1200, 1150,
NOTE
Pressure Support and Pressure Control breaths on the LTV® 1200 / 1150 are compensated for
PEEP. Delivered pressure is controlled by the Pressure Support or Pressure Control setting and is
affected by the PEEP setting. For example, a Pressure Support setting of 20cmH2O and a PEEP
setting of 10cmH2O results in a Peak Inspiratory Pressure (PIP) of 30cmH2O.
REMARQUE
La pression de support et le contrôle de la pression des respirations sur le LTV® 1200 / 1150 sont
compensés pour la pression expiratoire positive (PEP). La pression administrée est contrôlée par le
réglage de la pression de support ou par le réglage du contrôle de la pression et elle dépend du
réglage PEP. Par exemple, un réglage de la pression de support de 20 cmH2O et un réglage PEP de
10 cmH2O donnent une pression inspiratoire maximale (PImax) de 30 cmH2O.

Chapter 3 -
This chapter contains information regarding the breath types available on the LTV® 1200 / 1150
ventilator. It covers how breaths are initiated, limited and cycled, and when each type of breath is
given.
The following terms are used in discussing how breaths are given:
B
REATH TYPES
Initiate
Limit
Cycle
What causes a breath to be given. Breaths may be initiated by a patient trigger, a
push of the Manual Breath button, or by the ventilator based on the set breath rate
and ventilation mode.
How the breath is controlled. Breaths may be limited to a maximum circuit pressure
or flow.
What causes the breath to be cycled from the inspiratory phase to the exhalation
phase. Breaths may be cycled by the ventilator when a set time or delivered volume
has been reached, or when an alarm condition such as a high pressure limit has
been reached.
Breath Types
Breaths are defined by how they are initiated, limited and cycled. The breath types are Machine,
Assist, and Patient.
Machine Assist Patient
Initiated By - Ventilator Patient Patient
Limited By - Ventilator Ventilator Ventilator
Cycled By - Ventilator Ventilator Patient
Breaths may be given in any of the following forms: Volume Control, Pressure Control, Pressure
Support and Spontaneous.These breaths are given as described in the sections below.
In addition, the following parameters apply to all breaths:
The Minimum Inspiratory Time is 300 ms.
The Minimum Exhalation Time is 346 ms.
When patient triggers are enabled, triggers are detected during exhalation after the Minimum
Exhalation Time has expired.

Volume Control Breaths
For Volume Control breaths, the set Tidal Volume is delivered over the set Inspiratory Time and flow
is delivered in a decelerating taper flow waveform. Peak flow is calculated based on the Tidal Volume
and Inspiratory Time and the final flow is 50% of the peak flow. Volume breaths may be machine or
assist type breaths.
When the combination of inspiratory time and tidal volume result in an initial flow of <20 Lpm, the final
flow remains at 10 lpm and the waveform is flattened.

P/N 19802-001 Rev. F
Page 34
Pressure Control Breaths
For Pressure Control breaths9, flow is delivered to elevate the circuit pressure to the Pressure Control
setting and maintain it at that pressure for the set Inspiratory Time. Pressure Control breaths may be
machine or assist type breaths.
Adjusting the Rise Time Profile changes the flow and pressure waveforms for Pressure Control
breaths.

Pressure Control and Pressure Support breaths do compensate for PEEP. For example, a Pressure Control
setting of 20cmH
(20 cmH
0 over the set PEEP).

Page 35
Pressure Control Breaths (cont)
Pressure Control breaths have an optional flow termination criteria. If PC Flow Termination is ON
Pressure Control breaths may be time or flow terminated. If the flow drops to the set FLOW TERM
level before the inspiratory time is completed, the inspiration is cycled.

P/N 19802-001 Rev. F
Page 36
Pressure Support Breaths
For Pressure Support breaths10, flow is delivered to elevate the circuit pressure to the Pressure
Support setting and maintain it at that pressure until the flow drops below a variable percentage of the
peak flow. Pressure Support breaths may also be cycled by a variable time limit, or by exceeding 2
breath periods. Pressure support breaths are patient type breaths.
For some patients, it may be useful to adjust the variable flow termination percentage. Adjusting the
FLOW TERM setting between 10% and 40% will change the length, volume and comfort of the
inspiration.

Pressure Control and Pressure Support breaths do compensate for PEEP. For example, a Pressure Control
setting of 20cmH
(20 cmH
0 over the set PEEP).

Spontaneous Breaths
For Spontaneous breaths, flow is delivered to meet patient demand and maintain the circuit pressure
at the measured PEEP from the previous breath. The breath is cycled when the flow drops below the
Pressure Support Flow Termination setting, or below 3 lpm. Spontaneous breaths may also be
terminated by exceeding 2 breath periods. Spontaneous breaths are patient type breaths.

Page 39
SIMV Mode
SIMV mode is selected when SIMV/CPAP is selected and the Breath Rate is set between 1 and 80.
In SIMV mode, machine, assist and patient breaths may be given.
For the first patient trigger detected within a breath period, an assist breath is given. For all
subsequent patient triggers within the same breath period, spontaneous patient breaths or pressure
support if set, are given.
At the beginning of a breath period, if no triggered breaths were given in the previous breath period, a
machine breath is given. If there was a patient trigger in the previous breath cycle, the ventilator will
not give a machine breath in the current breath period unless the set Apnea Interval is exceeded.
NOTE
LTV® ventilators provide an Apnea Backup mode of ventilation. When the set Apnea Interval
(maximum time allowed between the beginning of one breath and the beginning of the next breath) is
exceeded, the APNEA alarm is generated and the ventilator will enter Apnea Backup ventilation
mode.

NPPV Mode
Non-invasive Positive Pressure Ventilation, (NPPV) can be selected as the primary mode of
ventilation. In the NPPV mode, the ventilator cycles between IPAP (Pressure Support) and EPAP
(PEEP). When a patient trigger is detected, a Pressure Support patient breath is given.
WARNING
Masks used with the LTV® 1200 / 1150 must be non-vented (no holes or leak vents). With a vented
mask, the patient's exhaled air escapes through holes or vents in the mask, elbow or swivel
connector. With a non-vented mask, the patient's exhaled air escapes through the ventilator
exhalation valve. Using a vented mask will deplete the oxygen supply faster, and also may lead to
patient-ventilator dysynchrony.
Excessive leakage can also occur if the mask is not properly sealed to the patients face.
REMARQUE
Les masques utilisés avec le LTV® 1200 / 1150 ne doivent pas être ventilés (ni trous ni
épanchements d’air). Avec un masque de ventilation, l’air que le patient expire s’échappe par les
trous ou la ventilation du masque, le coude ou le connecteur pivotant. Avec un masque qui n’a pas de
ventilation, l’air que le patient expire s’échappe à travers la valve d’expiration du ventilateur. Utiliser
un masque de ventilation va épuiser la réserve d’oxygène plus rapidement et peut aussi causer une
dysynchronie entre le patient et le ventilateur.
Des fuites excessives peuvent aussi se produire si le masque n’est pas proprement étanche sur le
visage des patients.

Apnea Backup
®
The LTV
1200 / 1150 ventilator provides an Apnea Backup mode of ventilation. Apnea Backup
ventilation begins when the time since the last breath start is greater than the set Apnea Interval.
When an apnea alarm occurs:
If an inspiration is in progress, the ventilator cycles to exhalation.
The ventilator begins Apnea Backup ventilation in the Assist/Control mode according to the
current control settings. The active controls are displayed at full intensity, and all other controls
are dimmed.
The breath rate for Apnea Backup mode is determined as follows:
If the set Breath Rate is = 12 bpm, the Apnea breath rate is the set Breath Rate.
If the set Breath Rate is < 12 bpm and the set Breath Rate is not limited by other control settings,
the Apnea breath rate is 12 bpm.
If the set Breath Rate is limited to <12 bpm, the Apnea breath rate is the highest allowed rate.
The ventilator exits the Apnea Backup mode and returns to the previous mode of ventilation when the
operator resets the Apnea alarm or when two consecutive patient-initiated breaths occur.
The Apnea Interval may be changed using the Extended Features menu.

Volume Pressure Ventilation
The LTV® 1200 / 1150 ventilator offers both Volume and Pressure ventilation.
When Volume is selected, all machine and assist breaths are Volume Control breaths. Breaths are
given according to the Tidal Volume and Insp. Time controls. For more information on Volume
Control breaths, see Chapter 6 - Controls, Tidal Volume.
When Pressure is selected, all machine and assist breaths are Pressure Control breaths. Breaths
are given according to the Pres. Control and Insp. Time controls. For more information on Pressure
Control breaths, see Chapter 6 - Controls, Pressure Control.
Bias Flow
The LTV® 1200 / 1150 ventilator provides a constant bias flow of 10 Lpm during exhalation to assist
with patient triggering. When the O2 Conserve option is ON, the bias flow is 0 lpm and assistance
with patient triggering is reduced. For more information on bias flow using the O2 Conserve option,
see Chapter 10 - Extended Features, O2 Conserve.
WARNING

Setting a Control
®
There are 5 kinds of controls on the LTV
1200 / 1150 ventilator. They are:
Variable Controls
Buttons
Set Value Knob
Controls and alarms that have front panel displays.
Push buttons that select an option or perform a function.
Used to set control values and navigate extended features
menus.
Extended Features
Ventilation options that do not have front panel controls but are
available through a special menu.
Mechanical Controls
Controls, such as Over Pressure Relief, that are hardware
regulated and not operator adjustable.
The following sections describe how to set each kind of control.
Variable Controls
To set a variable control:
1) Select the control by pushing the associated button. The display for the selected control will be
displayed at normal brightness, but the remaining control displays will dim.
2) Change the control value by rotating the Set Value knob. Rotate clockwise to increase and
counter-clockwise to decrease the value. Turning the control knob slowly will change the setting
by a small increment. Turning the control knob more quickly will change the setting by a larger
increment.
3) Deselect the control by:
Waiting 5 seconds, or
Pushing the selected button again, or
Selecting another control, or
Pushing the Control Lock button
When the control is deselected, all displays will return to their normal brightness. The new control
value goes into effect as soon as the control is deselected.

Buttons
Button controls do one of three things:
Turn a feature on or off, such as Control Lock.
Toggle between two features, such as Volume or Pressure ventilation.
Perform a function, such as Manual Breath.
Push the button to activate the feature or change the feature state. A green LED next to the button
indicates when a feature is on.
For Mode buttons, there is a second confirmation push required. To toggle between modes:
1) Push the mode button. The associated LED will flash for 5 seconds.
2) To confirm the mode change, push the mode button again while the LED is flashing. The
ventilator will begin operating in the new mode.
To prevent an accidental shutdown, the ventilator requires a longer push of the On/Standby button to
put the ventilator in the Standby state. To put the ventilator in Standby, push and hold the
On/Standby button for 3 seconds.
Set Value Knob
Use the Set Value knob to set control values and navigate extended features menus.
To change the setting for a variable control, select the control then turn the knob clockwise or
counter-clockwise until the desired setting is reached.
For information on how to use the Set Value knob to navigate the extended features menus, see

Bright, Dim and Blank Control Displays
Variable controls will be displayed at normal or dimmed intensity, or may be blanked. A display will be
displayed at normal intensity:
When it is selected for change. All other displays will be dimmed.
When it is active in the current ventilation mode. Dimmed displays are not active in the current
mode.
NOTE
Be sure to set any controls that may be used in Apnea Backup ventilation to appropriate values. Even
though these controls are dimmed, they will be used if apnea should occur.
REMARQUE
Assurez-vous de régler aux valeurs appropriées, tous les contrôles susceptibles d'être utilisés en
mode ventilation de secours pour l'apnée. Même si ces contrôles sont en veilleuse, ils seront utilisés
en cas d'apnée.
A display will be displayed at dimmed intensity:
When another control is selected for change.
When it is not active in the current ventilation mode.
A display will be blank:
To conserve battery power while operating from battery power:
If no button pushes or control knob activity occurs for 60 seconds, the displays are turned off.

Flashing Controls
Variable controls and alarms will be displayed solid or flashing. A flashing control means one of the
following things:
If you are changing a control setting, and the display flashes, you have reached a limited value for
the control. Control Limiting is covered later in this section.
If an alarm display flashes, it indicates that an alarm has occurred or is occurring. See Chapter 9 -
Ventilator Alarms for more information on this.
If a control display flashes, it indicates a special condition such as time termination of a pressure
support breath. For more information, see Chapter 6 - Controls.
If the Control Lock LED flashes, it indicates you have tried to change the control settings while
the front panel controls are locked. For more information, see Chapter 6 - Controls, Control Lock.
Dashes
If a control display is set to dashes “ - - ”, it indicates that control is turned off, or is not available in
the current ventilation mode.
Control Limiting
Variable control settings may be limited to less than their specified range for any of the following
reasons:
To prevent inverse I:E ratios of greater than 4:1
To ensure a minimum inspiration time of 300 ms
To ensure a minimum exhalation time of 346 ms
To ensure a minimum initial flow of 10 lpm for Volume Controlled breaths
To ensure a maximum initial flow of 100 lpm for Volume Controlled breaths
When you are updating a control and have reached a limited condition, the following things happen:
The control stops updating and will remain displayed at the highest (or lowest) allowed value.
The control display will flash.
The displays for other controls involved in the limited condition will flash.
To set the control to a value outside the limited range, you will need to change the settings for other
controls involved in the limit condition. For instance, if the Breath Rate is set to 12, the maximum
allowed Inspiratory Time is 4.0 seconds. To set the Inspiratory Time to more than 4.0 seconds, you
must first decrease the Breath Rate.

Tidal Volume
Use the Tidal Volume control to establish the volume of gas which the ventilator will produce and
deliver during Volume Controlled breaths. Flow is delivered in a taper waveform over the set
Inspiratory Time. The peak flow is calculated based on the Tidal Volume and Inspiratory Time with a
maximum flow of 100 lpm and a minimum flow of 10 lpm. Flow is decelerated from the calculated
peak flow to 50% of the calculated peak flow.
While the Tidal Volume is being updated, the Calculated Peak Flow is displayed in the display
window.
The Effect of Altitude or Barometric Pressure on Delivered Tidal Volume
Altitude / barometric pressure have an affect on the actual tidal volume delivered to the patient by the
®
ventilator.
LTV
To prevent potential over delivery of tidal volume when Volume ventilation is required, use the
following instructions to calculate a Tidal Volume control setting necessary to compensate for the
effect of altitudes above 6,500 feet sea level or barometric pressures less than 605 mmHg.
1) Ascertain the pertinent environmental condition (altitude or barometric pressure) in which the
ventilator is to be operated.

Altitude
6,500 feet sea level and is NOT contained within a pressurized compartment (e.g. a
pressurized aircraft cabin)

compartment that the ventilator is to be operated within
2) Refer to the table on the next page, select the row in which the listed altitude or barometric
pressure is closest to the pertinent environmental condition and scroll across to the “Volume
Compensation Factor” column to determine the associated compensation factor.
3) Per the equation shown below, the “Tidal Volume (ml) control setting” to be used/set is equal
to the “Intended Tidal Volume (ml)” to be delivered, divided by the “Compensation Factor”.

WARNING
Battery run time - When the battery reaches the BAT LOW level, the ventilator will only run for
approximately 10 minutes before generating a battery empty alarm (BAT EMPTY). The approximate
times shown here are based on tests using the nominal settings, a new battery and a full 8- hour
charge cycle as specified in Appendix A - Ventilator Specifications. Actual run time may be more or
less depending on ventilator settings, patient demand, and battery age or condition. It is highly
recommended that an alternate power source is secured PRIOR to the ventilator reaching the BAT
EMPTY alarm condition to ensure continuous, uninterrupted patient ventilation.
AVERTISSEMENT
Durée d’utilisation de la batterie – Lorsque la batterie atteint le niveau BAT INT BASS, le
ventilateur fonctionne pendant environ 10 minutes avant d’émettre une alarme de batterie faible (BAT
INT VIDE). Cette durée approximative est basée sur des tests avec des paramètres nominaux, une
nouvelle batterie et un cycle de chargement complet de 8 heures, tel que spécifié dans l’Annexe A –
Spécifications du ventilateur. La durée d’utilisation réelle pourrait être supérieure ou inférieure, selon
les paramètres du ventilateur, la demande du patient et l’âge ou l’état de la batterie. Il est fortement
recommandé qu’une source d’alimentation alternative soit connectée AVANT que le ventilateur
n’atteigne l’état d’alarme BAT INT VIDE afin d’assurer une ventilation continue et ininterrompue au

Charge Status
The Charge Status indicator shows the charge state of the internal battery. This LED is on when the
ventilator is supplied with external power and the internal battery is being charged. The charge status
is indicated as follows:
LED Color Charge Status
Flashing Amber The ventilator is performing pre-charge testing of the battery before
starting the charge process. This occurs when external power is first
connected. The process normally takes a few seconds but may take up to
an hour on a deeply discharged battery.
Green The internal battery is charged to full level. While in this state, the charger
will continue to trickle charge the battery.
Amber The internal battery is being bulk charged. The battery has not reached a
full charge level yet.
Red The ventilator has detected a charge internal battery fault. The internal
battery cannot be charged.
CAUTION
Charge Fault - If the Charge Status LED indicates a charge fault, contact a certified CareFusion
service technician immediately.
Internal Battery Use: The internal battery is intended for use during short periods while switching
between external power supplies, in emergencies or for short duration transports. The length of time
the ventilator will operate on internal power is a function of factors such as settings, charge level and
condition of the battery; therefore, the use of the internal battery as a standard operating practice is
not recommended.
ATTENTION
Erreur de charge - Si le DEL de l'état de charge indique une erreur de charge, veuillez contacter
immédiatement un technicien de service certifié CareFusion.
Utilisation de la batterie interne: La batterie interne est conçue pour être utilisée sur de courtes
périodes pendant la commutation entre des connexions d’alimentation externe, les situations
d’urgence ou les transports de courte durée. La durée pendant laquelle le ventilateur fonctionnera sur
l’alimentation interne dépend de facteurs tels, la configuration, le niveau de la charge et la condition
de la batterie; l’utilisation de la batterie interne pour l'opération normale n’est donc pas
