Paper Abstract

Results on tunable diode laser spectroscopy applications in analysis of human expiration are presented. Carbon monoxide concentrations in exhaled air of several non-smoking adults were measured with high sensitivity. Obtained CO contents slightly exceed atmosphere level and correlate with it. Simultaneous measurements of carbon monoxide and carbon dioxide were carried out using single diode laser generated at 4.7 microns. Dependences of their concentration in exhaled air on breath-holding time were investigated.
