What is a typical result of high levels of Carbon Dioxide (CO2) in an enclosed space?

High levels of Carbon Dioxide (CO2) in an enclosed space can lead to dangerous physiological effects, including nervous system shutdown. When CO2 concentrations rise, it can displace oxygen in the air, leading to insufficient oxygen supply for the body. The central nervous system is particularly sensitive to changes in oxygen levels, and excessive CO2 can result in dizziness, confusion, and ultimately unconsciousness if exposure is prolonged. This condition is often referred to as hypercapnia, which can manifest symptoms ranging from a mild headache to severe impairments in cognitive and physical functions, including loss of consciousness or shutdown of the nervous system. Understanding the impact of high CO2 levels is critical in ensuring adequate ventilation and maintaining a safe environment in enclosed spaces.
