Breath analysis using a spirometer and volatile organic compound sensor on driving simulator
In this study the correlation between the condition of drivers and their expiration was evaluated by
analyzing the exhalation of car drivers in a simulation setting using a spirometer and a volatile
organic compound (VOC) gas sensor. Participants wore exhalation masks and their expiration was
monitored for fluctuations in breath measurements, including VOC concentration, oxygen intake,
carbon dioxide excretion, and respiration rate. Participants used a driving simulator on four
different courses of varying difficulty for approximately five min each, with the mean and standard
deviation (SD) being calculated for each parameter during the cruising section of the course. After
driving each course, participants assessed the ‘enjoyment’ and ‘difficulty’ of their experience. It
was verified whether the state of the participants during driving can be determined from exhalation
by comparing the questionnaire results. The mean and SD of all exhalation parameters were analyzed
using box-a...
