Study of exhaled air composition during recovery after respiratory disease by mass spectrometric analysis

This article considers the possibility of monitoring recovery after respiratory diseases by mass spectrometric methods. Two groups of test subjects took part in the study: 18 individuals who had had a respiratory viral infection and 31 healthy volunteers in good physical condition. A noninvasive mass spectrometric method of controlling the gas composition of exhaled air was used in the study. The results of the experiment demonstrate the effectiveness of the technique: the differences detected in the mass spectra of healthy people and subjects who had a respiratory viral infection allow the technique to be used to search for pathology markers.
