Scuba Diving: Carbon Dioxide Toxicity
Carbon Dioxide Toxicity Overview
Inadequate ventilation when scuba diving results in carbon dioxide build-up. Inadequate breathing, a tight wetsuit, overexertion, regulator malfunction, deep diving, and contamination of the air supply with exhaled gases often cause a carbon dioxide buildup. Carbon dioxide levels in the blood can increase, causing shortness of breath and sedation, resulting in carbon dioxide toxicity.
