1.0 SYSTEM OVERVIEW
1.1 Base Unit Description
The MaxO
2
ME is a handheld oxygen analyzer/monitor capable of measuring
the oxygen concentration from 0% to 100% in a sample gas. A MAX-550E
oxygen sensor outputs a voltage which is used by the MaxO
2
ME to determine
the concentration of oxygen based on a calibration at room air or 100%
oxygen. The MaxO
2
ME contains alarms that can be controlled by the user to
set a maximum or minimum allowable oxygen concentration.
»
Oxygen sensor of approximately 1,500,000 O
2
percent hours.
»
External probe with 10 ft., extendable cable and diverter fitting for standard 15 mm "T"
adapter.
»
Operation using 4 AA alkaline batteries (4 x 1.5 volts) for approximately 5000 hours of
performance with typical use.
»
Oxygen-specific, galvanic sensor that achieves 90% of final value in approximately 15
seconds at room temperature.
»
Self-diagnostic check of analog and microprocessor circuitry.
»
Low battery indication.
»
Calibration reminder timer that alerts the operator, using a calibration icon on the LCD
display, to perform a unit calibration.
»
Adjustable high-level and low-level alarming capability with flashing LED and audible
indication of alarm conditions.
»
Smart high-low alarm setting to help adjust alarm settings quickly
»
Back-light display with auto ambient light level detection.
»
Sleep Mode operation to extend battery life.
Indication for Use:
The MaxO
2
ME oxygen monitor is intended for continuous monitoring of the
concentration of oxygen being delivered to patients ranging from newborns to adults.
It can be used in the pre-hospital, hospital and sub-acute settings. The MaxO
2
ME is
not a life supporting device.
