OxyWatch C20

1. General Description

Thank you for purchasing OxyWatch C20 pulse oximeter. This oximeter
can be used to measure your blood oxygen saturation (in % SpO ) and
2
your pulse rate. It should be used for spot monitoring only and not for
continuous monitoring.
The OxyWatch C20 Finger-Unit spot check oximeter is only for sports
and aviation use. It is ideal for use during sports activities, mountain
climbing and piloting airplanes. It is not intended to diagnosis any
medical condition or to be used in medical applications.

2. Package Contents

1. OxyWatch C20 Pulse Oximeter
2. Lanyard
3. User Manual
4. Carrying Pouch
5. 2 AAA Batteries

3. Precautions for Use

1. Read the manual carefully before use.
2. Pulse oximeters are sensitive to motion artifacts. Keep hands still
while taking a reading.
3. Pulse oximeters require sufficient blood flow to obtain proper readings.
Poor blood circulation can result in inaccurate readings. If your hands
are cold or you have poor circulation, warm your hands by rubbing
them together or use another method before attempting to obtain a
reading. A tourniquet, blood pressure cuff or other blood flow
hindrances may also result in inaccurate readings.
4. Fingernail polish or acrylic nails obstruct the light transmission and
may also result in inaccurate readings.
5. Your finger must be clean for a proper reading.
6. The pulse oximeter must be clean for a proper reading.
7. If a reading is difficult to obtain, switch to another finger or to the other hand.
8. There are a number of other conditions which may lead to an
inaccurate reading including but not limited to recent medical tests that
included an injection of dyes, use of arterial catheters, a weak pulse,
low levels of hemoglobin in the blood, low perfusion (the quality of
your pulse), elevated levels of dysfunctional hemoglobin, the strength
and type of light that you are in while using the pulse oximeter and the
existence of cell phones, radios, and fixed transmitters within certain
ranges of the pulse oximeter during use.
9. The pulse oximeter will not alert you if your readings are out of
normal range.
10. Explosion hazard: Do not use the pulse oximeter in an explosive
atmosphere.
11. The pulse oximeter has no SpO alarms; it is not for continuous
2
monitoring, as indicated by the symbol.
In addition to items described in the Precautions for Use, inaccurate
measurements may be caused by FACTORS INCLUDING BUT NOT
LIMITED TO:
1. Autoclaving, ethylene oxide sterilizing or immersing the sensors in liquid.
2. Significant levels of dysfunctional hemoglobin (such as carbonxy-
hemoglobin or methemoglobin).
3. Intravascular dyes such as indocyanine green or methylene blue.
4. SpO measurements may be adversely affected in the presence of
2
high ambient light such as direct sunlight. In bright light conditions,
cover the sensor area if necessary.
5. Excessive user movement.
6. High-frequency electrosurgical interference and defibrillators.
7. Venous pulsations.
8. The user has hypotension, severe vasoconstriction, severe anemia or
hypothermia.
9. Fingernail polish or false fingernails may cause inaccurate SpO
2
readings.
4. Battery Installation
1. Install two AAA batteries
into the battery compartment.
Match the plus (+) and minus
(-) signs in the compartment.
If the polarities are not
Slide Cover
matched, damage may be
caused to the oximeter.
2. Slide the battery door cover
horizontally along the arrow
as shown in the picture.
NOTE: Install the batteries in right polarity. Incorrect placement may
cause damage to the bracket.
NOTE: Remove the batteries if the pulse oximeter will not be used for
long periods of time.
3. The battery indicator symbol on the front panel display will light when
the battery voltage is too low for normal operation of the pulse oximeter.
Replace the batteries when indicator symbol lights.

5. Using the Oximeter

1. Open the clamp as shown in the picture.
2. Place one of your fingers into the rubber
opening of the pulse oximeter (your finger
should touch the bottom portion) before
releasing the clamp.
3. Press the switch button one time on front panel to turn the pulse oximeter on.
4. Keep your hands still for the reading. Do not shake your finger during
the test. It is recommended that you do not move your body while
taking a reading.
5. Read the data from the display screen.
6. There are four display modes. After turning on the pulse oximeter,
each time you press the power switch, the pulse oximeter will switch
to another display mode.
7. When you press the power switch for more than one second, the
brightness of the pulse oximeter will be changed by degrees. There
are 10 levels of brightness. The default level is level four.
8. When no signal or low signal is detected, the pulse oximeter will
power off automatically in 8 seconds.

6. Maintenance

1. Clean the pulse oximeter and sensor with a soft cloth dampened with
isopropyl alcohol. Do not pour or spray any liquids onto the pulse
oximeter. Do not allow any liquid to enter any openings in the device.
Allow the pulse oximeter to dry thoroughly before reusing.
(The rubber inside of the pulse oximeter is composed of medical
grade rubber. It is non-toxic and is not harmful to the skin.)
2. The pulse oximeter requires no routine calibration or maintenance
other than replacement of the batteries.
