WHO guidance states that to protect non-smoking, middle-aged, and elderly population groups with documented or
latent coronary artery disease from acute ischemic heart attacks, and to protect the foetuses of non-smoking
pregnant women from untoward hypoxic effects, a COHb level of 2.5% should not be exceeded. The following WHO
guideline values and periods of time-weighted average exposures have been determined in such a way that the COHb
level of 2.5% is not exceeded, even when a normal subject engages in light or moderate exercise:
100 mg/m³ (90 ppm) for 15 min.
60 mg/m³ (50 ppm) for 30 min.
30 mg/m³ (25 ppm) for 1 h.
10 mg/m³ (10 ppm) for 8 h.

Normal COHb levels
Under normal conditions, humans typically have low levels of COHb of between 0.3% and 0.7% present within the
body. These levels are considered neither beneficial nor harmful.
7.4
Tobacco smoking
Tobacco smokers are exposed to significant concentrations of CO. In cigarette smokers, the COHb concentration
varies between 5%-9%, while heavy cigar smokers may exceed 10%.
WARNING! Exposure to high levels of carbon monoxide can be fatal or cause permanent damage and disabilities.
WARNING! The device may not prevent the chronic effects of carbon monoxide exposure, and that the device will
not fully safeguard individuals at special risk.
