USE OF MULTISENSOR GAZOANALIZATOR FOR THESTING OF AIR COMPOSITION DURING HUMAN BREATHING

Introduction. During the oxidation of products resulting from the long chain of chemical transformations of carbohydrates, fats and proteins, carbon dioxide as a marker of metabolic processes in the body is emitted. The ratio of carbon dioxide emitted from the body to the volume of oxygen absorbed during the same time a determination of the respiratory coefficient can be used. There are a number of methods for determining this coefficient, but they provide only general recommendations for the assessment of metabolic processes that do not take into account the personal characteristics of the organism, which follow in determining the parameters of respiration. Therefore, an urgent task is to create an information technology that, using a multisensory gas analyzer and a non-invasive method, will make it possible to measure the components of a gas mixture exhaled by a person to identify deviations in the gas exchange system.

Purpose. The purpose of the article is to create an integrated IT for non-invasive determination of the gas exchange coefficient using a multi-touch gas analyzer and the calculation of the state of the respiratory system for the timely detection of deviations in the gas exchange system.

Methods. IT, which using the method of non-invasive determination of the gas exchange coefficient (CGE) using a multi-touch gas analyzer allows you to measure the components of the gas mixture exhaled by a person was proposed. The method of calculating indicators of the state of the respiratory system timely detection of deviations in the gas exchange system is allows. This IT, taking into account the relationship of the respiratory coefficient with the caloric oxygen coefficient, to create a method for determining the type of dietary nutrition in the treatment of various diseases can be used.

Results. In an experimental study that was carried out using an MGA device using the developed non-invasive technique, measurements of the components of the gas mixture of exhaled air and the subsequent calculation of the CGE were made. The results of a study of a group of 45 healthy individuals of different age and sex that the obtained CGE for the entire group was within 0.838 – 0.882, which corresponds to the norm of the average adult are showed.

Conclusions. A method of non-invasive determination of the gas exchange coefficient using a multi-touch gas analyzer is proposed. The measurement features of the components of the gas mixture exhaled by man, and a method was developed for calculating indicators of the state of the respiratory system during measurements for the timely detection of deviations in the gas exchange system were used.
