SAFETY SUMMARY

The following recommendations are made for
the safe and proper use of the Invacare Check
O2 Plus Hand-Held Analyzer:

CAUTION

“Caution: Federal law restricts this device to
sale by or on order of a physician, or any other
practitioner licensed by the law of the State
in which he practices to use or order the use
of this device.”

DO NOT expose any port of the analyzer to
any pressure greater than 20 PSI or damage
may result to internal components.

DO NOT use the analyzer on pure oxygen from
high pressure cylinders or liquid systems.

DO NOT use the Invacare Check O

2

Plus
Hand-Held Analyzer on any gas stream that
is humidified. Use of the analyzer with water
vapor can cause erroneous readings and in­ternal damage.

INTENDED USE

NOTE: The Invacare Check O2 Plus Hand-Held Ana­lyzer is designed and calibrated for use in measuring
unhumidified output gas of an oxygen concentrator ONLY.

NOTE: The analyzer is not for continuous monitoring
of patient gases.

NOTE: There are no user serviceable parts inside the
analyzer. Field calibration of the unit is not required.

NOTE: When using the analyzer after storage in either
extremely hot or cold conditions, allow the gas being
measured to flow through the analyzer for one (1) minute
to bring the internal sensor up to the gas stream tem­perature.

INSTRUCTIONS FOR USE (FIGURE 1)

`

1. Press the ON (

I

) button. The LCD display should

come on.

NOTE:The analyzer automatically shuts off after approxi­mately two (2) minutes of operation. This helps save bat­tery life.

2. The display will show “FLO” for approximately two (2)
seconds and then switch to readings in L/min.

3. If no reading is displayed or if display is erratic or fro­zen, refer to the troubleshooting section of this instruc­tion sheet.

4. In order to measure oxygen concentration or
flow rate, connect the analyzer’s FLOW/CON­CENTRATION inlet with a piece of ¼-inch (I.D.)
crushproof tubing to the outlet fitting of the gas
source to be measured.

5. In order to measure pressure, connect the analyzer’s
PRESSURE inlet with a piece of ¼-inch (I.D.)
crushproof tubing to the outlet fitting of the gas source
to be measured.

6. Pressing the FUNCTION ( ) button will toggle
the analyzer through its various detecting functions.

DISPLAY MEASURES VALUE

FLO Flow rate Liters per minute
O2 Oxygen concentration Percentage oxygen

HPA Pressure KiloPascals

WARNING

DO NOT install this equipment without first read­ing and understanding this instruction sheet. If
you are unable to understand these instructions,
contact a healthcare professional, dealer or
technical personnel if applicable before at­tempting to install this equipment - otherwise,
injury or damage may occur.

Oxygen rapidly accelerates combustion:

DO NOT smoke while using oxygen.

DO NOT use oxygen in the presence of flames,
sparks, or glowing objects.

Ensure that all items are properly and securely
installed.

NOTE: The Invacare Check O2 Plus Hand-Held Analyzer
can be used to measure the performance of an oxygen
concentrator from its outlet fitting, or any concentrator ac­cessory such as the Invacare Remote Flowmeter or Pe­diatric Flowmeter. However, Invacare does NOT recom­mend using the Invacare Check O

2

Plus Hand-Held Ana­lyzer to measure flow rates below 1 L/min. See product
specifications.

NOTE: The concentrator output gas, measured from the
concentrator outlet fitting or from a concentrator accessory
outlet fitting,must NOT contain humidified gas. Disconnect
any humidifier bottle before taking any readings to prevent
erroneous readings and damage to the internal flow sen­sor. Be sure to reconnect any required humidifier bottle
before returning any equipment to patient use.
