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.
