Key result
High oxygen concentration maintained vehicle velocity more consistently and increased oxyhaemoglobin concentration in the prefrontal and parietal cortices during simulated driving.
Why the study?
While high oxygen concentration improves cognitive ability for single tasks, few studies have investigated its effect on complex cognitive tasks such as driving.
Does high oxygen concentration improve driving performance and cerebral hemodynamic response in volunteer subjects?
Does high oxygen concentration improve driving performance and cerebral hemodynamic response in volunteer subjects?
High oxygen concentration may improve complex cognitive task performance such as driving consistency and increase cerebral activation in the prefrontal and parietal cortices.

High oxygen may aid driving consistency; hypothesis-generating and should not change practice without randomized confirmation.
The positive effect of a high oxygen concentration on human cognitive ability for single tasks has been proven in various ways; however, few studies have investigated its effect on complex cognitive tasks. The aim of this study was to investigate the effect of a high oxygen concentration in driving situations that require complex cognitive abilities. The experiment was conducted in a laboratory equipped with a car simulator with 10 volunteer subjects. Driving was performed under normal and high-oxygen-concentration conditions. Various driving parameters and oxyhaemoglobin (HbO) levels in certain brain areas were measured during the experiments. The results show that vehicle velocity was maintained more consistently in the high-oxygen-concentration condition, and the HbO concentration increased (indicating greater activation) in the prefrontal and parietal cortices.

Kim et al. (2025) studied this question. High oxygen concentration vs. Normal oxygen concentration was evaluated on Driving parameters (vehicle velocity consistency) and oxyhaemoglobin (HbO) levels. High oxygen concentration maintained vehicle velocity more consistently and increased oxyhaemoglobin concentration in the prefrontal and parietal cortices during simulated driving.
