Intended Use

The Smoke Check is intended to measure the concentration of carbon
monoxide, (CO) on the breath. It is used in smoking cessation clinics
as a motivational aid, GP's surgeries, accident and emergency
departments, and by the fire-fighting services.
The Smoke Check is designed for use by clinicians and health care
professionals.

Operation

For accurate results the Smoke Check should be used at room
temperature. If the instrument has been stored in cool or hot
conditions then allow time to reach room temperature prior to use.
Install the PP3 battery by sliding open the battery cover, clipping the
battery in place and replacing the cover. Insert the mouthpiece
adapter into the Smoke Check meter and then insert a disposable
cardboard mouthpiece into the adapter. If possible, the subject should
rinse their mouth with clean water prior to performing a test. Do not
use mouthwash, as the readings will be affected.
To obtain an accurate reading from a sample of alveolar gas the
patient should inspire and hold their breath for 20 seconds before
expiring slowly and fully through the mouthpiece. As an aid to timing
the breath holding period, a buzzer will sound 20 seconds after the
unit is turned on. However the instrument may be used any time after
the first 12 seconds when the auto-zero has been performed.
Turn the unit on by pushing the central slide switch up and the three
coloured lights will illuminate momentarily together with all the display
legends:
