Cigarette smoking is the single most preventable cause of morbidity and mortality, causing five million deaths worldwide each year. Exhaled carbon monoxide (CO) is a biological indicator to assess smoking status. Turn the CO Check ON by pressing by ON/OFF Power key. The subject should be encouraged to hold the breath for 15 seconds (CO Check pro). Press the select function key and the display will show the blow icon. Alternately, set the hold breath timer to desired number of seconds. The unit will count down the period during which the subject should hold the breath. When the period expires, the unit will display the blow icon. Then the carbon check pro is given exhaled CO levels and then calculate CO-HB percentage. CO PRO Check levels were assessed in a total of 205 subjects; 73 of them were active smokers 63 of them was passive smokers (62men; 1 woman) and 69 of them was non- smokers (28 men; 41 women). Active smokers were 35.6%, Passive Were 30.7% and non-smokers were 33.65%. The active smokers, the mean daily consumption of cigarettes was 5.458cigarettes/day. The mean exhaled CO level was 15.47ppm for healthy smokers and 1.65ppm for non-smokers and 4.5ppm for passive smokers. The mean exhaled CO level was significantly higher in healthy smokers than passive smokers and non-smokers. Our results shown that the optimal cut-off was 4.2ppm, giving 94% sensitivity and 85% specificity. There is a direct relationship between the smoking status of a given individual and the concentration of carboxyhaemoglobin (CO-Hb) in their blood. The estimation of (CO-Hb) is used to estimate the patient’s health status. The CO levels to ensure the patients’ health condition to wards CO poisoning risks, decreased morbidity and mortality due to smoking and CO poisoning.
