hypercapnia
Quick Summary
Hypercapnia is a medical condition characterized by an excessive amount of carbon dioxide in the blood. This can occur in various situations, including during diving when impaired alveolar ventilation at depth leads to carbon dioxide retention.12
The body regulates carbon dioxide levels through a complex system involving carbonic acid, which is formed when carbon dioxide dissolves in water. This process is crucial for transporting carbon dioxide in the blood. When carbon dioxide levels become too high, it can lead to hypercapnia.312
