISO standards for pin-index fitting.
To ensure that only cylinders of the
appropriate gas may be installed the yokes
are designed so that the retaining latch
cannot be closed unless the index pins are
fully engaged.
Gas Inlet Block
Each individual cylinder or pipeline supply,
is routed through a separate gas block.
Each gas block has an integral high
pressure gauge tapping for direct mounting
of a pressure gauge, and a non-return valve
to prevent back flow of gas.
In addition, cylinder gas blocks have a
diaphragm pressure regulator to reduce the
pressure of the compressed gas supply, and
a pressure relief valve, factory set to 517
kPa (75 psi). This prevents pressure build up
under the diaphragm should any leakage
develop across the reducing valve seat.
Secondary Pressure Regulator
A second stage regulator reduces the
pressure supplied to each flowmeter control
(see section 4).
The fitment of a secondary regulator for
oxygen and nitrous oxide enhances the
performance of the mechanical AHD system.
Secondary regulation of the air supply aids
the stabilisation of the output at the
flowmeter.

DESCRIPTION
3.3 Gas Supply Safety Devices
3.3.1 Gas Supply Cut-off Device
A gas cut-off device, triggered by low oxygen
supply pressure, cuts the supply of nitrous
oxide, and carbon dioxide or other fourth gas
(if fitted).
The cut-off operates when the oxygen
pressure falls to 200 ± 14 kPa (29 ± 2 psig).
Gas supplies are reinstated only when the
oxygen supply pressure rises above 227
kPa (33 psig).
3.3.2 Oxygen Supply Failure Warning
Whistle
WARNING: Refer to WARNING 11 (section 1).
A whistle gives an audible warning when
there is a reduction of oxygen supply
pressure.
Operated solely by the remaining oxygen in
the machine system, the warning whistle is
prolonged by an oxygen reservoir built into
the gas circuit, allowing a minimum warning
whistle of 7 seconds duration.
The whistle will start to sound when the
pressure falls to 200 ± 21 kPa (29 ± 3 psig),
and will continue to sound until the pressure
falls to approximately 70 kPa (10 psig).
Oxygen consumption of the whistle is
approximately 2 L/min when sounding and
nil at other times.
1
3.3.4 Oxygen Supply Visual Indicator
WARNING: Refer to WARNING 11 (section 1).
The indicator (1) is mounted on the front of
the machine and is operated from the
oxygen supply and shows GREEN when the
supply is at working pressure, and RED if the
pressure falls.
3.3.5 Mechanical AHD
A mechanical link between the oxygen
control valve and a needle valve in the
nitrous oxide flow ensures that the machine
delivers a fresh gas mixture with a minimum
30% (±3%) oxygen, irrespective of the flow
of nitrous oxide set by the anaesthetist.
With the nitrous oxide control valve fully
open, the oxygen and nitrous oxide flows are
then both controlled by the oxygen control
valve.
See section 3.4 for a full description
3.3.3 Fresh Gas Pressure Relief Valve
A pressure relief valve is mounted between
the vaporizer back bar and the common gas
outlet (CGO) on the inside face of the
machine right hand upright.
It is designed to prevent fresh gas being
delivered to the breathing system at
pressures exceeding 41 kPa (6 psi).
This valve also protects machine
components against excessive pressure in
the event of a total blockage of the CGO.
3.3.6 Low Pressure Gas Tubing
Diameter-indexed tubing is used for the low
pressure gas system - see section 4.
7
DESCRIPTION
3.4 Mechanical AHD
(Anti Hypoxic Device)
3.4.1 Introduction
The Mechanical AHD is housed within the
flowmeter module and comprises a gear
linkage between the oxygen control valve
and a needle valve in the nitrous oxide flow.
The system controls the relative flow rates of
oxygen and nitrous oxide.
A predetermined minimum oxygen
concentration of 30%
nitrous oxide mixture is maintained over the
flow range to prevent delivery of a hypoxic
mixture.
±3% in the oxygen /
1
limits the flow of nitrous oxide relative to the
flow of oxygen set by the user.
Note that this needle valve acts as the
primary nitrous oxide valve, and is actuated
only by movement of the oxygen control.
The nitrous oxide control knob on the
flowmeter module operates a secondary
needle valve in the nitrous oxide flow. It is
positioned downstream of the primary valve
and therefore is used only to restrict the flow
already set by the primary valve, which itself
has been determined by the position of the
oxygen control knob.
Therefore, for any oxygen flow set by the
user, the mixture delivered will still contain a
minimum 30%
nitrous oxide control knob fully open.
As the nitrous oxide knob is progressively
closed, the oxygen content of the mixture
increases to 100%.
3.4.4 Oxygen Basal Flow
To allow the system to function correctly, an
oxygen basal flow is continuously supplied.
±3% oxygen even with the
3.4.2 Gas Delivery Switch (1)
The Gas Delivery Switch (1) operates on the
oxygen supply and must be in the ‘On’
position for normal operation of the
anaesthetic machine.
Switch labelling: 1 Indicates On
0 Indicates Off
The switch consequently controls the supply
of all gases provided with a gas cut-off
triggered by a predetermined pressure level
within the oxygen supply (see section 3.3.1).
A whistle (oxygen failure warning whistle)
will sound briefly whenever the gas delivery
switch is turned on or off. Note that the
whistle functions continuously if the oxygen
supply fails (see section 3.3.2).
NOTE
The switch also controls the electrical supply to
the optional flowmeter lighting unit.
3.4.3 Gear Linkage and Nitrous Oxide
Control Valves
A gear linkage connects the oxygen control
knob on the flowmeter module and a needle
valve in the nitrous oxide flow. This linkage
Single Flow Tubes: 100 - 200 ml/min
Dual Cascade System Flow Tubes:
50 - 75 ml/min
This basal flow can only be turned on and off
by using the Gas Delivery Switch.
CAUTION
The oxygen control is restricted to prevent the
needle valve from fully closing. This ensures a
minimum oxygen basal flow.
DO NOT attempt to close the flow to zero. Do not
overtighten the knob.
3.5 Pressure Gauges
Pressure gauges (50 mm diameter) are
located on the front panel below the
flowmeter bank.
The gauge for Air is positioned between
oxygen and nitrous oxide. Unused gauge
positions are blanked out.
All pressure gauges are colour coded and
labelled for the gases whose pressures they
are indicating.
Cylinder gauges are marked: CYLINDER.
Pipeline gauges are marked: PIPELINE.
The gauges are calibrated in kPa x 100.

DESCRIPTION
3.6 Flowmeters and Controls
3.6.1 All models
The flowmeters, mounted behind the perspex
cover on the left hand side of the machine, are
length-indexed to prevent inadvertent, incorrect
installation.
All floats indicate flow rate in line with the upper
surface as shown below.
Each flow control valve is positioned directly
underneath the flow tube assembly to which it
corresponds, and the control knob is colour-coded
for the gas which it controls.
The oxygen flow control knob is made physically
distinguishable from the other flow controls for
identification by touch in accordance with ISO
standards.
When fitted, air and carbon dioxide flowmeters are
always installed in the inner positions on the
flowmeter assembly. These positions are blanked
out if air or carbon dioxide are not specified for the
machine.
Read flow at
this level
The gas delivery switch (see 3.4.2), positioned on
the front panel controls the supply of oxygen and
must be in the ON position for normal operation of
the machine.
Flow control of each gas is achieved by a needle
valve comprising a polished stainless steel needle
mounted concentrically in a common manifold
block. To minimise wear and material pick-up the
needle seat is manufactured from silver. The flow
control knob is turned counter-clockwise to
increase the gas flow.
CAUTION
Needle valves are designed to seal with light torque and
may be damaged if tightened excessively.
DO NOT USE EXCESSIVE FORCE.
3.6.2 Dual Cascade Flow Tubes
The flow of gas through dual cascade system flow
tubes always flows through the low-flow tube first.
The high-flow tube should not show any flow until
more than 1 L/min is set.
At flows above 1 L/min, the high-flow tube reading
indicates the rate of flow for that gas.
1
3.6.3 Auxiliary Oxygen Flowmeter
An oxygen flowmeter (1), with outlet, is mounted to
the left of the machine flowmeter bank.

DESCRIPTION
3.7 Vaporizers
CAUTION
Read the instruction manual supplied with the
vaporizer before clinical use.
3.7.1 Vaporizer Mounting Systems
Vaporizers for the administration of volatile
anaesthetic agents can be fitted as follows:
(a) Penlon Delta Selectatec compatible
vaporizers, mounted on a Selectatec
compatible universal backbar.
(b) Penlon Delta Cagemount vaporizers
mounted on a Modura rail (check that
relevant national standards for your
country allow fitment of more than one
cagemount type vaporizer).
WARNING
Vaporizers must always be securely mounted,
and never used free-standing.
Unmounted vaporizers may be accidentally
tipped resulting in uncalibrated and excessive
volumes of liquid anaesthetic drug entering
the breathing system.
3.7.3 Cagemount Vaporizer
Vaporizers fitted with cagemount tapers
have the male taper (inlet port) on the left,
and the female taper on the right (viewing
the front of the vaporizer).
It is recommended that detachable
cagemount connectors are retained with a
safety clip (catalogue number 52275) to
prevent inadvertent disconnection.
3.8 Common Gas Outlet (CGO)
1
Vaporizers of any description must not be
installed or connected between the Common
Gas Outlet (CGO) and the Breathing
System, unless they are specifically
designed for such use. (If this is done, the
oxygen flush flow will pass through the
vaporizer, and severe overdosage may
result).
3.7.2 Selectatec Compatible Vaporizer
Selectatec compatible vaporizers, (e.g. the
Delta with the Selectatec connector block),
may be mounted on a universal back bar
manifold.
Two- and three-station manifolds are
available, with each station fitted with two
valve capsule assemblies for vaporizer
connector block attachment.
When a vaporizer is installed on a station the
valves on that station open automatically to
allow gas flow into and out of the vaporizer.
Removal of the vaporizer from the station
closes the valves on that station.
Selectatec compatible vaporizer interlock
systems are described in the literature
supplied with the vaporizer.
The outlet (1) can be located at the front or
rear of the machine, and has a 22 mm male
taper and concentric 15 mm female taper.
The male taper incorporates the Penlon
Safelock system designed to prevent
accidental disconnection of the breathing
system.

Oxygen Flush
An emergency oxygen flush valve button (2)
is mounted at the font of the machine and is
marked ‘O
Depressing the button provides a delivery of
between 35-75 litres/min of oxygen through
the common gas outlet (1).
Releasing the button allows the springloaded valve to return to its normal position.

Check for a flow of air when the flowmeter
needle valve is operated.
CAUTION
The mechanical AHD system
requires that the oxygen flowmeter
control is restricted to prevent the
needle valve from fully closing.
This ensures a minimum oxygen
basal flow.
DO NOT attempt to close the flow
to zero.
Do not overtighten the knob.
1
5.2.2 Gas Cylinder Supplies
CAUTION
Open the cylinder valves slowly to avoid damage to the
pressure reducing valve and pressure gauges. Ensure
that valves are at least one full turn open when in use.
1. Fit the gas cylinders to their respective
yokes, open the cylinder valves one at a
time and check the pressure on each gauge.
NOTE
a) When two cylinders are provided for a single gas,
test each separately, clearing pressure after each
test by opening the flowmeter valve.
b) Turn off the reserve cylinders during normal use.
c) N

PRE-USE CHECKS
5.3 Vaporizers
5.3.1 Pre-use Checks
On ALL vaporizers, before use:
1. Check all joints for gas tightness.
2. Check vaporizer agent level.
3. Check for correct agent delivery
concentrations - use an agent analyser.
Always follow the procedures and checklist
given in the instruction manual supplied with
the vaporizer, particularly when filling the
vaporizer with anaesthetic agent.
5.3.2 General Information
WARNING
Vaporizers must always be mounted, never
used free-standing.
Free standing vaporizers may be accidentally
tipped resulting in excessive and uncalibrated
volumes of anaesthetic drug entering the
breathing system.
Do not install or connect any vaporizer of any
description between the CGO and the
breathing system, unless it is specifically
designed for such use. (This allows the
oxygen flush flow to pass through the
vaporizer, and severe overdosage may result).
5.3.4 Selectatec Compatible
Vaporizers with Interlock
WARNING
Only vaporizers with the Selectatec
compatible interlock function will interlock if
installed on a two station or three station
manifold.
The installation of non-interlock vaporizers
allows the possible operation of more than
one vaporizer at the same time.
If two vaporizers only are mounted on a three
station manifold, they must be installed on
adjacent stations (i.e. the middle station must
be occupied).
Check that the interlock mechanisms of all
the vaporizers on the manifold are working
correctly, i.e. check that only one vaporizer
at a time can be turned on.
5.3.5 Cagemount Vaporizer
Some international standards demand that
this type of vaporizer should only be used on
machines with a single mounting station.
In addition, use safety clip (Cat. No. 52275)
to retain the cagemount taper cones in position on the vaporizer.
5.3.3 Selectatec Mounting System
Up to two Selectatec compatible vaporizers
may be fitted (up to three on SP3 models).
To install the vaporizer:
a) Carefully offer the vaporizer up to the
manifold.
b) Check that the gas connection ports on
the vaporizer are aligned with the valves
on the manifold.
c) Carefully lower the vaporizer onto the
manifold and lock the vaporizer into
position by clockwise rotation of the
locking lever through 90o.
NOTE Do not use excessive force to lock
the vaporizer onto the manifold. Damage to
the locking fastener will result.
CAUTION
To prevent damage to the locking shaft, ensure
that the gas connection ports are aligned with the
valves on the manifold, and are correctly
engaged, before tightening the locking lever.
