Operating Manual

Introduction

Carbon monoxide is a toxic, odourless, colourless, tasteless gas. It is formed by incomplete combustion of organic material at high temperatures, with an insufficient 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

Intended use

®

defines 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 classification at higher

CO levels. The piCO

+

has a third profile which can be set by the user with COdata software to achieve complete flexibility in most circumstances

Operation

(continued)

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 profile.

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.

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 flow rate before double clicking the button to repeat the calibration process.

If, after a third repeated attempt to calibrate the instrument, the display shows a again, the unit will have to be reset or restored using the reset button located in the battery bay followed by the reset calibration procedure on page 13. If the problem persists, please return the unit to Bedfont or your local distributor for investigation and repair. In this case, the display shows a telephone and envelope symbol. The unit can be turned off by pressing the button for three seconds. It is possible to re-start the unit and use it with the previous calibration settings, or to attempt the complete calibration process again.

Frequently asked questions (FAQ)

Frequently asked questions about breath carbon monoxide (CO) monitoring in smoking cessation

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.

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.

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 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 How long after having a cigarette should the test be conducted?

A After a minimum of 10 minutes.

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.

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 What level of breath CO do you expect to see?

A Clinical research has shown that the popular guidelines are:
