Hostile, enclosed spaceflight environments (including space vehicles and suits) do not have the benefit of natural carbon dioxide (CO2) removal. In these environments, equipment (e.g., the Carbon Dioxide Removal Assembly, lithium hydroxide, and amine systems) control CO2 levels and mitigate consequences of elevated CO2 exposure.
