response, maximum reliability and stable performance. The OM-25A is designed primarily
for spot-checking oxygen concentration delivered by oxygen concentrator units, however,
its internal sensor and adaptable sampling port make it suitable for a wide variety of oxygen
analysis applications.

WARNINGS
FAILURE TO COMPLY WITH THESE WARNINGS AND CAUTIONS COULD RESULT IN
INSTRUMENT DAMAGE AND POSSIBLY JEOPARDIZE THE WELL BEING OF THE PATIENT
AND/OR HEALTH CARE PROFESSIONAL.
»
The sensor of the MAXO2 Oxygen Analyzer (MAXO2) has been tested with various
anesthesia gases including Nitrous oxide, Halothane, Isourane, Enurane, Sevourane
and Desurane and found to have acceptable low interferance, the device in its entirety
(including electronics) is not suitable for use in the presense of a ammable anesthetic
mixture. Only the threaded sensor face and sample inlet connection may be allowed to
contact such a gas mixture.
»
To avoid explosion, do not operate the oxygen analyzer in the presence of ammable
anesthetics or in an atmosphere of explosive gases. Operating the oxygen analyzer in
ammable or explosive atmospheres may result in re or explosion.
»
Never allow an excess length tubing near the patient’s head or neck, as such could result in
strangulation.
»
Before use, all individuals who will be using the MAXO2 must become thoroughly familiar
with the information contained in this Operation Manual. Strict adherance to the operating
instructions is necessary for safe effective product performance. This product will perform
only as designed if installed and operated in accordance with the manufacturer’s operating
instructions.
»
Use only genuine Maxtec accessories and replacement parts. Failure to do so may
seriously impair the monitor’s performance. Repair or alteration of the MAXO2 beyond
the scope of the maintenance instructions or by anyone other than an authorized Maxtec
service person could cause the product to fail to perform as designed.
»
Calibrate the MAXO2 weekly when in operation and if enviromental conditions change
signicantly. (ie, Temperature, Humidity, Barometric Pressure. --- Refer to Calibration
section of this manual).
»
Use of the MAXO2 near devices that generate electrical elds may cause erratic readings.
»
If the MAXO2 is ever exposed to liquids (from spills or immersion) or to any other physical
abuse, turn the instrument OFF and then ON. This will allow the unit to go through its self
test and make sure everything is operating correctly.
»
Never autoclave, immerse or expose the MAXO2 (including sensor) to high temperatures
(>70°C). Never expose the device to pressure, irradiation vacuum, steam, or chemicals.
»
To protect the unit from potential leaky battery damage always remove batteries when
the unit is going to be stored (not in use for 1 month) and replace dead batteries with
recognized name brand AA Alkaline batteries. Do not use rechargeable batteries.
»
This device does not contain automatic barometric pressure compensation.
»
