OXYCHECK
FINGERTIP
PULSE OXIMETER
MODEL JB02017
OPERATOR MANUAL
GENERAL DESCRIPTION
The John Bunn
®
JB02017 OxyCheck Fingertip Pulse Oximeter
provides a simple way to spot-check users by combining the
sensor and monitor into one integrated, compact, easy to use
device. The oximeter measures pulse oxygen saturation (SpO
2
)
value, pulse rate value, and pulse strength. When a nger is
inserted into the sensor’s rubber cushion, the SpO
2
value auto-
matically displays. The pulse bar graph displays the user’s pulse
beat, and the bar graph’s height shows pulse strength. The
oximeter, which is powered by two AAA batteries, features a low-
battery indicator and powers off automatically in eight seconds
when not in use.
Product Accessories (Included)
1. One lanyard
2. Two AAA batteries
3. One protective cover
4. One operator manual
Principle of Measurement
Two beams of different wavelength (660 nm glow and 940 nm
near infrared light) are focused onto a human nail tip through a
clamping nger-type sensor. A measured signal obtained by a
photosensitive element, through processes of electronic circuits
and microprocessor, will be shown on the oximeter’s display.

INTENDED USE
The intended use of the OxyCheck Fingertip Pulse Oximeter is
the measurement and display of the functional oxygen satura-
tion of arterial hemoglobin (SpO
2
) and pulse rate (PR) of adults
and pediatric users in hospital, ambulatory, home, and EMS
(Emergency Medical Service) environments. The Pulse Oxim-
eter is intended for spot-checking these levels.
Contraindications (
WARNINGS):
• If you do not understand any part of these instructions,
contact a healthcare professional for direction in the use
of this product.
• This device is not intended for continuous monitoring.
• Do not use this device in an explosive atmosphere.
• Do not use this device in an MRI or CT environment.
INACCURATE MEASUREMENTS MAY BE CAUSED BY THE FOLLOWING:
• Autoclaving, ethylene oxide sterilizing, or immersing the
device in liquid
• Signicant levels of dysfunctional hemoglobins (such as
carbonxy- hemoglobin or methemoglobin)
• Intravascular dyes such as indocyanine green or methy-
lene blue
• High ambient light — shield the sensor area (with a surgi-
cal towel, or direct sunlight, for example) if necessary
• Excessive user movement
• High-frequency electrosurgical interference
• Venous pulsations
• Placement of a sensor on an extremity with a blood pres-
sure cuff, arterial catheter, or intravascular line
• User hypotension, severe vasoconstriction, severe ane-
mia, or hypothermia
• User cardiac arrest or shock
•
Improper nger placement, e.g. ngernail not facing upward
• Fingernail polish or false ngernails.
SAFETY — PRECAUTIONS FOR USE
WARNING: Indicates a potential hazard situation or
unsafe practice that, if not avoided, could result in death
or serious injury. WARNING statements follow:
Before use, carefully read the manual.
The pulse oximeter has no alarms. Do not use the pulse
oximeter in situations where alarms are required. It is not
for continuous monitoring.
The pulse oximeter is intended only as an adjunct in user
assessment. It must be used in conjunction with other
methods of assessing clinical signs and symptoms.
CAUTION: Indicates a potential hazard or unsafe prac-
tice that, if not avoided, could result in moderate or
minor personal injury. CAUTION statements follow:
Check the pulse oximeter sensor application site frequent-
ly to determine the positioning of the sensor and circula-
tion and skin sensitivity of the user.
Do not stretch the adhesive tape while applying the pulse
oximeter sensor. This may cause inaccurate readings or
skin blisters.
Prolonged use or the user’s condition may require chang-
ing the sensor site periodically. Change sensor site and
check skin integrity, circulatory status, and correct align-
ment at least every 4 hours.
s NOTICE: Indicates a potential hazard or unsafe practice
that, if not avoided, could result in product/property
damage.
SETUP
Battery Installation
1. Open battery compartment cover.
2.
Install two AAA batteries in battery compart-
ment, ensuring that polarities are correct.
3. Close battery compartment cover: Push cover horizontally
along the arrow as shown at right.
s NOTICE:
• Ensure battery polarities are correct, or the device could
be damaged.
Lanyard Installation
1.
Thread the thinner end of the lanyard through the oximeter
loop.
2. Thread the thicker end of the lanyard through the threaded
end, then pull it tightly.
OPERATION INSTRUCTIONS
1. Use isopropyl alcohol to clean the test nger and the rubber
inside the oximeter that touches the nger.
2. Place clamp over ngernail as shown
at right; insert nger, ngernail up as
shown.
3. Press button on front panel once. User’s nger and body
must remain still during measurement.
4. See display: the SpO
2
value automatically displays, the
pulse bar graph displays the pulse rate, and the bar graph’s
height shows the pulse strength.
MAINTENANCE AND STORAGE
s NOTICE:
• This device contains no serviceable parts. Do not disas-
semble.
• Remove the batteries if the oximeter will not be used for a
long period of time.
• Do not autoclave, sterilize with ethylene oxide, or im-
merse the device in liquid.
• See SPECIFICATIONS/Environmental Requirements for
operation and storage requirements. A wet ambience
could damage this product and shorten its lifetime.
• Recycle or dispose of this device and its used batteries in
observance of local regulations.
Info: Use isopropyl alcohol to clean the rubber (inside the
oximeter, that touches the nger) and the test nger before
and after each test. The rubber inside the oximeter is medi-
cal rubber, which has no toxins, and is not harmful to the
skin.
•
Replace the batteries when low battery indicator illuminates.
