Warnings, cautions, and notes

Please take the time to familiarize yourself with the following safety
considerations, special handling requirements, and regulations that govern the use
of the 700 Series Ventilator System.

Warning

To avoid an electrical shock hazard while servicing the ventilator, be
sure to remove all power to the ventilator by disconnecting the power
source and turning off all ventilator power switches.

Warning

To avoid a fire hazard, keep matches, lighted cigarettes, and all other
sources of ignition (e.g., flammable anesthetics and/or heaters) away
from the ventilator and oxygen hoses.

Do not use oxygen hoses that are worn, frayed, or contaminated by
combustible materials such as grease or oils. (Textiles, oils, and other
combustibles are easily ignited and burn with great intensity in air
enriched with oxygen.)

In case of fire or a burning smell, immediately disconnect the ventilator
from the oxygen supply and electrical power source.

Electromagnetic susceptibility

The 700 Series Ventilator System complies with the requirements of IEC 60601­1-2 (EMC Collateral Standard), which includes E-field susceptibility and ESD
requirements. However, even though the device is compliant at the levels of
immunity specified in the standard, certain transmitting devices (cellular phones,
walkie-talkies, cordless phones, paging transmitters, etc.) emit radio frequencies
that could interrupt ventilator operation if located in a range too close to the
ventilator. It is difficult to determine when the field strength of these devices
becomes excessive. Practitioners should be aware that radio frequency emissions
are additive, and that the ventilator must be located a sufficient distance from
transmitting devices to avoid interruption. Do not operate the ventilator in a
magnetic resonance imaging (MRI) environment. The Alarm handling section of
this manual describes possible ventilator alarms and what to do if they occur.
Consult with your institution’s biomedical engineering department in case of
interrupted ventilator operation, and before relocating any life support equipment.

..............................................................................

The 700 Series Ventilator System (including the 740 and 760 Ventilators)
provides respiratory support for a wide range of pediatric to adult patients for a
wide variety of clinical conditions. The ventilator’s mixing technique allows it to
ventilate critically ill patients at adjustable oxygen concentrations without the
need for a blender, compressor, or hospital-grade wall air.

The 700 Series Ventilator System can be mains- or battery-powered. Each
ventilator includes two microcontrollers: one for breath delivery (which controls
ventilation), and one for the user interface (which monitors ventilator and patient
data). Each microcontroller verifies that the other is functioning properly. Using
two independent microcontrollers in this fashion prevents a single fault from
causing a simultaneous failure of controlling and monitoring functions.

The 700 Series Ventilator System supplies mandatory or spontaneous breaths
with a piston-based pneumatic system. Table 1-1 summarizes the modes and
breath types offered by the 740 and 760 Ventilators. Mandatory breaths can be

volume control ventilation (VCV, available on 740 and 760 Ventilators) or
pressure control ventilation (PCV, available on the 760 Ventilator only). VCV

delivers breaths to the patient at a preset tidal volume, peak flow, waveform, and
oxygen concentration at a minimum respiratory rate. PCV delivers breaths to the
patient at a preset inspiratory pressure, I:E ratio or inspiratory time, rise time
factor (how quickly inspiratory pressure rises to achieve the set inspiratory
pressure), and oxygen concentration at a minimum respiratory rate. A
spontaneous breath allows the patient inspiratory flows of up to 300 L/min, with
or without pressure support ventilation (PSV). On the 760 Ventilator, you can set
the rise time factor and exhalation flow sensitivity (that is, the point at which the
ventilator cycles from inspiration to exhalation) in PSV.

The ventilator begins apnea ventilation if no breath (patient- , ventilator-, or
operator-initiated) is delivered within the selected apnea interval. Apnea
ventilation is active during all modes. On the 740 Ventilator, only VCV breaths
are available in apnea ventilation. On the 760 Ventilator, VCV or PCV breaths are
available in apnea ventilation.

The 760 Ventilator also offers the ability to perform respiratory mechanics
calculations and maneuvers as a standard feature using the EXP PAUSE (to

This manual tells you how to operate and perform simple maintenance for the 700
Series Ventilator. Mallinckrodt recommends that you become familiar with this

manual and accompanying labels before attempting to operate or maintain the
ventilator. If you need additional copies of this manual, contact your Mallinckrodt
representative.

To ensure optimum performance of the 700 Series Ventilator System,
Mallinckrodt recommends that a qualified service technician perform periodic
maintenance on the ventilator. For more information, contact your Mallinckrodt
representative.

1.1 Functional description

By pressing keys and turning the knob on the ventilator keyboard, the operator
gives initial instructions and data to the ventilator
(Figure 1-1). The user interface microcontroller processes this information and

...............................................................................

stores it in the ventilator’s memory. The breath delivery microcontroller uses this
stored information to control and monitor the flow of gas to and from the patient.

The 700 Series Ventilator uses a flow trigger to recognize patient effort. The
trigger monitors flow from the piston during exhalation. When the patient
inhales, patient circuit pressure drops very slightly below end-expiratory
pressure. At the same time, the piston moves forward to deliver flow to the
ventilator breathing circuit and maintain the preset PEEP/CPAP level. The level
of flow depends on the patient’s effort. If this flow exceeds the user-set level, the
ventilator triggers. By design, the ventilator attempts to maintain PEEP in the
presence of a circuit leak. Since a leak drives the piston to deliver flow to make
up for pressure losses, a circuit leak can require an increase in the flow trigger
level to avoid autocycling.

During exhalation, the ventilator’s piston retracts and draws air and oxygen into
the cylinder. The ventilator uses room air, which means the ventilator can operate
without a compressor or wall air source. Room air enters the ventilator through a
protected user-replaceable air intake filter just inside the ventilator cabinet. This
filter captures airborne particles.

Oxygen from a cylinder or wall supply enters the ventilator through a hose and
oxygen fitting (the fitting is available in several versions). Once inside the
ventilator, the oxygen is regulated to a pressure the ventilator can use, then mixed
with air, according to the selected % O

The flow-triggered piston/cylinder system and motor controller circuit control the
flow of gas to the patient. On the 760 Ventilator in PCV or PSV, the rate of flow
is also determined by the preset rise time factor. This system is designed with a
minute gap (about the size of a thin sheet of paper) between the piston and the
cylinder wall. This design eliminates the friction between the piston and cylinder,
allowing it to respond more rapidly than a “sealed” system.

.

A small amount of gas leaks through the gap between the piston and cylinder.
Ventilator software and a continuous forward motion of the piston compensate for
this leak.

The piston delivers the mixed air and oxygen through the inspiratory manifold
system, and out to the patient. The oxygen concentration and temperature of the
delivered gas are monitored here, using a galvanic oxygen sensor and a
thermistor. The galvanic sensor generates a voltage proportional to the partial
pressure of oxygen, from which the oxygen concentration is calculated. The
ventilator alarms if the monitored oxygen concentration is more than ten
percentage points above or below the % O

setting. The inspiratory manifold

system also includes a safety valve to relieve patient pressure if necessary (for
example, if the ventilator breathing circuit is kinked or occluded).

The patient system includes the components external to the ventilator that route
gas between the ventilator and the patient. These components include the
inspiratory filter (which protects against contamination between the ventilator
and patient), a humidification device, ventilator breathing circuit (the tubing
through which the gas travels), collector vial (which protects the exhalation
system from moisture in the exhaled gas, and can be emptied without losing
circuit PEEP), and an expiratory filter (which limits the bacteria in the patient’s
exhaled gas from escaping to room air or contaminating the ventilator).

1 Introduction

The heated exhalation system monitors the flow of the patient’s exhaled gas using
a differential pressure transducer. The patient exhales through the exhalation
valve. During exhalation, the PEEP/CPAP system maintains user-selected
pressure in the ventilator breathing circuit.

Throughout the respiratory cycle, pressure transducers monitor inspiratory,
expiratory, and atmospheric pressures. The temperatures of the pneumatic
compartment and inspiratory gas are also monitored. Information from these
transducers is continuously used to update the calculations that control
ventilation. (Appendix F provides a diagram of the ventilator’s pneumatic system
and ventilator breathing circuit.)

Power to operate the ventilator comes from ac mains (wall) or battery power. The
power supply is designed to protect against excessive voltages, temperatures, or
current draws. A power cord retainer prevents the cord from accidental
disconnection.

The ventilator includes an internal battery, and accommodates an optional
external battery. Depending on the ventilator settings, battery backup power can
be supplied for up to 2 ½
the external battery. Both batteries are recharged during operation from ac power.
If both are installed, the external battery is used first when ac power is not
present. If the external battery is depleted or not installed, the internal battery
supplies power to the ventilator when ac power is not available. The keyboard
indicates the source of power and battery charge level of the internal battery at all
times.

Emergency modes: The ventilator declares a ventilator inoperative (VENT INOP)
condition if a hardware failure or critical software error that could compromise

safe ventilation occurs. In case of a ventilator inoperative condition, the VENT
INOP indicator lights and the ventilator enters the safety valve open (SVO) state.
To correct a ventilator inoperative condition, the ventilator must be turned off,
then powered on again; at power-on, the operator must run extended self-test
(EST). The ventilator must pass EST before normal ventilation can resume.

The safety valve allows the patient to breathe room air unassisted when the
ventilator is in the SVO state. The ventilator remains in the SVO state until
power-on self-test (POST) verifies that power levels to the ventilator are
acceptable and that the motor controller and microcontrollers are functioning
correctly, and until the user has confirmed ventilator settings.

If the ventilator enters the SVO state and POST is not running, the SAFETY
VALVE OPEN indicator lights and a high-priority alarm sounds. The ventilator
enters the SVO state if it detects a hardware or software failure that could

compromise safe ventilation. In case of a malfunction that prevents software from
opening the safety valve, there is also an analog circuit that opens the safety valve
when system pressure exceeds 115 cmH

If the ventilator detects an occlusion or a continuous high inspiratory pressure
condition, it opens the safety and exhalation valves to vent excess pressure, then
shuts them and begins occlusion cycling mode. In occlusion cycling mode the
ventilator uses current settings except for those summarized in Table 1-2. If the
ventilator again detects an occlusion or continuous high pressure condition, it
again opens the safety and exhalation valves then resumes occlusion cycling
mode. If the operator presses the alarm reset key or the ventilator does not detect
an occlusion or continuous high pressure condition, it reverts to normal
ventilation using the most recently accepted settings.

The VENTILATOR SETTINGS section of the keyboard allows you to select the
ventilation mode, breath type, and settings. For more detail on ventilation modes
and breath delivery, see Appendix D.

To change the mode and settings, select the mode, then the breath type, and then
the ventilator settings. The keys flash during setup and mode changes to ensure
that you review all pertinent settings. The keyboard is designed to minimize
accidental or unintentional changes.

Table 1-3 summarizes the functions of the keys, knob, and indicators in the
VENTILATOR SETTINGS section of the keyboard. Ventilator settings are also
limited by these breath delivery boundaries:

• I:E ratio £ 4:1 for PCV (760 Ventilator only), £ 3:1 for all other breath types

• Inspiratory time = 0.2 to 8 seconds (excluding plateau)

• Expiratory time ³ 0.2 seconds

EXP PAUSE
(760 only)

Allows you to measure the patient’s auto-PEEP. An EXP PAUSE
maneuver causes the ventilator to close the exhalation valve at the end
of the expiratory phase, and not deliver the next mandatory breath. At
the end of the maneuver, the message window shows the calculated
value for auto-PEEP (expiratory pressure at the beginning of the
maneuver minus expiratory pressure at the end of the maneuver) and
total PEEP for 30 seconds.

The message window shows the end expiratory flow in L/min at the
beginning of each breath. If there is expiratory flow when the ventilator
delivers the next breath, auto-PEEP is present.

The EXP PAUSE continues as long as you hold down the key, and
should last only until expirator y pressure stabilizes. An EXP PAUSE
maneuver ends when you release the key, the patient initiates a breath,
an alarm occurs, the expiratory phase (including the maneuver) lasts
more than 20 seconds, or the ventilator detects a leak.

INSP PAUSE
(760 only)

Allows you to measure the patient’s compliance and resistance. An
extended inspiratory pause also allows you to expand the patient’s lungs
forupto10seconds.

Pressing INSP PAUSE momentarily causes the ventilator to wait until
the end of the inspiratory phase of the current or next mandatory breath
(in SPONT mode, the ventilator delivers a mandatory breath using the
MANUAL INSP key according to the apnea settings), stop breath
delivery, and keep the exhalation valve closed. The INSP PAUSE
continues until the ventilator detects a stable plateau pressure or 2
seconds have elapsed. An INSP PAUSE maneuver ends when a stable
plateau is reached or an alarm occurs.

Pressing INSP PAUSE for 2 or more seconds after the pause begins
causes the ventilator to deliver an inspiratory pause for as long as you
hold down the key. An extended INSP PAUSE maneuver ends when you
release the key or 10 seconds have elapsed.

You can press CLEAR or release the INSP PAUSE key at any time to
cancel an INSP PAUSE maneuver, and alarms cancel the maneuver.

This section tells you how to set up the ventilator, including:

• Connecting and using the internal and external batteries

• Connecting the electrical supply

• Connecting the oxygen supply

• Connecting the ventilator breathing circuit

• Installing the collector vial

• Installing the flex arm

• Installing the humidifier

• Using the ventilator cart

Warning

• To avoid tipping or damaging the ventilator, do not stack other
equipment on the ventilator. 700 Series Ventilators are designed
to be mounted on either a cart or a shelf by a qualified service
technician. When lifting the ventilator, lift from the base, and use
assistance and appropriate safety precautions. Figure 2-1 shows
proper lifting technique.

• To avoid the possibility of injury to the patient and to ensure
proper ventilator operation, do not attach any device to the port
labeled “EXHAUST” unless the device is specifically authorized
by Mallinckrodt.

• To minimize the increased risk of fire due to an oxygen-enriched
environment, do not use the ventilator in a hyperbaric chamber.

• To avoid raising the oxygen concentration of room air, use the
ventilator in an adequately ventilated room.

2.1 Connecting and using internal and external batteries

Warning

A Mallinckrodt battery must always be installed in the ventilator.
Without a battery, the ventilator is not protected against low or lost
ac power. Do not use the ventilator unless a battery with at least
minimal charge is installed.

2-2

NOTE:

If the ventilator has been stored for an extended period, allow it to
acclimate to its environment before turning it on. This helps ensure
that the ventilator powers up correctly.

Every 700 Series Ventilator System includes an internal battery as a backup
power supply that comes standard with the ventilator. The internal battery can
provide up to 2

½ hours of backup power, depending on ventilator settings and

battery charge level. The ventilator operates on backup power when ac power is
lost or drops below minimum. The internal battery’s charge level is continuously

Figure 2-2. Internal battery charge indicator

The optional external battery supplies up to 7 additional hours of backup power in
case ac power is lost or falls below minimum. (See Appendix B for external
battery ordering information.) If installed, the external battery is the first source
of backup power. The ventilator uses the internal battery if the external battery is
depleted or is not connected.

NOTE:

When the ventilator switches off because battery charge is
inadequate, turn off the power switch to prevent the battery from
being fully depleted. Connect the ventilator to ac power as soon as
possible.

The ventilator charges the internal and external batteries during ac power
operation, or in standby mode when attached to ac power. (See Appendix C for
battery specifications.) When the ventilator is operating on battery, you can use
the MENU key to check the estimated operational time remaining until recharge
is required for the internal and external batteries. (Section 6 tells you how to use
the MENU key.) The ventilator must operate for 2 minutes before it can estimate
battery time remaining.

You can disconnect and connect the external battery during normal operation.
When operating the ventilator on battery power, you can install the external

battery on the cart for easy transport. Follow these steps to connect the external
battery:

1. Mount the external battery on the base of the cart (or other suitable
location).

2. Plug the external battery’s cable into the connector (Figure 2-3).

3. Figure 2-4 shows you how to disconnect the external battery.

To ensure that the batteries retain their charge, store the ventilator in standby
mode, with its power switch on, and connected to ac power. If the ventilator is not
stored in this manner, check battery charge levels before using the ventilator.

Caution

If you plan to store the ventilator for more than 6 months, remove
batteries before storage. Replace the internal battery before using
the ventilator again. A qualified service technician must replace the
battery according to the instructions in the 700 Series Ventilator
System Service Manual.

If you turn on the ventilator after it has been unplugged for an extended period,
the LOW EXT BATTERY and LOW INT BATTERY alarms may become active.
If so, recharge the internal battery by leaving the ventilator plugged in and turned
on in standby mode (with no patient connected) for up to 8 hours.

2-4

If the LOW EXT BATTERY, LOW INT BATTERY, or BAT NOT CHARGING
alarm is still active after 8 hours, replace the batteries. If you turn off the
ventilator when the battery is absent or inadequately charged, a LOSS OF
POWER alarm sounds for at least 2 minutes.

NOTE:

The ON BATTERY indicator flashes when the ventilator is operating
on battery power.

Warning

• To avoid electrical shock hazard, connect the ventilator power
cord into a grounded ac power outlet. If the integrity of the ac
ground is in question, operate the ventilator from the internal or
external battery.

• If used in the U.S., connect the ventilator to an ac receptacle
marked “Hospital Only” or “Hospital Grade” to ensure grounding
reliability.

2-6

Every 700 Series Ventilator System is supplied with a power cord. A power cord
retainer covers the connector and socket to protect against liquid spills or
accidental disconnection.

When the ventilator is ready for operation on ac power, connect the power cord to
ac power (see Figure 2-5).

2.3 Connecting the oxygen supply

Warning

• To ensure proper oxygen concentration, do not obstruct the
ventilator’s air intake.

• To ensure adequate oxygen delivery to the patient, use
Mallinckrodt-supplied oxygen hoses only. Use of other oxygen
hoses could result in inadequate or inappropriate oxygen
pressures or leaks at the oxygen inlet.

• When using a cylinder oxygen supply, point the cylinder's
pressure relief device away from the ventilator air intake. This
helps avoid creating an oxygen-rich environment within the
ventilator in the event that the cylinder oxygen regulator
malfunctions.

The 700 Series Ventilator System can use oxygen from a cylinder or wall supply.
Follow these steps to connect the oxygen supply:

1. Ensure that the oxygen supply pressure is between 40 and 90 psi (275 and
620 kPa) (50 psi (345 kPa) recommended).

2-8

Warning

Due to excessive restriction of certain hose assemblies (listed in
Table B-1), reduced FIO
pressures
levels, make sure that oxygen inlet pressure is ³ 50 psi (345 kPa)
when using these hose assemblies.

2. Connect the oxygen supply to the oxygen inlet connector on the side of the
ventilator (see Figure 2-7). Make sure ventilator is configured with
adapter(s) as required.

Caution

To prevent damage to the ventilator, ensure that the connection to
the oxygen supply is clean and unlubricated.

NOTE:

Whenever a pressurized oxygen source is connected to the ventilator,
the oxygen regulator has a maximum bleed rate of 3 L/min, even when
the ventilator is not in use. Always take this bleed rate into account
when calculating oxygen cylinder volume and duration. This is
especially important when using the ventilator and cart while
transporting patients who are being ventilated at above-ambient

levels.

2.4 Connecting the ventilator breathing circuit

Warning

• To minimize the risk of bacterial contamination or component
damage, inspiratory and expiratory filters must always be
handled with care and connected to the ventilator during use.

• Use of an external pneumatically powered nebulizer with a 700
Series Ventilator results in added flow to the ventilator breathing

circuit. This additional flow can affect delivered tidal volumes,
spirometry and spirometry alarms, delivered FIO
triggering. (However, the Mallinckrodt EasyNeb™ Nebulizer is
designed to deliver aerosol medications to the patient without
affecting ventilator performance or patient data.)

• To minimize the risk of patient injury, use only ventilator breathing
circuits qualified for use in oxygen-enriched environments with
700 Series Ventilators. Do not use antistatic or electrically
conductive tubing. To ensure a leak-tight connection, only use
connectors and tubes with ISO-standard cone and socket fittings
(or use adapters to connect barbed cuff fittings to ISO-standard
fittings).

• Use ventilator breathing circuits identified by Mallinckrodt for use
with 700 Series Ventilators or circuits that ensure that the
maximum resistance values specified in Table C-5 are not
exceeded. Using a circuit with a higher resistance does not
prevent the ventilator from ventilating as long as the ventilator
passes SST.

...............................................................................

NOTE:

• Mallinckrodt recommends that you run SST every 15 days,
between patients, and when you change the ventilator breathing
circuit. Mallinckrodt recognizes that the protocol for running SST
varies widely among healthcare institutions. It is not possible for
Mallinckrodt to specify or require specific practices that will meet
all needs, or to be responsible for the effectiveness of those
practices.

• Check the inspiratory and expiratory limbs of the ventilator
breathing circuit and the collector vial and in-line water traps
regularly for water buildup. Under certain conditions, they can fill
quickly. In case of a partial occlusion alarm, check for water in the
ventilator breathing circuit. In very severe cases, such a water
occlusion can potentially cause the ventilator to enter occlusion
cycling mode. Empty and clean the collector vial and in-line water
traps as necessary.

SECTION

Self tests (SST and EST) 4

..............................................................................

All 700 Series Ventilators include these built-in self tests:

• Short self test (SST) is a short (about 2 to 3 minutes) and simple sequence of

tests that verifies proper ventilator operation, checks the ventilator breathing
circuit for leaks, and measures the circuit compliance. Power on self test
(POST) is part of SST.

• Extended self test (EST) is a thorough test of the operational integrity of the

ventilator, both the electronics and the pneumatics. POST and SST are part of
EST.

Warning

• Before running SST or EST, you must disconnect the ventilator
from the patient. Running SST or EST while the ventilator is
connected to the patient can injure the patient.

• A fault identified in SST or EST indicates that the ventilator or an
associated component is defective. A defective ventilator or
associated component should be repaired before the ventilator is
returned to service, unless it can be determined with certainty
that the defect cannot create a hazard for the patient, or add to
the risks which may arise from other hazards.

Caution

To ensure accurate SST and EST operation, run SST and EST in
room air (% O
at least 10 minutes. (EST also requires an oxygen supply.)

Table 4-1 describes SST and EST.

Purpose When test is run

An abbreviated version of EST to be run
primarily by the operator. Makes detailed
checks of the pneumatics and electronics. It
also characterizes system leaks and system/
tubing compliance to compensate during
breath delivery. POST is run as part of SST.

Thoroughly tests the operational integrity of
the ventilator, both the electronics and
pneumatics. POST and SST are part of EST.

Before patient is connected
to the ventilator or after
ventilator breathing circuit or
humidifier is changed.

• When the ventilator
is serviced.

• As part of the ventilator
performance verification.

• Following a ventilator
inoperative.

NOTE:

The performance verification, described in the 700 Series Ventilator
System Service Manual, is a more thorough test of the ventilator to

verify specifications are met. The technician runs a partial or full
performance verification after servicing the ventilator and at regular
intervals.

Self tests (SST and EST) 4

...............................................................................

4.1 Short self test (SST)

Table 4-2 summarizes the functions of SST.

NOTE:

• Mallinckrodt recommends that you run SST every 15 days,
between patients, and when you change the ventilator breathing
circuit. Mallinckrodt recognizes that the protocol for running SST
varies widely among healthcare institutions. It is not possible for
Mallinckrodt to specify or require specific practices that will meet
all needs, or to be responsible for the effectiveness of those
practices.

• When SST asks you to do something (for example, press
ACCEPT or block the patient wye), the ventilator will wait
indefinitely for your response.

Follow these steps to run SST:

1. Turn on the ventilator. If ventilation has already begun, you must turn off
the ventilator, then turn it back on without starting ventilation. This allows
you access to the Self test menu function.

If you select the Self test function during ventilation the window displays
this message:

N/A in ventilation

2. Press MENU, turn the knob to select Self test, then press ACCEPT. The
usual 30-second timeout for your input is disabled during the entry to the
Self test function.

3. The window displays this message:

Shortselftest
Turn knob to view

4. Turn the knob to select Short self test (you can also select Extended self
test). The window displays this message:

4 Self tests (SST and EST)

If the ventilator has already been running for more than 10 minutes before
you select Short self test, this message is bypassed (see step 5). If the
ventilator was recently running and is already warmed up, you can press
CLEAR to override the Ve nt w ar min g message and begin SST. Mallinckrodt
cannot guarantee the accuracy of test results in this case, however.

5. The window displays this message:

Is pt disconnected?
ACCEPT to proceed

6. Press ACCEPT to confirm that no patient is connected to the ventilator. (Or
press CLEAR to back up through the menu.) The window displays this
message:

Block wye

7. Block the patient wye and then press ACCEPT.

8. The ventilator runs power-on self-test (POST) and displays this message for
a few seconds:

POST running...

Warning

If a single beep is not audible during POST, the main audible alarm
may be malfunctioning. Remove the ventilator from use and contact
service.

4-4

NOTE:

• If the ventilator is running on ac but the battery is low, upon
power up it may begin ventilating using the last valid settings and
an ABNORMAL RESTART alarm may occur.

• During POST it is recommended that you not switch off
ventilator power.

9. The message window then displays this message:

...............................................................................

where the humidification device type is the most recently selected type, as
follows:

• HME: Heat moisture exchanger (“artificial nose”)

• Dual heated wire: Humidifier with heated wire on expiratory limb, or on
both inspiratory and expiratory limbs

• No heated wire: Conventional humidifier without heated wire circuit on
the expiratory limb

Turn the knob to select the humidifier type attached, then press ACCEPT.

Warning

Incorrectly specifying the humidifier type during SST can affect the
accuracy of spirometry calculations.

10. The message window then displays this message:

tubing type

Choose tubing type

where the tubing type is the most recently selected ventilator breathing
circuit type.

Turn the knob to select the ventilator breathing circuit type (adult or
pediatric tubing) attached to the ventilator, then press ACCEPT.

Warning

Incorrectly specifying the ventilator breathing circuit type during
SST can cause an inappropriate sensitivity for the leak test and
occlusion alarm. Mallinckrodt recommends using pediatric circuits
when ventilating patients with 5-mm or smaller internal-diameter
artificial airways.

NOTE:

To ensure that compliance compensation functions correctly, you
must run SST with the circuit configured as intended for use on
the patient.

11. The message window then displays this message:

ET size: x.x mm
Choose ET size

Turn the knob to select the appropriate ET (endotracheal tube) size, then
press ACCEPT.

Warning

Specifying an ET tube size that is too large can cause premature
termination of breaths on very small pediatric patients. During
normal ventilation, you can use the MENU key’s User settings
function to change the ET tube size (see Section 6).

12. The ventilator automatically starts the test sequence. A message indicates
which test is being performed. Once started, a test cannot be interrupted. In
most cases you don’t need to do anything unless a test result is fault or fail,
or your action is required. When a test passes, SST automatically starts the
next test.

NOTE:

The PRESSURE bar graph and the PRESSURE display window
show the real-time expiratory pressure throughout SST.

7. When the last test in the sequence is complete, the EST completion status is
displayed (Table 4-9). Respond as indicated.

If certain tests do not pass, safe ventilation may be compromised, and the
ventilator is rendered inoperative until it is repaired. This is called a
ventilator failure. If certain other tests do not pass, but ventilation might not
be compromised (subject to a trained operator’s evaluation), this is called a
ventilator fault.

NOTE:

Faults detected during EST may not require the ventilator to be
serviced or removed from use immediately. A trained operator,
however, must evaluate the situation and determine whether the
ventilator can be used. Failures detected during EST require
immediate servicing and removal of the ventilator from clinical use.

5.1 Changing settings: a quick review

This section describes changing settings, switching between volume
control ventilation (VCV), pressure control ventilation (PCV, available on
the 760 Ventilator only) and pressure support ventilation (PSV), and
changing modes.

cannot change TIDAL VOLUME. You can change several settings at once,
or one at a time.

To change a setting: touch, turn, ACCEPT.

1. Touch the key: The key lights, the selected setting flashes, and the
message window shows the current setting, range, units, and name
of the setting. (If applicable, associated parameter information is also
displayed.)

2. Turn the knob to adjust the setting.

5.1.2 Switching between VCV, PCV, and PSV

To switch between breath types, you must first select a mode that allows it.
Follow the steps in Section 5.1.3 to change the mode.

If you try to select a breath type that is not allowed in the current mode, the
ventilator displays this message:

Choose mode before
choosing type

Table 5-1 summarizes which breath types are available on the 740 and
760 Ventilators, and when those breath types are selectable.

5.3 Adjusting apnea parameters

Warning

To ensure that the patient is ventilated appropriately in case of
apnea, you must review apnea parameters, and adjust them if
necessary.

NOTE:

During an APNEA alarm, you can change APNEA PARAMS but not
other settings.

You can view or change apnea parameters only when apnea ventilation is
possible (in SPONT mode, or in A/C or SIMV when RESPIRATORY RATE
is less than 6 /minute).

1. Press APNEA PARAMS to view apnea
parameter settings. When apnea
ventilation is possible, the ventilator
shows this message when you have
accepted settings and normal
ventilation has started:
