About CO & COHb
What is Carbon Monoxide & Carboxyhemoglobin?
Carbon monoxide (CO) is a colorless, odorless gas produced through incomplete
combustion. CO is a poison that binds with hemoglobin, the oxygen-carrying molecule in
human blood. Because CO‟s affinity to bind with hemoglobin is 250 times greater than
oxygen, low airborne concentrations and long exposure times can result in substantial
carboxyhemoglobin (COHb) concentrations in the blood. COHb is CO bound to hemoglobin.
As COHb levels increase, less hemoglobin is available for the transport of oxygen. This lack
of oxygen-carrying capability, which is indicated by the increase in COHb, results in the
symptoms we associate with CO poisoning.
What are the Health Impacts
The acute health effects of CO exposure are well established. Mild exposure symptoms may
include headache, dizziness, decreased vigilance, decreased hand-eye coordination,
weakness, confusion, disorientation, lethargy, chest pain (in cardiac patients), nausea, and
visual disturbances. Greater or prolonged exposure can cause unconsciousness and death.
The severity of symptoms depends on the concentration of CO, length of exposure, and
degree of physical activity, as well as the state of health of the exposed individuals. People
who are exposed to high CO concentrations for long periods of time during strenuous
activity will reach the highest COHb levels.
Who are Sensitive Populations?
Age and general health may affect susceptibility to CO. Even low levels of CO can present a
health risk to susceptible individuals, such as persons with heart disease, sickle cell disease,
and anemia. Also, exposure to low levels of CO may harm the developing fetus.

Angina pectoris is chest pain associated with impaired oxygen flow to the heart and may
occur at COHb levels between 2.5 and 4.9 percent in cardiac patients. In healthy individuals
decreased vigilance, confusion and disorientation, behavioral, and central nervous system
effects occur at COHb levels between 4 and 6 percent. Remember that as symptoms of CO
poisoning increase, you may become confused and less capable of making decisions that
could save your life.
Smoking
Tobacco smoke, including second hand smoke, is a large source of CO in homes with
smokers. Smokers have higher COHb values than nonsmokers and exposure to secondary
tobacco smoke results in an increase in COHb values. Smokers generally have COHb values
of five to six percent. Nonsmokers have COHb levels of 0.5 percent, whereas nonsmokers
exposed to secondary tobacco smoke have been shown to have COHb levels in the two to
three percent range.

Introduction
Senko Co., Ltd. with brand name „SENKO‟ was established to provide
electrochemical (galvanic and amperometric) gas sensor, breath CO Monitor,
portable/fixed gas detector, gas monitoring system, and services that promote
worker‟s safety, prevent gas accidents, and enhance client‟s health
BMC-2000 can be used in smoking cessation programs by healthcare professionals.
And it also can be used as a non-invasive method to get %COHb in the patient‟s
blood and to screen CO poisoned patients by medical man.
The small size and light weight make the BMC-2000 ideal for hand held use. It is
mainly used in smoking cessation clinics; it is used for instructional purposes to
check on the client‟s progress and compliance.
BMC-2000 is based on an electrochemical gas sensor, which works through the
reaction of CO with an electrolyte at the electrode. This reaction generates an
electrical current proportional to CO concentration. Output from the sensor is
monitored by a microprocessor and converted to % carboxyhaemoglobin (%COHb).
Levels of %COHb in the blood are commonly caused by accidental smoke
inhalation/CO poisoning or cigarette smoking.
BMC-2000 has a countdown timer as an aid of timing the breath holding period
prior to exhalation

Operation and Calibraion
The operation of BMC-2000 is according to the below sequence.
Start –up
To install the 2 AA batteries, first open the battery cover by sliding it, clipping the battery
in place and closing the battery cover. Insert the mouthpiece adapter into the BMC-2000
and then connect a disposable mouthpiece to the mouthpiece adapter.
Press and hold the button until buzzer & LED become active.
LCD become active and displays it for 1 second
Display for 3 seconds
Main Mode
Arrow move: The arrow is moved up or down by pushing “UP”or “DOWN”button. The
arrow flickers per second.
Breath CO test
Enter Breath CO test mode then start Breath CO test
While a bar fills up black for 15 seconds, hold breath

The unit will beep out 3 times for the last 3 seconds
Blow into CO Breath Monitor (Display duration: 2sec)
Continue to blow (Display duration: 13sec)
After blowing out, CO Breath Monitor displays both
concentrations of CO & %COHb
Set up
Move the arrow down to „Set up‟and press enter
Move the arrow to „Age‟, „Sound‟, or „Language‟and press
enter button
„Menu‟returns to Main mode.
Set up I(Age)
If you are young or Pregnant then choose „Young, Preg‟
otherwise choose „Adult‟
„Back‟returns to Set up mode.

Set up II(Sound)
Set up II (Sound: on & off)
Set up II (Language)
Calibration
Calibration will remain stable to within 1% over one month and typically to within 5% over
6 months. Senko Co., Ltd. Supplies calibration gas (20ppm CO in air). Senko‟s Breath CO
monitor is recommended to recalibrate every 6 month.
Arrow move to down and press enter button
Zero calibration mode
Ensure that the breath CO monitor is surrounded by fresh air (0 ppm CO gas in fresh air).

Zero calibration (bar fills up black for 15 seconds)
The unit will beep out 3 times
If zero calibration is successful, “OK!”will be displayed. Otherwise, “Failure”will be
displayed. (If “Failure”happens see the troubleshooting section)
20ppm calibration mode
BMC-2000 is calibrated before shipping in a warehouse.
20ppm CO gas diluted in a fresh air is required for this calibration.
Screw the control valve and connect the flow indicator to the gas can as shown below.
Open control valve and allow the gas to flow at 0.5 liter/min. (flow indicator remains at
the line)
Press “enter”button. And press “yes”in below.
Allow the gas to flow through the CO monitor for about 1 minute to ensure accurate
calibration.
20ppm calibration (bar fill up black for 15 seconds)
The unit will beep out 3 times, store the new 20ppm calibration value.

If the 20ppm calibration is successful, “OK!”will be displayed. Otherwise, “Failure”will be
displayed. (If failure happens see the troubleshooting section)
Troubleshooting
If the unit fails to turn on properly, replace the 2 x AA batteries. (Battery lifetime is about
150 hours when the unit is working continuously)
After zero calibration, if the unit displays “Failure”, make a second attempt to the unit in
the fresh air. If the unit still displays “Failure”, the unit has to be returned to SENKO or its
distributor.
After 20ppm calibration, if the unit displays “Failure”, may be caused for the use of
incorrect calibration gas, first ensure that the concentration of calibration gas. Only 20ppm
CO gas should be used in this calibration. Second check the connections to the gas cylinder,
and the period of circulation of can gas. If there are no problems, try 20ppm calibration
again. If the unit still displays “Failure”, the unit has to be returned to SENKO or its
distributor.
Note
Ensure that the unit and can gas have stabilized at room temperature before calibration.
Use only the calibration gas produced from the certified company.
