Determining how different levels of indoor carbon dioxide affect human monotonous task performance and their effects on human activation states using a lab experiment: a tracking task.
Different individuals respond differently to carbon dioxide (CO2) levels in the local atmosphere. We aimed to determine whether brain activity changes with various CO2 concentrations and whether this is correlated with heart rate and arterial oxygen saturation (SPO2). We used electrocardiograms, SPO...

We aimed to determine whether brain activity changes with various CO2 concentrations and whether this is correlated with heart rate and arterial oxygen saturation (SPO2). We used electrocardiograms, SPO2 measurements, electroencephalograms, and task performance metrics in various CO2 concentrations and studied the changes in these metrics. We found that SPO2 did not change in various CO2 conditions; elevations in CO2 up to 4000 ppm had no measurable influence on ventilation and SPO2, suggesting no effect on monotonous task performance seen in terms of the alpha wave band rate. However, heart rate increased as early as within 15 min. We found that some individuals who naturally have lower SPO2 values tended to undergo faster lowering of arousal level. Practitioner summary: SPO2 may be an individual characteristic that affects the human ability to maintain concentration in monotonous tasks in enclosed spaces, such as driving a car. This study highlights the fact that different individuals respond differently to various CO2 levels, based on SPO2 levels, as manifested by decreased concentration and brain activity.
