Effects of Acute Exposures to Carbon Dioxide upon Cognitive Function (Acute_CO2_Exposure)

Behavior and performance

Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
A previous study demonstrated that carbon dioxide (CO2) at concentrations below 2 mm Hg significantly impacts some cognitive functions that are associated with the ability to make complex decisions in conditions that are characterized by volatility, uncertainty, complexity, ambiguity, and delayed feedback. All of these conditions may be encountered by space flight crews in off-nominal situations, or during the first missions beyond low Earth orbit. The objective of this study was to extend the original study by using measures of cognitive domains to determine if astronaut-like subjects are sensitive to concentrations of CO2 at, or below, limits currently controlled by flight rules.

Human Research Program (HRP) Human Research Roadmap (HRR) Information
Crew health and performance is critical to successful human exploration beyond low Earth orbit. The Human Research Program (HRP) investigates and mitigates the highest risks to human health and performance, providing essential countermeasures and technologies for human space exploration. Risks include physiological and performance effects from hazards such as radiation, altered gravity, and hostile environments, as well as unique challenges in medical support, human factors, and behavioral health support. The HRP utilizes an Integrated Research Plan (IRP) to identify the approach and research activities planned to address these risks, which are assigned to specific Elements within the program. The Human Research Roadmap is the web-based tool for communicating the IRP content.
