Introduction

In 1993, the National Commission on SleepDisorders Research stated that as many as18 million Americans may have signs andsymptoms of Obstructive Sleep Apnea(OSA). OSA is a condition where the upperairway relaxes during sleep causing the airway to obstruct. Apnea is a word meaning “without breath.” People diagnosedwith OSA stop breathing repeatedly duringsleep which can result in extreme exhaustion and damage to vital organs.

HOW DOES THE REMREST HELP?The RemRest is a CPAP (Continuous PositiveAirway Pressure) device which providesconstant non-invasive air pressure to yourupper airway causing the airway to stayopen. In doing so, you are able to sleepwith no interruption allowing your body torest and regenerate. Small, adjustable,lightweight and quiet, the RemRest is ourcontribution to reaching your dreams.

RemRest 7

The RemRest system consists of a CPAP flowgenerator, tubing and a nasal interface.Other accessories may be used and areavailable as needed from your care provider.Comfortable fit is very important. Please discuss with your care provider to determinethe best nasal interface that will meet your needs.

WARNINGDo not under any circumstances plug anyvent holes on your mask. These are forproper exhaling and plugging them mightcause carbon dioxide buildup. This warningdoes not pertain to any capped holes on yourmask. These are for diagnostic purposes andmay remain plugged.

WARNINGThis CPAP unit should be used only withmasks (and connectors) recommended bythe manufacturer of the CPAP machine, your physician, or respiratory therapist. A maskshould not be used unless the CPAP is turnedon and operating properly.

Explanation of the Warning: This CPAP unit isintended to be used with special masks (or connectors) which have vent holes to allow continuous flow of air out of the mask. Whenthe CPAP unit is turned on and functioningproperly, new air from the CPAP machineflushes the exhaled air out through the maskvent hole. However, when the CPAP machineis not operating, enough fresh air will not beprovided through the mask, and exhaled airmay be rebreathed. Rebreathing of exhaled

air for longer than several minutes can insome circumstances lead to suffocation.This warning applies to most models ofCPAP units.

CAUTIONAt low CPAP pressures, the flow through theexhalation port may be inadequate to clearall exhaled gas from the tubing. Somerebreathing may occur. This warning appliesto devices with rebreathing testing whichdemonstrates that rebreathing may occur atlow pressures within the operating pressure range of the device.

CAUTIONThe air flow for breathing produced by thisdevice can be as much as 4°F higher thanthe temperature of the room. Cautionshould be exercised if the room temperatureis warmer than 90°F. (This caution appliesto devices in which the temperature of theoutput of the device is more than 3°F aboveambient under typical test conditions.)

REMREST TUBING SET-UPSmooth-bore tubing is designed to deliverair pressure to your nasal interface. Attachone end of your tubing to the RemRest air outlet. The other end of the tubing is usedfor the nasal interface. See diagram onpage 5. When humidifier or oxygen equipment is used with the RemRest system, please follow the user instructionsprovided with the humidifier or oxygenequipment to set up the system. For bestresults, it is recommended you use theRemRest Heated Humidifier with this device.

WARNINGThis device is not suitablefor use in the presence ofa flammable anaesthetic mixture with air or withnitrous oxide.

WARNINGThis is not intended for use as a life supporting or life sustaining device.It is intended for use on spontaneously breathing adults.

WARNINGAll settings of yourRemRest are to be adjusted by authorizedpersonnel. Settings are theresult of physician supervised diagnosis andmust not be changedwithout physician authorization.

RemRest Flow Generator Operation• Place the RemRest device on a flat, sturdy

surface with the back of the unit awayfrom heating vents, radiators, curtainsand other objects that could restrict airintake.

• Secure the mask, connect the tubing, andprepare any accessories you might useprior to operation of the RemRest device.

It is recommended that the device be leftplugged in when not in use. This is especiallyhelpful for Tier 2 and 3. Tier 2 does not havea battery and therefore only “remembers”plugged in time with regards to time usedand time plugged in. Tier 3 has an internalbattery and therefore will “remember” all ofits times without being plugged in. However,it will save the battery if the unit remainsplugged in when not being used, i.e. duringthe day.

RemRest Tier 1There are two options to provide power tothe CPAP: AC or DC power.

1. For AC Power, plug one end of the ACpower cord into the AC inlet plug locatedon the back of the RemRest device. Plugthe other end into the wall socket. Go toStep 3.

2. If using the DC power cord with autoadapter for operation of the RemRest in amotor vehicle or recreational vehicle,insert the plug into the DC jack located onthe back of the CPAP and plug the otherend into the vehicle’s 12V DC outlet.

NOTEThe device will draw asmall amount of powerwhen plugged in but not “On”.
