Abstract

Absorption spectra of human breath in 10 μm region were recorded by the use of intracavity laser photo-acoustic gas analyzer based on tunable waveguide CO₂ laser. Healthy persons and patients with various diseases were studied. For determination of CO₂ concentration in exhalation samples gas analyzer was calibrated by reference gaseous mixture CO₂-N₂. It was obtained that CO₂ concentration values in human breath of healthy persons are greater than that of patients with various diseases.
