What is Carbon Dioxide?

Considering the health effects of carbon dioxide on human health, this element is commonly measured and monitored inside of buildings to safeguard the health and safety of occupants.

Carbon Dioxide (CO2is a naturally occurring greenhouse gas that is commonly produced by the air we exhale. Carbon dioxide is harmless in small amounts, but high levels can negatively impact productivity. Indoor carbon dioxide concentrations are created through a combination of outdoor carbon dioxide, breathing, and poor ventilation. To save energy, many modern ventilation systems use recycled air instead of cycling in new air.  

Typically, higher CO2 levels mean that there is less fresh air coming into your facility. By examining CO2 levels in your building, you can determine if your HVAC systems are operating effectively and within guidelines. Levels of CO2 are measures in percent or parts per million. High levels of CO2 often indicate that there is a problem with air circulation.

Carbon Dioxide Health Effects

Carbon dioxide health effects can cause different reactions in different people. Exposure to CO2 can cause headaches, restlessness, dizziness, difficult breathing, tingling, tiredness, sweating, increased heart rate and elevated blood pressure. In some cases, it can even lead to convulsions, asphyxia, or comas.

High CO2 levels can also adversely affect cognitive abilities, which includes the inability to perform tasks and make decisions.  

Typical CO2 levels for indoor spaces with proper air exchange should range between 400 and 1,000ppm.  Any measurements over 1,000 ppm are typically associated with drowsiness and complaints of poor air. Levels over 2,000 ppm can lead to stale air, poor concentration, and loss of attention. 5,000 ppm signifies unusual air quality conditions where toxicity or oxygen depravation can occur.
