Carbon Dioxide Scrubbers

[This is an article in progress, and is currently being written]

A steady supply of oxygen alone is insufficient to keep astronauts breathing. While the intake of oxygen is essential for respiration, the by-product of this respiration is the exhalation of approximately one kilogram of carbon-dioxide per day.^[1] The concentration of this gas in Earth's atmosphere is roughly 0.04%, but in the close confines endured by astronauts, accumulations of CO₂ can quickly reach toxic levels.^[2]

Symptoms Experienced According to CO₂ Level^[2]
CO₂ Concentration	Symptoms
1%	Drowsiness
3%	Impaired hearing, increased heart rate and blood pressure, stupor
5%	Shortness of breath, headache, dizziness, confusion
8%	Unconsciousness, muscle tremors, sweating
>8%	Death
