Cigarette Consumption And Co Measurements - CareFusion Smoke Check Manuel D'utilisation

Cigarette Consumption and CO Measurements

The Smoke Check meter provides a simple screening test for cigarette
consumption for use in anti-smoking clinics and all smoking cessation
programs.
Measurement of expired CO has been well validated as an indirect
measure of cigarette consumption and is widely used in smoking
cessation programs.
Typical values for expired CO in smokers, together with the alarm light
status, are given below:
CO (ppm) Cigarette consumption
0 - 6 Non smoker
7 - 10 Light smoker
11 - 20 Heavy smoker
20+ Very heavy smoker
Please note that some urban areas may have high environmental
levels of CO. This can cause a rise in exhaled CO of a few ppm above
that which is normally present on the breath. In these cases it is
possible for a non-smoker to appear at the bottom of the "light
smoker" range (7 - 10 ppm).
