Warnings
WARNING
Untrained Personnel – Only properly trained personnel should operate the ventilator. The LTV®
Series ventilator is a restricted medical device designed for use by Respiratory Therapists or other
properly trained and qualified personnel under the direction of a physician and in accordance with
applicable state laws and regulations.
Leak Testing the Patient Breathing Circuit – The patient circuit must be leak tested in the VENT
CHECK mode before connection to the patient. In addition, the Ventilator Checkout mode should be
used to check for correct operation of the ventilator alarm, displays and controls. Harm to the patient
or ineffective ventilation may result from failure to leak test the patient breathing circuit before
connection to a patient. When using a heated humidifier, include it in the circuit when performing leak
testing.
Adjustable and Critical Alarms – For safety purposes, all adjustable alarms and all critical alarms
must be checked to insure proper operation.
Alarms Function Verification - All alarms must be verified as functioning properly on a daily basis. If
any alarm malfunctions, immediately contact a certified Pulmonetic Systems’ service technician or
Pulmonetic Systems.
Patient Monitoring - Patients who are dependent on a ventilator should be constantly monitored by
qualified personnel. Such personnel should be prepared to address equipment malfunctions and
circumstances where equipment becomes inoperative. An alternative method of ventilation should be
available for all patients dependent on the ventilator, and qualified personnel should be fully familiar
with emergency ventilation procedures.
Alternative Ventilation - It is recommended that an alternative means of ventilating the patient be
available at all times and that all ventilator operators be fully familiar with emergency ventilation
procedures.
Fire or Explosion - Operation of the LTV®Series ventilator in the presence of flammable gases could
cause a fire or explosion. Under no circumstances is the ventilator to be operated when explosive
gases are present. The presence of nitrous oxide or flammable anesthetics presents a danger to the
patient and operator.
Patient Breathing Circuit Disconnection - Inadvertent disconnection of the patient from the patient
breathing circuit can be dangerous.
Critical Alarms - Failure to set the critical alarms such as the Low Minute Volume alarm and the Low
Pressure alarm may cause non-detection (no alarm) for a disconnection of the lower sense line or the
exhalation valve drive line.
Exhalation Valve Diaphragm – Patient ventilation may be ineffective or dangerous if the exhalation
valve diaphragm is damaged or worn out. The exhalation valve diaphragm must be inspected on a
daily basis and replaced whenever necessary.
Sustained HIGH PRES Alarm - During a sustained High Pressure alarm condition (HIGH PRES), the
ventilator’s turbine is stopped and gas is not delivered to the patient. Disconnect the patient from the
ventilator and ventilate the patient using an alternative method. See Chapter 15 - Troubleshooting,
Alarms for additional information concerning the HIGH PRES alarm.

Page 1-4 LTV®Series ventilator Operator’s Manual
p/n 10664, Rev. Y
WARNING
BAT EMPTY Alarm - A BAT EMPTY alarm indicates the internal battery is almost depleted. Connect
the ventilator to an external power source immediately.
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
time shown is 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 connected PRIOR to the ventilator reaching the BAT EMPTY alarm
condition to ensure continuous, uninterrupted patient ventilation
INOP Alarm - If an INOP alarm occurs during operation, ventilate the patient using an alternative
method, disconnect the ventilator, and immediately contact a certified Pulmonetic Systems’ service
technician or Pulmonetic Systems.
NO CAL Condition - Operation of the LTV®Series ventilator under a NO CAL condition may result in
inaccurate pressure and volume measurements. Should this condition occur, disconnect the patient
from the ventilator, provide an alternative method of ventilation and immediately contact a certified
Pulmonetic Systems’ service technician or Pulmonetic Systems.
XDCR FAULT Alarm - Continued operation of the LTV®Series ventilator with an activated XDCR
FAULT alarm may result in inaccurate flow and volume measurements. Should this condition occur,
disconnect the patient from the ventilator, provide an alternative method of ventilation and
immediately contact a certified Pulmonetic Systems’ service technician or Pulmonetic Systems.
Personal Injury and Electric Shock - Operation of the LTV®Series ventilator if any of its panels
have been removed may result in electrical shock to the patient or operator. All servicing must be
performed by a certified Pulmonetic Systems’ service technician.
NPPV Mode – NPPV1is not a life support mode and is not suitable for patients that require life
support ventilation. NPPV Mode should only be used for supplemental ventilation of non-life support
patients.
NPPV Mode - When operating in NPPV1mode, many of the standard alarms are disabled. This may
result in reduced ventilation accuracy should a problem occur. Carefully read Chapter 4 - Ventilation
Modes, NPPV, before selecting this mode of operation.
Accuracy of PEEP setting - Variations in the patient’s breathing pattern and/or leaks in the patient
circuit (including leaks around the tracheostomy tube cuff) can affect PEEP. PSI recommends that the
clinician set the PEEP to the prescribed level on a test lung while observing the PEEP value in the
LTV display window. The clinician should also periodically monitor the PEEP value in the LTV display
window. Using an inaccurate PEEP setting due to a patient leak can result in less than prescribed
PEEP or undesirable increases in patient circuit pressure when the patient circuit leak changes.
Audible Alarms - Failure to immediately identify and correct audible alarm situations may result in
serious patient injury.

Operator’s Manual LTV®Series ventilator Page 1-5
p/n 10664, Rev. Y
WARNING
Equipment Malfunction or Failure - The LTV®Series ventilator has alarms to notify operators of
certain conditions and to cease operating upon detecting possible danger. In the event of equipment
failure, all ventilator operators should have an alternative method of ventilation available and be fully
familiar with emergency ventilation procedures.
Improperly Functioning Ventilator - Operation of a ventilator that does not appear to be working
properly may be hazardous. If the ventilator is damaged, fails Ventilator Checkout tests or
malfunctions in any way, discontinue its use and immediately contact a certified Pulmonetic Systems’
service technician or Pulmonetic Systems.
Ventilator Checkout Tests – Be aware that gas is not delivered to the patient during these tests.
Disconnect the patient from the ventilator and ventilate the patient using an alternative method before
running the Ventilator Checkout tests.
Ventilator Checkout and Maintenance Modes - The LTV®Series ventilator does not deliver gas
during the Ventilator Checkout mode (VENT CHECK) or Ventilator Maintenance mode (VENT
MTNCE) and should not be used to ventilate a patient during these tests.
Inspired Oxygen (FIO2) Concentration – If the patient has a variable respiratory rate, his/her
minute ventilation will fluctuate. If exact concentrations of inspired oxygen (FIO2) are required to be
delivered to the patient, it is recommended that an accurate oxygen analyzer with alarms be used.
O2 Cylinder Duration Information - The accuracy of the displayed useable amount of oxygen
remaining in an external O2 cylinder (O2 DUR hh:mm) is dependant on the precision of the pressure
gauge used on the O2 cylinder and the accuracy of the information provided by the operator in the O2
CYL DUR menu settings. The calculated/displayed useable amount of oxygen information is to be
used for reference purposes only.
Ventilation Variables and O2 Consumption - Variations in the patient’s minute ventilation, I:E ratio
and/or ventilator setting changes or equipment status (i.e. circuit leaks) affect the consumption rate of
oxygen. When warranted by a patients condition, it is recommended that a back-up cylinder or
alternative source of oxygen be available at all times.
Before Using Automobile Cigarette Lighter or Power Outlets - Before using Automobile Cigarette
Lighter or Power Outlets as a power source for the LTV®ventilator, assure that the ventilator’s
internal battery is in good condition and fully charged. Poor cigarette lighter or power outlet
connections, electrical system defects (battery, charging system, etc.), or use of vehicle accessories
(air conditioner, high current lights, high power audio equipment, etc.) could result in less than the
required voltage being delivered to the ventilator, generate a Power Lost alarm and switch the
ventilator’s power source to the internal battery.
Unauthorized Parts or Accessories – Serious harm to the patient may result from the use of
unauthorized parts or accessories. Only items expressly approved by Pulmonetic Systems may be
used in conjunction with the LTV®Series ventilators.
Unapproved Adapters – Only Pulmonetic Systems Accessories should be used to connect the
ventilator to Patient Assist Call Systems. These accessories incorporate safety features to reduce the
risk of shock. Do not attempt to modify these accessories in any way.
Patient Assist Call Connector – Do not apply more than 25V rms or 32VDC to the Patient Assist
Call connector.

WARNING
Ventilator Service and Repair - All servicing or repair of the LTV®Series ventilator must be
performed only by a service technician certified by Pulmonetic Systems
Disabled Oxygen Inlet Pressure Alarms - When the oxygen blending option is not installed, the
Oxygen Inlet Pressure Alarms are disabled.
Patient Circuits – Pulmonetic Systems Patient Circuits, Exhalation Valve Assemblies and Water
Traps are shipped clean, not sterile.
Ultra Violet Light Sensitivity – The material used in the tubing of the “Re-usable” Patient Circuits is
not UV stable. Avoid exposure of the tubing to UV light.
PEEP Valve Rotation – Attempting to adjust the PEEP valve counterclockwise past zero (0) may
damage the PEEP valve assembly or cause circuit leaks.Accessories
Mounting Screws - Refer to the information contained in Pulmonetic Systems Replacement Screws
Kit, P/N 11149, to determine the appropriate accessories mounting screws or accessories
replacement screws location, type and length to use when removing or exchanging external
accessories on an LTV® Series ventilator.
Mounting Screw Use – Internal damage to the ventilator may result if the wrong length mounting
screws are used when installing or removing external accessories.
Specific Boot Replacement Screw Location - One leg of the upper protective boot has an
additional screw hole (furthest from the end of the leg); On earlier version ventilators (screw was
located in the upper hole in the leg of the boot) the use of a 3/16” mounting screw is required. On
current version ventilators (screw was located in the lower hole in the leg of the boot) the use of a 1/4”
mounting screw is required.
Specific Boot Installation Screw Location - One leg of the upper protective boot has an additional
screw hole (furthest from the end of the leg); On earlier version ventilators, the screw hole will align
with the upper hole in the boot and requires the use of the 1/4” mounting screw. On current version
ventilators, the screw hole will align with the lower hole in the boot and requires the use of the 3/8”
mounting screw.
Patient Circuit Accessories - The use of accessories such as Speaking Valves, Heat-Moisture
Exchangers and Filters create additional patient circuit resistance and in the event of a disconnection,
may impede the generation of a Low Pressure Alarm. Ensure that the Low Pressure Alarm settings
accommodate these types of accessories when used in combination with patient circuits.
Low Minute Volume Control Settings - The Low Minute Volume control should be set to its highest
clinically appropriate value. If there is a clinical need to set the Low Minute Volume alarm to lower
values or off (“- - -“), perform a clinical assessment to determine if an alternative monitor (i.e. a Pulse
Oxymeter with an audible alarm, or a Cardio Respiratory Monitor) should be used.

AVERTISSEMENT
Personnel non qualifié - Seul le personnel qualifié doit opérer le ventilateur. Le ventilateur de la
série LTV®est un dispositif médical restreint conçu pour être utilisé par les inhalothérapeutes ou
autres personnes qualifiées, et par le personnel qualifié sous la supervision d'un médecin et en
conformité avec les lois et règlements applicables.
Contrôle de l’étanchéité du circuit respiratoire du patient – L'étanchéité du circuit respiratoire du
patient (vérification de ventilation) doit être vérifiée en mode VENT CHECK avant le raccordement au
patient. En outre, on doit utiliser le mode Ventilator Checkout (vérification du ventilateur) afin de
s’assurer du fonctionnement adéquat de l’alarme, des affichages et des commandes du ventilateur.
Le défaut de vérifier l’étanchéité du circuit respiratoire du patient avant le raccordement à un patient
peut être nocif pour le patient ou provoquer une ventilation inefficace. Lorsqu’un humidificateur
chauffant est employé, il convient de l’inclure dans le circuit en procédant à la vérification de
l’étanchéité.
Alarmes ajustables et critiques - Afin d'assurer l'opération sécuritaire des ventilateurs de la série
LTV®, toutes les alarmes ajustables doivent être réglées avant l'opération. De plus, toutes les
alarmes critiques (par exemple, alarme de basse pression), doivent être inspectées avant de laisser
le patient seul.
Vérification du fonctionnement des alarmes - Toutes les alarmes sonores et visuelles doivent être
vérifiées quotidiennement. Si une des alarmes fonctionne de façon inadéquate, contactez votre
technicien de service certifié de Pulmonetic Systems ou Pulmonetic Systems.
Surveillance du patient – Un personnel qualifié doit constamment surveiller les patients qui sont
reliés à un ventilateur. Le personnel doit être en mesure de s’occuper des défectuosités de
fonctionnement de l’équipement ainsi que des circonstances où ce dernier devient inopérant. Une
forme de ventilation alternative doit être disponible à tous les patients reliés au ventilateur et le
personnel qualifié devrait être pleinement familier avec les procédures de ventilation d’urgence.
Ventilation alternative - Il est recommandé qu'un moyen alternatif de ventilation soit disponible en
tout temps, et que tous les opérateurs de ventilateur soient pleinement familiers avec les procédures
de ventilation d'urgence.
Feu ou explosion - L'opération des ventilateurs de la série LTV®en présence de gaz inflammables
peut causer un feu ou une explosion. Le ventilateur ne doit être opéré sous aucune circonstance en
présence de gaz. La présence d'oxyde nitreux ou d'anesthésiques inflammables représente un
danger pour le patient et l'opérateur.
Débranchement du circuit respiratoire du patient - Le débranchement accidentel du circuit
respiratoire du patient peut s'avérer dangereux.
Alarmes critiques – Le défaut de définir les alarmes critiques telles que l’alarme basse ventilation-
minute et l’alarme basse pression peut causer une non-détection (absence d’alarme) pour un
débranchement du tube de détection inférieur ou du tube d’entraînement de la soupape d’expiration.
Diaphragme de la soupape d'expiration - Une ventilation inefficace ou dangereuse pour le patient
peut résulter si le diaphragme de la soupape est endommagé ou usé. Le diaphragme de la soupape
d'expiration doit être vérifié quotidiennement, et remplacé au besoin.
Alarme ALARME PMAX continue — Dans des conditions d’alarme de haute pression prolongées
(ALARME PMAX), la turbine du ventilateur s'arrête et le gaz n’est plus transmis au patient.
Débranchez le patient du ventilateur et utilisez une autre méthode de ventilation. Pour plus de détails
sur l’état ALARME PMAX, reportez-vous au chapitre 15, Troubleshooting, Alarms.

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
patient.
Alarme BAT EMPTY - Une alarme BAT EMPTY indique que la pile interne est pratiquement à plat.
Branchez immédiatement le ventilateur à une source d'alimentation externe.
Alarme INOP - Si une alarme INOP survient au cours de l'opération, ventilez le patient à l'aide de la
méthode alternative, retirez immédiatement le ventilateur du service, et contactez immédiatement
votre technicien de service certifié de Pulmonetic Systems ou Pulmonetic Systems.
Condition NO CAL - L'opération continue du ventilateur de la série LTV®sous condition NO CAL
peut résulter en mesures de pression et de volume erronées. Si cette condition se présente, le
ventilateur doit être retiré du service, et vous devez immédiatement contacter votre technicien de
service certifié de Pulmonetic Systems ou Pulmonetic Systems.
Alarme XDCR FAULT - L'opération continue du ventilateur de la série LTV®avec une alarme XDCR
FAULT activée peut résulter en mesures de débit et de volume erronées. Si cette condition se
présente, le ventilateur doit être retiré du service, et vous devez immédiatement contacter votre
technicien de service certifié de Pulmonetic Systems ou Pulmonetic Systems.
Blessures personnelles et chocs électriques - L'opération d’un ventilateur de la série LTV®alors
que ses panneaux sont enlevés, peut causer un choc électrique au patient ou à l'opérateur. Tout
entretien doit être effectué par un technicien de service certifié de Pulmonetic Systems.
Mode NPPV – Le mode NPPV n’est pas un mode de maintien des fonctions vitales continu et il n’est
pas approprié pour les patients qui ont besoin d’une ventilation continue pour le maintien des
fonctions vitales. Le mode NPPV ne doit être utilisé que comme ventilation supplémentaire pour les
patients qui ne nécessitent pas de maintien des fonctions vitales.
Mode NPPV – Lorsque l’appareil fonctionne en mode NPPV, bon nombre des alarmes standards
sont désactivées. Par conséquent, si un problème survient, la précision de la ventilation pourrait
diminuer. Assurez-vous de lire attentivement le chapitre 4 – Types de respiration et modes de
ventilation, mode NPPV avant de choisir ce mode de fonctionnement.
Exactitude du paramètre PEP – Les écarts dans le mode de respiration du patient et/ou les fuites
du circuit du patient (y compris les fuites autour du ballonnet pour canule de trachéostomie) peuvent
affecter le PEP. Des études et investigations préliminaires recommandent que le clinicien définisse le
PEP au niveau prescrit sur un poumon d’essai tout en observant la valeur PEP de l’écran graphique
LTV. Le clinicien doit par ailleurs surveiller de façon périodique la valeur PEP de l’écran graphique
LTV. L’utilisation d’un paramètre PEP inapproprié en raison d’une fuite de patient peut
potentiellement résulter en un paramètre inférieur au paramètre PEP prescrit ou en une
augmentation indésirable de la pression du circuit du patient lorsque la fuite du circuit du patient
change.
Alarmes sonores - L'échec à identifier et à corriger dans l'immédiat les situations d'alarmes sonores
peut causer des blessures au patient.
