ROUBLESHOOTING
This chapter describes troubleshooting for the LTV
®
Series ventilator. Some problems can result from
improper operation and can easily be corrected without any modification to the ventilator. Other
problems may require that the ventilator be recalibrated or have parts replaced.
Do not attempt to repair or replace any part of the ventilator unless you are trained and
authorized for service on the LTV
®
Series ventilator.
This chapter is organized into five sections:
Displays and Buttons (See page 15-2) Includes problems with control and window displays
and with setting controls.
Ventilator Performance (See page 15-5) Includes problems with delivered or monitored
pressure, volume or PEEP, accuracy, sensitivity and
triggering.
Power and Battery Operation
(See page 15-14)
Includes problems with turning the ventilator on,
operating from external power sources, battery
operation or duration, and vent inops.
Alarms (See page 15-16) Includes problems with recurring alarms.
Checkout Test Failures (See page 15-23) Includes problems detected while performing the
VENT CHECK tests.
Test Lung Operation (See page 15-25) Includes problems encountered when operating the
ventilator with a test lung.
The troubleshooting tables are organized by symptom, then by possible causes and methods of
diagnosing and resolving the problem. If you do not find the symptom you are looking for under one
section, you may find it listed under another section, or you may be able to diagnose the problem by
reading sections with related symptoms. For information on resolving problems that are not listed
here, contact Pulmonetic Systems.
