Sigara bağımlılarında solunum havasında karbonmonoksit düzeyleri

Amaç: Sigara içme durumunun belirlenmesinde birçok yöntem vardır. Solunumla verilen havada karbonmonoksit ölçümü geçerli ve uygulanması elverişli bir yöntemdir. Bu çalışmanın amacı sigara içenlerle içmeyenler arasında ayırım yapmada nefes karbonmonoksit konsantrasyonlarının kesim noktasını saptamaktır. Yöntem: Elle taşınan bir cihaz (Micro CO) solunumla verilen havadaki karbonmonoksit konsantrasyonlarını ölçmekte kullanıldı. 31 sigara içicisinin ve 30 sigara içmeyen kişinin nefes karbonmonoksit düzeyleri ölçüldü.Bulgular: Sigara içmeyenler grubunda karbonmonoksit konsantrasyonları 0-5 ppm (milyonda partikül), sigara içenler grubunda 5-70 ppm olarak saptandı. Sigara içenlerin ortalama karbonmonoksit konsantrasyonu 27.8 + 17.0 ppm, sigara içmeyenlerin 1.7 +1.0 ppm’ydi (p

Carbon monoxide levels in the expired air of smokers

Objective: There are a variety of independent methods of estimating smoking status. The measurement of carbon monoxide in the expired air has proven to be a reliable and convenient method. The purpose of this study is to determine the optimal breath carbon monoxide concentration cut-off level to distinguish actual smokers from nonsmokers. Method: A hand held breath analyzer (Micro CO) was used to measure expired-air carbon-monoxide concentrations. Breath carbon monoxide levels were measured in 31 smokers and 30 nonsmokers. Results: The range of carbon monoxide concentrations obtained was 0-5 parts per million (ppm) in the non-smoking group and 5-70 ppm in the smoking group. Smokers had a mean breath carbon monoxide concentration of 27.8 + 17.0 ppm and non-smokers had a mean of 1.7 +1.0 ppm (p
