Effects of acute exposures to carbon dioxide on decision making and cognition in astronaut-like subjects.

ABSTRACT: Acute exposure to carbon dioxide (CO₂) concentrations below those found on the International Space Station are reported to deteriorate complex decision-making. Effective decision-making is critical to human spaceflight, especially during an emergency response. Therefore, effects of acutely elevated CO₂ on decision-making competency and various cognitive domains were assessed in astronaut-like subjects by the Strategic Management Simulation (SMS) and Cognition test batteries. The double-blind cross-over study included 22 participants at the Johnson Space Center randomly assigned to one of four groups. Each group was exposed to a different sequence of four concentrations of CO₂ (600, 1200, 2500, 5000 ppm). Subjects performed Cognition bef
