1.2 Intended Use
The Palm O2 Oxygen Anal yzer is intended t o meas ure and dis pl a y the co ncentration of oxygen of o xygen in compressed breathin g air tanks intended for
scuba diving.
1.3 Device Description
The Pal m O 2 Ox yg en A nal yzer is desi gne d to b e ha nd held but ca n be t em po rarily placed in a fixed posi tion on a pole or s helf w i th o ption al br ac ket a tta chments as illustrated in Section 8.1. A remote sensor option is available which
makes th e Palm O2 m ore flexi ble and eas ier to use. Either wa y, it provi des
continuous, fast, reliable and accurate oxygen measurements.
The device utilizes an electrochemical galvanic fuel cell type oxygen sensor of
the type t hat is extens ivel y used to meas ure o xygen co nce ntratio ns f rom 0%
to 100% in gas streams. O xygen, the fuel f or this electroch emical transduc er,
diffus ing into the s ensor thr ough a g as permeabl e membra ne reacts ch emically at the sensi ng electro de to produ ce an elect rical curr ent o utput propo rtional to the ox yg en con ce ntra tio n in the g as phas e. T he s enso r h as an absolute zero meaning that when no oxygen is present to be chemically reacted
the LCD displays 00.0 oxygen.
The sensor’s signal output is linear over the entire range, remains virtually
constant over t he specif ied us eful li fe and drop s off sharply at the e nd. The
sensor itself requires no maintenance and is simply replaced at the end of its
useful l ife like a ba ttery. In asmuch as t he sensor i s a transdu cer in its own
right, its expected life is not affected by whether the analyzer is ON or OFF.
A batter y pow ered st ate-of -the-ar t mi cro-pr ocess or con verts t he s ensor’ s signal output representin g the parti al pressure of ox ygen in the gas str eam being
analyzed. The resulting oxygen reading is displayed by a large easy to read
backlit liquid crystal display (LCD) that has a resolution of 0.1% oxygen. The
microprocessor is controlled from a keypad and provides system diagnostics
and warning indicators for continuous monitoring that enhance both safety
and effectiveness.
Prior to shipment, every device is thoroughly tested at the factory and documented in the form of a Quality Control Certification that is included in the
Instructions for Use su pp lied with every de vice.

3 Safety Warnings
ALWAYS follo w the s tateme nts bel ow as they are ess enti al t o red uci ng
the risk of use error due to ergonomic features of the device or the
environment in which t he device is in te nded to be used.
Only trained personnel who have read, understand and agree to follow the
Inst ructions for Use should opera te the dev ice.
Retain the Instructions for Use for future reference.
Refer service needs to trained authorized personnel. Failure to do so may
cause the dev ice to fail and vo id the warranty.
Inspect the d e vi ce and a c c es s or i es befor e operati ng and ensure: ( a) there
is no evidence of physical damage; (b) the sensor (particularly the sensing
surface) and electrical connections are dry; and, (c) the sensor is installed
and is upstream from any h umidifying device for accura te calibration and
oxygen readings.
Calibrate: (a) with a known source of dry air or 100% oxygen before using
each da y o r af t er 8 hours of cont i n uo us use; ( b) whe n the t emperature or
pressure of the operating environment changes; (c) if the oxygen sensor
has been disconn ected and r econne cted; (d) af ter the battery or oxyge n
sensor has been replaced.
Sampling flowing gas: (a) install the optional accessories as shown in Sec-
tion 8.1 and (b) assure there is a tight fit between the components.
Sampling static, ambient or controlled atmospheres unscrew and remove
all components from the oxygen sensor.
Clean the device and accessories in accordance with Section 6.1.2.
Batter y repla cement Section 6.2: (a) repl ace the batteri es whe n the ‘ LO’
message is displayed on the LCD and (b) calibrate the analyzer after replacing the batteries.
Oxygen sensor installation or replacement Section 6.3 or 6.5: allow the
new sensor to stabilize for 15-20 minutes in ambient air before attempting
to calibrate.
Store the device by turning the power OFF and removing the batteries if
the device will not be operat ed for over thirty (3 0) days.
Attempt to repeat the procedure that caused a perceived malfunction and
refer to troubleshooting hints in Section 7 before concluding the device is
faulty. If in doubt, contact the manufacturer for assistance.
NEVER o perate the d evice in any m anner des cribed below doing so
may compromise the clinical condition or the safety of patients, users
or other persons.
If the reading is unstable or a malfunc tion is suspect ed.
After the ‘ERR’ or ‘LO’ messages are displayed on the LCD.
Near equipme nt capable of em i t ting hi gh le vel s of electr om agnetic radi a-
tion (EMI) or radio frequency interference (RFI).
Expose the device; particularly the LCD display or sensor to sources of
extreme heat, cold or excessive sunlight beyond the device’s storage
temperature range, refer to Section 8 for extended periods of time.
In a gas stream with a vacuum greater than 14” water column.
Immerse the device, oxygen sensor or optio nal coiled cable in any liquid .
Outside of the parameters specified in Section 8 particularly at flow rates
greater than 10 liters per min ute - the b ackpressure generated produces
erroneously high oxygen readings.
Calibrate: (a) with 20.9% ox ygen or room air with the intent of taking
oxygen measurements at oxygen levels above 30% oxygen; (b) in a
humidified gas stream or atmosphere; (c) without allowing a newly installed sensor to stabilize for 15-20 minutes in am bient air.
Attempt to sterilize, autoclave, liquid sterilize, immerse in any liquid or
expose the devic e or acces sories to steam, ethylene o xide or r adiation
sterilization.
Open the main com par tm e nt of t he d evice, ex cept to ch a nge t he i nt egral
oxygen sensor.
Open the oxygen sensor or probe the sensing surface, refer to Section 10
in the event the sensor should leak and someone comes in contact with
the electrolyte from inside the sensor.
Optional remote se nsor with a cable that a ppears wor n, torn or cr acked,
or, allow an excess length of cable near the patient’s head or neck; secure it to the bed rail or other suitable object to avoid the possibility of
strangulation.
Allow the devi ce or o x ygen sens or to be s ervi ced, re pair ed or alter e d by
anyone except trained personnel – failure to do so may endanger the
patient or damage the device rendering the warranty null and void.
