  • Title: Immediate carbon monoxide estimates and self-reported smoking.
    Author: Fix AJ, Daughton DM, Kass I, Bell CW, Wass A.
    Journal: Percept Mot Skills; 1979 Oct; 49(2):675-8. PubMed ID: 514792.
    Abstract:
    Because carbon monoxide (CO) is an easily understood danger of cigarette smoking, new breath CO analyzers may be useful in cessation programs. Self-reported cigarette consumption and breath CO correlated .70 using a 90-sec. CO-determination method. Smokers averaging 17 daily cigarettes had average breath CO of 24 parts per million (ppm), falling to 7.71 ppm for smokers claiming at least 24-hr. abstinence. Corresponding carboxyhemoglobin (COHb) estimates were 4.34% (slightly above World Health Organization 4% safety limit) and 1.39%. Smoking clinics can use CO-monitoring devices for feedback or surveillance, although feedback would provide the most benefits for participants.
