14. oker pi Smoker Q Ifa smoker cuts down will this reduce breath CO by an equivalent amount A Probably not Asmoker may smoke fewer cigarettes but will require the same amount of nicotine Therefore they may smoke a smaller number but will smoke more aggressively and inhale more smoke and CO than expected However this effect can be offset by the use of nicotine replacement therapy NRT which reduces a person s craving for nicotine and how much smoke they inhale Q Is it necessary to hold the breath before taking the test A Not absolutely necessary Clinical research has shown that an optimum period of 15 seconds breath hold is required to get the best correlation with COHb Less than this will depress the breath CO reading However as long as the person is encouraged to exhale completely an end tidal breath sample will give a good enough indication Q Do cigars and pipes give low readings A No on the contrary an inhaled puff of pipe or cigar smoke is much more concentrated and will give surprisingly high COHb readings Marijuana smoking especially when mixed with tobacco will also elevate blood CO Q Why do non smokers sometimes give higher than expected readings A This could be for several reasons They have been exposed to high ambient levels of CO For example at home or in the car It could be useful to check other family members in order to eliminate possible chronic CO poisoning Certain
