Prototype Device for Measuring Carbon Monoxide Levels in Human Exhalation

The aim of the work is to create on the basis of a modern component base a prototype device for non-invasive control over the condition of those poisoned by carbon monoxide or smoking in the conditions of mobile ambulance, fire and rescue operations and intensive care. It is shown that • concentration of CO in the exhalation of a person who does not smoke is in the range of 1 ÷ 2 ppm, which corresponds to the values given in the literature [3]; • graph of the dependence of the sensor response (in ppm) on the time of measurement in the atmosphere of one deep exhalation of a person after 5 minutes after smoking a cigarette has well-defined maxima, and the concentration of CO in exhalation is 13 ppm higher than before smoking.
