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.
A PHYSICIAN HAS PRESCRIBED A SPECIFIC OXYGEN FLOW SETTING TO MEET AN INDIVIDUAL’S NEEDS.
OXYGEN FLOW SETTINGS SHOULD BE ADJUSTED ONLY UNDER THE DIRECTION OF A PHYSICIAN.
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 CONSE-
QUENCES 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.
NOTE: Auditory alarms may not be heard in noisy environments and/or in tactical mode. Care providers must rely on visual indications
to determine 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.

Operator & Service Manual
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.
CAUTION: Indicates a hazardous situation that, if not avoided, could result in minor or moderate injury.
CAUTION: Keep SAROS and the power cord away from hot surfaces or open flames.
CAUTION: SAROS should be located in a well-ventilated area to allow for adequate air intake.
CAUTION: Avoid the intake of airborne pollutants, smoke and fumes.
CAUTION: ONLY use this device with accessories specified by, or recommended by CAIRE Inc.
CAUTION: If SAROS has been dropped, damaged or exposed to water, please contact a qualified technician for
inspection or possible repair of the device.
CAUTION: When using SAROS in any vehicle, be sure it is properly secured, belted or restrained.
CAUTION: LOCATE OXYGEN SUPPLY TUBING AND ALL POWER CORDS IN A MANNER TO PREVENT TRIPPING
HAZARDS.
CAUTION: DO NOT PLACE THE SAROS IN A SMALL, ENCLOSED SPACE, SUCH AS A BATHROOM, CLOSET, BAG OR BOX
WITH THE OXYGEN CANNULA OR TUBING LEADING OUT OF THE ENCLOSED SPACE.
CAUTION: DO NOT EXPOSE THE DEVICE TO TEMPERATURES OUTSIDE OF THE SPECIFIED RANGE OF OPERATING OR
STORAGE TEMPERATURES AS THIS MAY DAMAGE THE DEVICE.
NOTE: THIS DEVICE DOES EXHAUST NITROGEN GAS. HOWEVER, THIS EXHAUST IS NOT SUFFICIENT TO DISPLACE OXYGEN IN THE OP-
ERATING ENVIRONMENT. NO ADDITIONAL SAFETY PRECAUTIONS NEED TO BE TAKEN TO ACCOUNT FOR THE NITROGEN EXHAUST.
NOTE: PROTECT ELECTRICAL POWER CORDS FROM SHARP EDGES OR ELECTRICAL SHOCK AND SERIOUS PHYSICAL INJURY MAY
OCCUR.
NOTE: ONLY USE THE CAIRE INC. SUPPLIED AC POWER ADAPTER AND 24 VDC CABLE WITH THE SAROS. USE OF ANY OTHER AC POWER
ADAPTER OR DC CABLE MAY BE HAZARDOUS, CAUSE SERIOUS DAMAGE TO THE SAROS AND WILL VOID THE WARRANTY.
NOTE: AVAILABILITY OF AN ALTERNATE, OR BACK-UP, SOURCE OF SUPPLEMENTAL OXYGEN IS RECOMMENDED IN CASE OF A POWER
OUTAGE OR A MECHANICAL FAILURE OF THE DEVICE.

BATTERY SAFETY
WARNING: DO NOT DISASSEMBLE, PUNCTURE, OR CRUSH THE BATTERY. BATTERY ELECTROLYTES MAY BE TOXIC IF
SWALLOWED AND CAN BE HARMFUL TO SKIN AND EYES. KEEP THE BATTERY AWAY FROM CHILDREN.
WARNING: DO NOT SHORT-CIRCUIT THE BATTERY’S METAL CONTACTS WITH METALLIC OBJECTS, SUCH AS KEYS OR
COINS. THIS MAY CAUSE SPARKS OR EXCESSIVE HEAT TO BE GENERATED.
WARNING: USE OF A DAMAGED BATTERY MAY CAUSE PERSONAL INJURY.
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.
