SAVE THESE INSTRUCTIONS.
This CPAP unit should be used only with masks recommended by the unit's
manufacturer, your physician, or respiratory therapist. To avoid rebreathing of
exhaled air 1) a mask should not be used unless the CPAP unit is turned on
and operating properly and 2) the vent hole(s) associated with the mask
should never be blocked. When the CPAP unit is turned on and functioning
properly, new air from the unit flushes the exhaled air out through the mask
vent hole(s). However, when the CPAP unit is not operating, exhaled air may
be rebreathed. Rebreathing of exhaled air for longer than several minutes
can, in some circumstances, lead to suffocation. This warning applies to most
CPAP units.

TRAVEL
This unit is equipped with a universal power supply capable of accepting line voltages
of 100-240V~, 50/60Hz. No adjustments are required to the AC power connector or
the line fuses to accept this entire range of voltages. If traveling to another country
where the line voltage is different than the domestic supply voltage, simply obtain a
line cord configured for that particular country with the appropriate international plug
and substitute it for the standard plug. Operate unit as normal.
INTRODUCTION
What is Obstructive Sleep Apnea (OSA)?
Obstructive Sleep Apnea (OSA) is a condition where the upper airway relaxes during
sleep causing the airway to obstruct. Apnea is the Latin word meaning "without
breath." People diagnosed with sleep apnea stop breathing repeatedly during sleep,
resulting in extreme exhaustion. High blood pressure, cardiac enlargement, and car-
diac arrhythmias are common, as are shortness of breath and loud snoring. In a 1993
report, the National Commission on Sleep Disorders Research stated that as many as 18
million Americans may have signs and symptoms of sleep apnea.
How does the DeVilbiss AutoAdjust LT nasal CPAP system work?
The DeVilbiss AutoAdjust LT nasal CPAP instrument provides non-invasive, continuous
air pressure to your upper airway, acting as an air "splint" to keep the airway passages
open during sleep. This reduces and eliminates the obstructive events, allowing unin-
terrupted sleep. The DeVilbiss AutoAdjust LT is designed to provide this therapy to you
quietly and comfortably so that your sleep is restorative and refreshing. The DeVilbiss
AutoAdjust LT nasal CPAP system offers automatic adjustment of air pressure by sens-
ing your air flow and compensating to meet your needs. AutoAdjust senses snoring and
changes in breathing flow and continually adjusts CPAP pressures in relation to these
changes. AutoAdjust increases CPAP pressures when snoring or specific breath flow
patterns are detected, and decreases the CPAP pressure during periods of sleep when
snoring or abnormal breath flows are not detected. The pressure profile changes are
gradual to prevent arousals of sleep architecture, but are timely to respond to respira-
tory events requiring pressure adjustments.
NOTE– This product has been designed for treatment of obstructive sleep apnea,
specifically for use in the adult patient population.
