Operation

For accurate results the BabyCO meter 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 BabyCO meter and then insert a disposable

mouthpiece into the adapter. Turn the unit on by pushing the slide

switch to the middle position (CO). The display will show the

software version number momentarily whilst correction for ambient

levels is executed. During this time the unit must not be exposed to

any source of CO. The buzzer will then sound and the display will

change to:

BLOW

Upon hearing the buzzer instruct the subject to inspire fully and hold

their breath for as long as is comfortable. The breath-holding period

is recommended to allow time for equilibration of alveolar gas.

The subject should then seal their lips around the mouthpiece and

exhale slowly and fully.

After emptying the lungs completely the display will show the

expired CO concentration in the expired air in parts per million

(ppm):
