What does HYPERBARIC mean in the context of diving?

In the context of diving, the term "hyperbaric" specifically refers to environments where the pressure is greater than the normal atmospheric pressure at sea level, which is approximately 1 atmosphere (atm). This is particularly relevant in diving situations, especially when divers are underwater, as the pressure increases with depth. The principles of hyperbaric physics are crucial for understanding how gases behave at increased pressures, which informs safety protocols such as decompression procedures.

For example, hyperbaric chambers are used in medical treatments for decompression sickness and other conditions related to increased pressure. In diving, being in a hyperbaric environment necessitates special considerations, such as the management of nitrogen absorption in the body and the potential risks associated with rapid ascents. Understanding hyperbaric conditions helps divers and supervisors ensure safe diving practices and minimize the risk of pressure-related injuries.
