INDICATIONS FOR USE
SAROS oxygen system is indicated for the administration of supplemental oxygen. The device is not intended for life support nor does it
provide any patient monitoring capabilities. The SAROS can be used in the Military Medical Service that is operationally used for medical
assemblages, such as the Expeditionary Medical Support (EMEDS) and En-Route Patient Staging System (ERPSS), in deployed scenarios,
including wartime operations, deterrence and humanitarian and contingency operations.
The SAROS is used by patients suffering from discomfort due to ailments which affect the efciency of one’s lungs to transfer the oxygen
in air to their bloodstream. The device will be operated by a trained medical technician or clinician with a working knowledge of oxygen
concentrators. A physician has prescribed a specic oxygen ow setting to meet an individual’s needs. Oxygen ow should be adjusted only
under the direction of a physician.
The SAROS uses a vacuum pressure adsorbent process to separate oxygen from the air and deliver oxygen rich gas to a patient through a
nasal cannula.
WARNING: FEDERAL U.S. LAW RESTRICTS THIS DEVICE TO SALE BY OR ON THE ORDER OF A PHYSICIAN.
INDICATIONS
WARNING: IN CERTAIN CIRCUMSTANCES, THE USE OF NON-PRESCRIBED OXYGEN CAN BE HAZARDOUS. THIS
DEVICE SHOULD ONLY BE USED UNDER THE DIRECTION OF A PHYSICIAN OR QUALIFIED CLINICIAN.
NOT FOR USE IN THE PRESENCE OF FLAMMABLE ANESTHETICS.
AS WITH ANY ELECTRICALLY POWERED DEVICE, THE USER MAY EXPERIENCE PERIODS OF NON-OPERATION AS A RESULT OF
ELECTRICAL POWER INTERRUPTION, OR THE NEED TO HAVE THE SAROS SERVICED BY A QUALIFIED TECHNICIAN. SAROS IS
NOT APPROPRIATE FOR ANY PATIENT WHO WOULD EXPERIENCE ADVERSE HEALTH CONSEQUENCES AS THE RESULT OF SUCH
TEMPORARY INTERRUPTION.
USE OF AN OXYGEN MASK IS CONTRAINDICATED DUE TO THE POSSIBILITY OF REBREATHING EXHALED CARBON DIOXIDE.
WARNING: EXHAUST GAS MAY REACH HIGH TEMPERATURES DURING NORMAL OPERATIONS. USE CAUTION TO AVOID
TOUCHING THE EXHAUST PORT OF THE SAROS WHILE IN USE.
WARNING: THERE IS A RISK OF FIRE ASSOCIATED WITH OXYGEN THERAPY. DO NOT USE CONCENTRATOR OR ACCESSORIES
NEAR SPARKS OR OPEN FLAMES.
WARNING: SMOKING DURING OXYGEN THERAPY IS DANGEROUS AND IS LIKELY TO RESULT IN SERIOUS INJURY OR DEATH OF
THE PATIENT AND OTHERS FROM FIRE.
WARNING: OPEN FLAMES DURING OXYGEN THERAPY ARE DANGEROUS AND IS LIKELY TO RESULT IN FIRE OR DEATH. DO NOT
ALLOW OPEN FLAMES WITHIN 2 METERS OF THE OXYGEN CONCENTRATOR OR ANY OXYGEN CARRYING ACCESSORIES.
WARNING: SMOKING DURING OXYGEN THERAPY IS DANGEROUS AND IS LIKELY TO RESULT IN FACIAL BURNS OR DEATH. DO
NOT ALLOW SMOKING WITHIN THE SAME ROOM WHERE THE OXYGEN CONCENTRATOR OF ANY OXYGEN CARRYING ACCES-
SORIES ARE LOCATED. IF YOU INTEND TO SMOKE, YOU MUST ALWAYS TURN THE OXYGEN CONCENTRATOR OFF, REMOVE THE
CANNULA AND LEAVE THE ROOM WHERE EITHER THE CANNULA OR MASK OR THE OXYGEN CONCENTRATOR IS LOCATED. IF
UNABLE TO LEAVE THE ROOM, YOU MUST WAIT 10 MINUTES AFTER YOU HAVE TURNED THE OXYGEN CONCENTRATOR OFF
BEFORE SMOKING.
NOTE: Auditory alarms may not be heard in noisy environments and/or in tactical mode. Care providers must rely on visual indications to deter-
mine if there are any alarms or other system malfunctions. Care providers should monitor the SAROS for any alarm conditions.

CONTRAINDICATIONS
SAFETY GUIDELINES
These are Warnings and Cautions that apply to hazards or unsafe practices that could result in serious injury or property damage.
WARNING: FEDERAL U.S. LAW RESTRICTS THIS DEVICE TO SALE BY OR ON THE ORDER OF A PHYSICIAN.
WARNING: DO NOT USE SAROS IF IT HAS A DAMAGED POWER CORD OR PLUG.
WARNING: DO NOT DROP OR INSERT ANY OBJECTS INTO ANY OPENING ON THE DEVICE.
WARNING: DO NOT BLOCK THE AIR INLET OR THE EXHAUST VENT OF THE SAROS WHEN IT IS ON A SOFT SURFACE, SUCH AS A
LITTER, BED, CHAIR, CARPET, COUCH OR VEHICLE SEAT.
WARNING: DO NOT COVER THE DEVICE WITH A BLANKET, TOWEL OR SHEET, ETC.
WARNING: DO NOT STORE THE SAROS WITH THE BATTERY INSTALLED IN THE UNIT.
WARNING: DO NOT REMOVE THE COVER.THERE ARE NO USER-SERVICEABLE PARTS INSIDE THE DEVICE. ONLY QUALIFIED
SERVICE PERSONNEL SHOULD REMOVE THE COVER OF THE DEVICE.
WARNING: DO NOT MODIFY THIS EQUIPMENT WITHOUT AUTHORIZATION OF THE MANUFACTURER.
WARNING: DO NOT OPERATE THE DEVICE, COMPONENTS OR ACCESSORIES ON WET SURFACES OR IN STANDING WATER AND
DO NOT SUBMERSE IN WATER.
WARNING: GERIATRIC, PAEDIATRIC OR ANY OTHER PATIENT UNABLE TO COMMUNICATE DISCOMFORT CAN REQUIRE AD-
DITIONAL MONITORING AND OR A DISTRIBUTED ALARM SYSTEM TO CONVEY THE INFORMATION ABOUT THE DISCOMFORT
AND OR THE MEDICAL URGENCY TO THE RESPONSIBLE CARE GIVER TO AVOID HARM.
WARNING: OXYGEN MAKES IT EASIER FOR A FIRE TO START AND SPREAD. DO NOT LEAVE THE NASAL CANNULA OR MASK
ON BED COVERINGS OR CHAIR CUSHIONS, IF THE OXYGEN CONCENTRATOR IS TURNED ON, BUT NOT IN USE; THE OXYGEN
WILL MAKE THE MATERIALS FLAMMABLE. TURN THE OXYGEN CONCENTRATOR OFF WHEN NOT IN USE TO PREVENT OXYGEN
ENRICHMENT.
WARNING: IF YOU FEEL DISCOMFORT OR ARE EXPERIENCING A MEDICAL EMERGENCY WHILE UNDERGOING OXYGEN
THERAPY, SEEK MEDICAL ASSISTANCE IMMEDIATELY TO AVOID HARM.
WARNING: WIND OR STRONG DRAUGHTS, INCLUDING AN OPEN WINDOW OR FAN, CAN ADVERSELY AFFECT ACCURATE
DELIVERY OF OXYGEN THERAPY.
WARNING: THE SETTINGS OF OTHER MODELS OR BRANDS OF OXYGEN THERAPY EQUIPMENT DO NOT CORRESPOND WITH
THE SETTINGS OF THE SAROS MODEL 4000.
WARNING: IN THE EVENT THERE IS A SERIOUS INCIDENT OCCURRING WITH THIS DEVICE, THE USER SHOULD IMMEDIATELY
REPORT THE INCIDENT TO THE PROVIDER AND/OR THE MANUFACTURER. A SERIOUS INCIDENT IS DEFINED AS AN INJURY,
DEATH, OR POTENTIAL TO CAUSE INJURY/DEATH SHOULD THERE BE A REOCCURRENCE OF THE INCIDENT. THE USER CAN
ALSO REPORT THE INCIDENT TO THE COMPETENT AUTHORITY IN THE COUNTRY WHERE THE INCIDENT OCCURRED.
WARNING: THIS PRODUCT CAN EXPOSE YOU TO CHEMICALS INCLUDING NICKEL, WHICH IS KNOWN TO THE STATE OF CALI-
FORNIA TO CAUSE CANCER. FOR MORE INFORMATION, GO TO WWW.P65WARNINGS.CA.GOV.

Operator Manual
1.0 INTRODUCTION
1.1 GENERAL INFORMATION
This manual will familiarize you with information regarding the SAROS Oxygen System, Model 4000.
INTRODUCTION
The SAROS Oxygen System, Model 4000 with autoSAT® Technology (hereafter referred to as SAROS) is a portable medical device used to
extract oxygen from the atmosphere, concentrate it to greater than 90% and ow it through the oxygen outlet port. The device will operate in
Continuous ow or Pulse ow modes. In Continuous Flow Mode the oxygen is provided at a constant ow rate of 1, 2, or 3 LPM. In Pulse
ow Mode, oxygen is supplied in a bolus at the beginning of each inspiration, providing a selectable range setting of ow between 16 ml and
96 ml, in increments of 16 ml.
SAROS is BTP (Body, Temperature, and Pressure) compensated. It delivers oxygen by accounting for difference between ambient conditions
and those found in the patient’s lungs (37°C).
SAROS operates from external AC power, 24VDC or from a rechargeable Battery. The system includes a “Smart Battery” charger that
recharges the Battery whenever the SAROS is connected to external power. The system monitors and controls both the power source and the
Battery Charger.
SAROS has a recommended ve minute warm up/stabilization period.
INTENDED USE
The CAIRE SAROS oxygen system is intended for the administration of supplemental oxygen. The device is not intended for life support nor
does it provide any patient monitoring capabilities.
WARNING: THE BATTERY MAY EXPLODE AND CAUSE POTENTIAL INJURY IF EXPOSED TO A FIRE, OR DISPOSED OF IN A FIRE.
WARNING: EXPOSING THE BATTERY TO WATER OR OTHER LIQUIDS MAY CAUSE PERSONAL INJURY.
CAUTION: DO NOT EXPOSE THE BATTERY TO TEMPERATURES ABOVE 140° F (60°C), SUCH AS IN A VEHICLE PARKED IN THE
SUN ON A HOT DAY.
CAUTION: IT IS NOT RECOMMENDED THAT THE BATTERY IS CHARGED BELOW 41° F (5° C) OR ABOVE 104° F (40° C).
CAUTION: ONLY USE THE BATTERY FOR ITS INTENDED PURPOSE.
CAUTION: PUSH LOCKING/UNLOCKING BUTTON BEFORE BATTERY INSTALLATION.
