Introduction
The piCO+ Smokerlyzer® is a breath carbon
monoxide monitor intended for multipatient use by healthcare professionals
in smoking cessation programmes and
research. It can also be used as an
indicator of carbon monoxide poisoning in a
healthcare environment.
Carbon monoxide is a toxic, odourless,
colourless, tasteless gas. It is formed by
incomplete combustion of organic material
at high temperatures, with an insufcient
oxygen supply.
When inhaled, CO displaces oxygen in the
bloodstream to form carboxyhaemoglobin
(COHb). This starves the body tissues of
the oxygen vital to repair, regeneration
and general living. CO can remain in the
bloodstream for up to 24 hours, depending
on factors such as physical activity, gender,
and inhalation intensity. The half life is about
5 hours.
CO (ppm) and carboxyhaemoglobin
(%COHb) correlation:
Breath carbon monoxide is measured
in parts per million (ppm) and blood
carboxyhaemoglobin is measured in
percentages (%COHb). The two are
compatible and convertible: the CO reading
relates to gas in the lungs and on the
breath (i.e. the amount of poisonous CO
that has been inhaled), and the COHb
reading relates to the percentage of vital
oxygen that has been replaced in the
bloodstream. The piCO+ Smokerlyzer®
displays both measurements. Clinical
research has demonstrated that a useful
relationship between carbon monoxide and
carboxyhaemoglobin is obtained after a
short period of breath-holding.
The cut-off point between smoker and
non-smoker has been found to be 6ppm
CO. The piCO+ Smokerlyzer® denes a
non-smoker as 0-6ppm, a low-dependence
smoker as 7-15ppm and strongly addicted
smokers as over 15ppm.
The piCO+ Smokerlyzer® has been designed
so that it can be used with young smokers.
As their smoking habits and views are
generally different from adult smokers,
the cut-off points have changed: 0-4ppm
represents a non-smoker, 5-6ppm a light
or casual smoker, and over 7ppm a more
frequent young smoker.
Other cut-off points can be adopted as
well as smoking classication at higher
CO levels. The piCO+ has a third prole
which can be set by the user with COdata+
software to achieve complete exibility in
most circumstances

Warnings and maintenance
Warnings
People with lung disease or chest ailments
may not be able to achieve the 15-second
breath-hold. In such cases, the user should
inhale and hold their breath when the breath
test is started, and exhale, if necessary,
before the countdown has completed.
Steribreath mouthpieces should be replaced
after every use.
Hands should be washed regularly in
accordance with infection control practice.
Please do not attempt to modify the
equipment in any way or use accessories
not specied by the manufacturer. Any
attempt to do so will invalidate the warranty

that connection to other devices and
modications require evaluation to the
requirements of EN60601-1: 2006
Wipe the instrument and D-piece external
surfaces with a product specically
developed for this purpose. Bedfont
provides instrument cleansing wipes.
Cleaning
Routine maintenance
Calibrate the monitor using Bedfont 20ppm
CO in air calibration gas when prompted by
the calibration reminder on the piCO+ (see
page 12). Once calibration has been carried
out a reminder will reoccur in 6 months.
Replace batteries when indicated – battery
symbol either or .
Replace breath sampling
D-piece when prompted
by the unit every 30
days or if visibly soiled or
contaminated.
The D-piece cannot be
cleaned or sterilised.
Batteries

Ensure that two AA batteries are correctly
located in battery compartment.
• The single button controls all functions:
• One long press of the button (at least
three seconds) turns the unit on.
• A single click scrolls the pointer through
the list of options.
• A quick double click selects the required
option.
• One long press of the button (at least
three seconds) turns the unit off.
Press and hold the button
for three seconds until the
display becomes active.
Release the button. After a
10-second warm-up period,
during which a start-up
screen is displayed, the main
menu will appear.
If a is shown rather than the main
menu, it means that the instrument has
failed to set a fresh air zero during start-up.
This may be because the ambient air was
not clear of carbon monoxide. Ensure that
the instrument is in fresh air, then double
click the button to repeat the start-up test.
If it fails again, see ‘Troubleshooting’,
page 17.
When the pointer is opposite the picture of
an exhaling face, the piCO+ is ready to start
a breath test. The green LEDs will double
ash to indicate that the instrument is ready.
Operation
Attach a breath sampling D-piece and a
new SteribreathTM mouthpiece to the piCO+.
Check that all connections are pushed rmly
together.
To start a breath test, the patient should
inhale and hold their breath, then a quick
double click of the button will initiate a
15-second countdown display.
11
piCO+ Operating Manual
English
Ensure that the breath is held
throughout the countdown. An audio
beep will sound during the last three
seconds of the countdown. Once
the countdown reaches zero, exhale slowly
but gently into the mouthpiece. Aim to
empty the lungs as much as possible.
If the patient cannot hold their breath for
the full 15 seconds, they should commence
exhalation at a comfortable point, but
exhale completely.
The display will show a rising ppm value,
and an equivalent %COHb reading. The
coloured LEDs will illuminate, according to
the selected user prole.
The sounder will beep at an increasing
frequency, according to the concentration
of CO measured. To temporarily mute the
sounder, press the button once.
The highest level detected
during the exhalation will
remain on the display. The test
is complete when the pointer
and ‘return’ symbols appear at
the bottom of the display.
At this point, a single click of the button will
temporarily silence the sounder, if it is on.
To start another breath test, double click the
button to return to the main display. A new
mouthpiece should be used with every test.
Removing the D-piece between tests will
allow fresh air to purge the sensor. It is good
practice to wash your hands after removing
the D-piece.
If no further tests are required, the piCO+
should be turned off by holding the button
for three seconds. If left on, the piCO+ will
automatically turn off after ve minutes of
inactivity.

Troubleshooting
● If the unit fails to turn on properly, or if
either low battery symbols or
are shown, replace both AA batteries.
Ensure that the batteries are inserted
the correct way around, matching the
symbols moulded into the plastic.
● If a breath test on a non-smoker gives
an indication of CO being present, it
may indicate a high ambient level of
CO (possibly due to a faulty combustion
appliance or exhaust fumes), or
the effects of passive smoking. A
false reading can, under certain
circumstances, be caused by alcohol
on a person’s breath, or the presence of
hydrogen, which can be generated in the
human digestive system.
● If, after an attempted calibration with
20ppm CO gas, the display shows a
, the gas value was not within the
permitted limits. The achieved reading
is displayed underneath the . If the
value is much lower than 20ppm, there
may have been a problem with the
supply of gas from the cylinder during
the calibration process. If the displayed
value is much higher than 20ppm, it is
possible that the wrong concentration of
calibration gas is being used. In either
case, check the cylinder, connections
and ow rate before double clicking the
button to repeat the calibration process.

Q What is carbon monoxide?
A Carbon monoxide (CO) is a poisonous
gas that you cannot smell or see. When
a smoker inhales smoke from a cigarette,
CO is absorbed into their blood through
their lungs. CO is dangerous because
it binds to haemoglobin in red blood
cells about 200 times more readily
than oxygen, depriving the body of
vital oxygen.
Q What does a breath CO test show?
A It shows the amount of carbon monoxide
in a person’s breath (ppm CO), which is
a measure of blood carboxyhaemoglobin
(%COHb). It also acts as an indicator of
the possible level of around 4,000 toxic
substances in cigarette smoke, 60 of
which can cause cancer.
Q What does ppm and COHb mean?
A Parts per million; in this case, one part
of CO in one million parts of air (breath).
This might not seem like very much, but
ppm has a direct correlation with %COHb
(the percentage of CO combined with
haemoglobin in the blood).
Q How quickly does CO disappear from the
body when a person stops smoking?
A It takes about 5-6 hours to reduce the
original level by half. Usually, after a
maximum period of 48 hours, an exsmoker will have the same level of CO as
a non-smoker in the same environment.
Q How long after having a cigarette
should the test be conducted?
A After a minimum of 10 minutes.
Q What level of breath CO do you expect
to see?
A Clinical research has shown that the
popular guidelines are:
Q When is the best time to take a CO
reading?
A The best time to take a CO reading is as
late as possible in the day.
If a patient gives a reading of 20ppm (that
of a frequent adult smoker), it means that
their oxygen carrying capacity is reduced
by 5%. It also indicates a high level of
addiction to nicotine.

and a quotation for the repair, which will
include an authorisation form.
● If your monitor is still in warranty, Bedfont
will repair it and return it to you with an
‘Engineer’s Report’, free of charge. If
the monitor is found to simply require
calibrating, you will be charged a fee for
this service if you wish to proceed.
● If the monitor is out of warranty and
you wish to proceed with the repair or
calibration, complete the authorisation
form within the quotation, and ensure
that you include the ‘Ofcial Purchase
Order Number’. Return the unit to
Bedfont. Please contact the Customer
Repairs Department if you are unable
to supply an ‘Ofcial Purchase Order
Number’.
● If you choose not to proceed with the
repair, a handling fee will be charged.
Ensure that you return the completed
authorisation form with an ‘Ofcial
Purchase Order Number’.
● The equipment will be returned to you
as soon as Bedfont has received all
relevant paperwork. A carriage fee will
be charged if the monitor is no longer in
warranty.
