FUNCTION DESCRIPTION (continued)
The flow control valves are used to adjust the O2 and N2O flows.
Restrictors located at the outlets of the SORC generate back-pressures. These
back-pressures exert a force on the control diaphragms of the SORC. The O2
back-pressure opens the SORC. The N 2O back-pressure closes the SORC. The
pressure ratio at the control diaphragm affects the N2O flow.
The restrictors and the spring tension are dimensioned such that a minimum
concentration of 23 vol.% O2 is always ensured. The maximum O 2 flow is
approx. 12 L/min.

valve) has a selector which can be used to toggle between "MAN" and "SPONT".
In the "MAN" position, the compact

This position is used for manual ventilation of the patient. The APL valve
opening pressure can be adjusted from 5 to 70 cmH2O.
In the "SPONT" position the APL valve is open to atmosphere. This position is
used for spontaneous breathing.
The pressure limit (Pmax) can also be adjusted (through front panel interface)
during volume control from 15 cmH2O to 70 cmH2O using the control box and
the PEEP Pmax valve.

Manual Ventilation: General
During manual ventilation, the APL valve is set to the "MAN" position.
The patient system safety valve is activated. The piston of the ventilator
is in the upper end position in order to reduce the volume of the
ventilator.
Manual Ventilation: Inspiration
During inspiration, expiratory valve remains closed. When the clinician
compresses the breathing bag the gas mixture (expiratory gas and fresh
gas) flows through the fresh-gas decoupling valve, the inspiratory valve,
the O2 sensor, the inspiratory hose, and the Y-piece into the patient’s
lung. The pressure sensor measures the airway pressure. The APL valve
limits the ventilation pressure. Any excess amount of the gas mixture
flows through the APL valve and the non-return valve to the anesthetic
gas scavenging system.

Spontaneous Breathing: General
A prerequisite for spontaneous
spontaneous breathing is that the pat
patient
ient is supplied
with a sufficient amount of fresh gas. The APL valve selector must be set
to the "SPONT" position. No pressure builds up in the compact breathing
system.
Spontaneous Breathing: Inspiration
During inspiration, the expiratory valve remains closed thus preventing
rebreathing of expiratory gas containing CO2.
The patient inhales the gas mixture
mi xture (expiratory gas and fresh gas) from
the breathing bag. The gas mixture flows through the fresh-gas
decoupling valve, the inspiratory valve, the O2 sensor, the inspiratory
hose, and through the Y-piece into the lung. The pressure sensor
measures the airway pressure.

Volume Control Mode: General
A prerequisite for volume control
control is that the patient is supplied with a
sufficient amount of fresh gas.
The APL bypass valve opens in volume mode, allowing excess gas to be
vented to the scavenging system regardless of the MAN-SPONT valve
setting.
The safety valve of the patient system makes sure that no pressures
greater than 75 cmH2O build up in the system.
During ventilation, the pressure limit (Pmax) can be adjusted at the user
interface.

FUNCTION DESCRIPTION (continued)
Volume/Pressure Control Mode: Inspiration
During inspiration, the PEEP/Pmax valve remains closed. The control pressure
present at the PEEP/Pmax valve varies with the set pressure limit (Pmax).
The pressure generated by the ventilator’s piston closes the fresh-gas
fr esh-gas
decoupling valve. The gas mixture (expiratory gas and fresh gas) flows through
the inspiratory valve, the O2 sensor, the inspiratory hose, and through the Ypiece into the lung. The pressure sensor measures the airway pressure. The
ventilation pressure cannot exceed the pressure limit (Pmax) set on the control
box because the PEEP/Pmax valve opens. The fresh gas then fills
fi lls the breathing
bag.
Any excess fresh gas flows through the open APL bypass valve, and through
through the
non-return valve into the anesthetic gas scavenging system.

The ventilator pressure transducer is the same type as the one used for
measuring airway pressure. A hose connects the transducer’s

port to a hose barb located on the top cover of the ventilator. The purpose of this
transducer is to allow the software to sense when a condition exists that would
cause the ventilator negative pressure relief valve to open. The threshold used
by the software for this condition is indicated in the table below. In normal use
the primary cause for this condition is an insufficient amount of reserve gas in
the breathing bag. The operator is alerted when this condition exists, with a
medium priority “FRESH GAS LOW” alarm. This alarm

When the Fabius GS is operating in the automatic mode, the pump on
the pneumatic assembly is running, and the electronic PEEP valve
receives a signal from the main control PCB. The amount of current
supplied to the coil of the electronic PEEP valve is proportional to the
PEEP value set by the operator
operator,, and controls the position of the
diaphragm within the electronic PEEP valve. This then determines the
control pressure applied to the proportional PEEP valve in the breathing
system, which maintains the desired amount of PEEP during patient
expiration. The V1 reservoir smooths out pressure variations caused by
the pump. See Figure 2-21.

FiO2 Measur
Measureme
ement
nt
The O2 sensor measures the fraction of inspired O 2 (FiO2) in the respiratory gas.
The O2 sensor contains an alkaline electrolyte, a lead anode, two gold cathodes,
and a Teflon membrane. The spatial separation of the two gold cathodes allows
a voltage comparison to be made as explained below.
The O2 sensor is an electrochemical cell that generates a voltage from the ion
current.

sensor
or
The O2 to be measured diffuses through the Teflon
Teflon membrane, reacts at the gold
cathodes (negative polarity) and forms lead oxide and water at the lead anode
(positive polarity). During this chemical process, a voltage is generated which is
proportional to the O2 partial pressure.
The internal resistance of the cell is determined by the surface area of the gold
cathodes, the O2 diffusion velocity, the distance between the gold cathodes and
the lead anode. This resistance is approximately 700 ohms.
The chemical process is temperature-sensitive. Therefore temperature-sensitive
resistors are connected in parallel with the O2 sensor. These resistors and the
internal resistance of the O2 sensor correct the measuring voltage. Because two
cathodes used in the O 2 sensor cell, two different voltages are generated. These
voltages are compared with each other.
other. If their difference exceeds a certain
value, the machine prompts the operator to check the cell.
If
the O2 sensor fails, the control box will indicate an error on the graphics
display.

2.14 Respirator
Respiratory
y Flow
Flow Measur
Measurement
ement
The flow sensor functions according to the constant temperature hot-wire
anemometer principle. Respiratory gas flows past a thin platinum wire. This
platinum wire (A) is located in a measuring tube and is electrically heated. The
platinum wire is held at a constant temperature. Gas flow removes heat from
the hot wire. The higher the gas flow rate, the greater the heat removal. The
amount of electrical current needed to maintain a constant platinum wire
temperature is thus proportional to the gas flow rate.
A second platinum wire (B) in the measuring tube is used
used to compensate for
interferences from different gases present in the respiratory gas. The heat
removed from the second platinum wire is measured during inspiration when
the gas flow is zero.
The different gases present in the respiratory gas have a different thermal
conductivity.. The amount of heat removed from the second platinum wire is
conductivity
thus an indicator of respiratory gas composition.
Internal calibration tables for O2/N2O mixtures, Air and 100% O2 are used to
linearize the measured flow.

2.15 Gas Flow Rate Measuremen
Measurementt
The gas flow sensors operate on the principle of specific heat for individual
gases. In each sensor, as the gas flows through a heated chamber the gas
molecules carry away a certain amount of heat relative to the specific heat index
for that gas.
A known amount of electrical current is required to maintain
maintain the temperature
in the heated chamber. The higher the gas flow rate, the more heat is removed
from the chamber and more current is required to maintain the temperature in
the chamber.
chamber. This current is then scaled and displayed as liters per minute flow
rate for each gas.
