2.1 Theory overview
This section describes:
• The f1 0w of gas through the anesthesia machine.
• The flow of gas through the breathing system.
• Elect时 cal signals between the anesthesia machine, includingthe breathing
system , and the ventilator.
2.2 Gas flow through the anesthesia machine
2.2.10verview
Gas supplies
Referto Figure 2- 1.
Gas comes into the system through a pipeline (2) or cylinder (4) connection.
AII connections have indexed fittings, filters , and check valves (one-way
valves). Gauges show the pipeline (1) and cylinder (3) pre臼ures.
A primary regulator (5) decreases the cylinder pressu 陀s to approximately
pipeline levels. A pressu 陀 relief valve (6) helps protect the system from high
pressures.
To help prevent problems with the gas supplies:
• Install yoke plugs on all empty cylinder connections.
• When a pipeline supply is adequate, keep the cylinder valve closed.
O2 flow
Pipeline or regulated cylinder pressure supplies O2 directly to the ventilator
(7a for O2 drive gas) and the venturi suction (21a for O2 drive gas) supply
connection. An additional regulator (13) decreases the pre臼ure for the flush
valve (14a) and the auxiliary flowmeter (25).
The f1 ush valve supplies high flows of O2 to the fresh gas outlet (26 or 27)
when you push the flush button. The flush p陀ssure switch (14b) monitors
activation ofthe flush valve.
When the system switch (8) is On, O2 flows to the rest of the system.
Asecondary regulaωr (10) supplies a constant O2 pressureωthe O2 flow
control valve (11). Th ere is a minimum flow of 25 to 75 mνmin (for dual-tube
flowmeters) or 175ω225mνmin (for single-tube f1 owmeters) through the
O2 flowmeter(12).
Th e O2 pressure switch (9) monitors the O2 supply pressure. If the pressure is
too low, an alarm appears on the ventilator display.
2-2
07/ 04 1009.0356'{)00
2 Th eory of Operation
Air and N20 flow
Pipeline or 陀gulated cylinder pressure supplies Air directJ y to the ventilator
(7b for Air drive gas) and the venturi suction (21b for Air drive gas) supply
connection.
When the system switch (8) is On , air flows to the rest of the system.
Asecondary 陀gulator (18) supplies the Airflow control valve (19). Because
there is no balance regulator, air flow continues at the set rate during an O2
supply failure.
A balance regulator(15) controls the N20 supply pressureωthe N20flow
control valve(16). The O2 secondary regulator pre臼ure at a pilot port controls
the output ofthe balance regulator. The N20 output pressure drops with
decreasing O2 supply pressure and shuts off hypoxic gas flow before the O2
supply pressure reaches zero.
A chain link system (Unk-25) on the N20 and O2 flow controls (16, 11) helps
keep the O2 concentration higherthan 21% (approximate value) at the
common gas outlet.
Mixed gas
Th e mixed gas goes from the flowmeter outlet, through the vaporizer manifold
and vaporizer (23) that is On , to the ACGO selector switch (E). A pressure relief
valve (24) sets the maximum outlet pressure.
The ACGO selector switch directs the mixed gas to the selected circuit - to the
breathingsystem (26) orto the ACGO (27).

2.2.3 Suction regulators
Pipeline vacuum
The suction regulator (shown in Figure 2-2) uses an external vacuum source.
Venturi Drive vacuum
Th e suction regulator (shown in Figure 2-3) uses an internal , venturi derived
vacuum source.
Drive gas (internally plumbed Air or O2) enters the Venturi Module (VM) at the
drive po同 (A) . As the drive gas pa臼es through the venturi module , a vacuum
is created at port B. The drive gas exits the venturi module at port C and is
exhausted outside the machine through the muffler (D).
Th e control p。此(日 on the venturi module 陀sponds to pneumatic signals from
the front panel switch on the Suction Control Module (SCM) to turn the venturi
vacuum drive gas on or off. 刊 e check valve (C的 helps prevent pressurization
of the suction circuitry ifthe exhaust is occluded or the venturi unit fails.

• Stops O2 and Airto the flowhead (pneumatic).
• Without O2 pressure, the N2 0 balance regulator stops N2 0.
In the On position
The switch:
• Tums on the ventilaωr (elect时 cal).
• Supplies O2 and Air to the flowhead.
• With adequate O2 pressure, the N2 0 balance regulatorsupplies N2 0.

2.2.5 Flow control
.&.
WARNING
Needle valves (one for each gas) adjust gas flows. Clockwise rotation
decreases flow. Counterclockwise increases flow. Mechanical stops set
minimum flows for all gases. The link system sets the maximum ratio of N2 0 to
O2 ,
The Li nk 25 Proportioning System sets a minimum O2 concentration in
the fresh gas stream when only O2 and N2 0 are used. Use of an absorber
or another gas can still cause a hypoxic mixtu 陀 to be delivered to the
patient, especially at low O2 flow rates.
Minimum flows
At minimum flow, two tabs p陀vent clockwise rotation of the valve stem. One
tab is on the stop collar; the other is on the valve body.
Stop Tabs
Valve Body
\三~
Valve
Stem
Link system
The chain link system helps assure an approximate minimum 1 to 3 ratio of
flow between O2 and N2 0. When engaged (minimum O2 concentration), a tab
on the O2 knob is in contact with a tab on the O2 sprocket so that the O2 and
N20 knobs turn together:
• an increase in N2 0 flow causes an increase in O2 f1 ow,
• a decrease in O2 f1 0w causes a decrease in N20 flow.

1009-0 356-000 07/04

S/5 Aespire
Higher concentrations of O2 are possible when the link system is not engaged:
eitherby 陀ducing the N2 0 flow below the point of engagement or by
inc陀asing O2 flow above the point of engagement.
When the N20 flow is below the point of engagement, increasing the N2 0 flow
turns the O2 sprocket without changing the O2 flow. At the point of
engagement, the tab on the O2 sprocket makes contact with the tab on the O2
knob. Once the linkage is engaged , turning the N2 0 flow control
counterclockwise (increase in N20 flow) also turns the O2 knob
counterclockwise (increase in O2 flow) to maintain a nominal25% minimum
O2 concentration.
Decreasing the N2 0 flow from the engagement point rotates the tab on the O2
sprocket away from the tab on the O2 knob. Increasing the O2 flow rotates the
knob tab away from the sprocket tab. Either action increases the O2
concentration above 21 %. Sufficiently decreasing O2 flow or increasing the
N2 0 flow brings the two tabs back into contact and engages the linkage.

range of400ω700mνmin) and then install the sprockets with the O2
knobjsprocket engaged.
Maximum flows
AII gas flows in Canada require maximum flow stopS. A maximum stop collar
on the body of the needle valve and a stop collar on the stem of the needle
valve set the maximum flow.
At maximum f1 ow, a tab on the stop collar hits the tab on the maximum stop
collar and prevents you from turning the knob further counterclockwise. As
you decrease the flow , the valve stem moves towa 叫 the needle valve
assembly and clears the tab.

2.3 Flow through the breathing system
2.3.1 Overview of flow
paths
This section looks at three types offlow paths.
• Ventilation pa伽s: How gas flows from the drive source (bag or bellows) to
and from the patient.
• Fresh gas paths: Fresh gas can flow from the machine interface directly to
the patient through the inspiratory check valve, orthrough the abso巾er into
the expiratory flow , or directly to an external circuit through the optional
auxiliary common gas outlet.
• Scavenged gas paths: APL or Pop-o仔.

7.2 Breathing System Leak Test Guide
Note
Always perform the low-pressure leak test (Section 3.5) on the machine
before proceeding with these breathing system leak tests.
The procedure in Section 7.2.1 helps you isolate the leak: to Bag Mode
components, to Vent Mode components, or to components that are common
to both modes.
• If you have a similar leak in both the bag mode and the ventilator mode, you
must consider the Flow Sensor Module, the Circuit Module, the Absorber
Canister area, and the bulkhead components (including CGO tubing).
Carefully inspect the circuit module for damaged seals or misassembly, and
the seating of the O2 sensor.
• If you have a larger leak in one area than the other (Vent or Bag), the leak is
most likely NOT in the Flow Sensor Module, the Circuit Module, the Absorber
Canister area , orthe bulkhead po忧s.
Follow the troubleshooting flowcharts in Section 7.2.2 to determine the best
sequence of tests for locating a breathing system leak.
Th e procedures in Section 7.2.3 test specific components ofthe b陀athing
system for leaks.
.&. WARNING
Objects in the breathingsystem can stop gas flowto the patien t. This can
cause injury or death:
Do not use a test plug that is small enough to fall into the breathing
system.
Make sure thatthere are no test plugs or other objects caught in the
breathing system.
