Task Book: Entry
Principal Investigator: Ryder, Valerie

Short Title: Acute CO2 Exposure with Existing Measures

Responsible HRP Element: Human Factors and Behavioral Performance

Collaborating Org(s):

Funding Status: Completed - Task completed and produced a deliverable

Procurement Mechanism(s):

Solicited

Aims:

The purpose of this task is to investigate the effects of the elevate CO2 environment in a controlled analog setting with existing available measures to understand potential behavioral and performance effects that may result. This will help to characterize the risk of the elevated CO2 environment on cognition and sleep.

Aim1: Determine if and to what degree the impaired cognitive function and performance impacts seen in previous studies with acute exposure to CO2 can be replicated in an astronaut-like population.

Aim 2: Determine, by use of the Cognition battery of psychometric measures, if CO2, at or below operationally relevant concentrations, affects cognitive functions of astronaut-like subjects.

This task also informs the Sensorimotor discipline area: SM 2.1

Mappings

Risk of Adverse Cognitive or Behavioral Conditions and Psychiatric Disorders

CBS-BMed3: We need to identify and quantify the key threats to and promoters of mission relevant behavioral health and performance during autonomous, long duration and/or long distance exploration missions.

Effects of Acute Exposures to Carbon Dioxide upon Cognitive Functions

Risk of Performance Decrements and Adverse Health Outcomes Resulting from Sleep Loss, Circadian Desynchronization, and Work Overload

Sleep Gap 10: We need to identify the spaceflight environmental and mission factors that contribute to sleep decrements and circadian misalignment, and their acceptable levels of risk.
