What is the role of oxygen exposure monitoring in diving?

The role of oxygen exposure monitoring in diving is primarily aimed at minimizing the risks of oxygen toxicity. When divers breathe gas mixtures containing oxygen, particularly at elevated pressures, there is potential for oxygen toxicity to occur. This condition can lead to various harmful effects on the central nervous system and lungs, including seizures and other serious health complications.

Monitoring oxygen exposure allows divers to track their oxygen levels and ensure they remain within safe limits. These limits are defined based on partial pressure, which increases with depth. By carefully managing the time spent at particular depths and using appropriate gas mixtures, divers can avoid exceeding safe oxygen thresholds, thereby reducing the risk of toxicity.

In the context of diving, understanding and adhering to oxygen exposure limits is essential for maintaining diver safety and health during underwater activities. The other options, while related to various aspects of diving, do not directly pertain to the specific concerns surrounding oxygen levels and toxicity management.
