What does the process of decompression involve after a deep dive?

The process of decompression after a deep dive is vital for safety and involves gradually ascending through designated depths. This method allows dissolved gases, particularly nitrogen, which accumulates in the body under high pressure, to be released safely. A rapid ascent can lead to decompression sickness, also known as "the bends," which occurs when gas bubbles form in the body due to a sudden decrease in pressure.

By ascending slowly and stopping at specific depths for pre-determined periods, divers can facilitate the safe elimination of these gases from their systems, minimizing the risks associated with pressure changes. Proper decompression protocols are established by diving physiology, and they are critical to ensuring that divers emerge from high-pressure environments without adverse health effects.

In contrast, immediate ascent to the surface or simply waiting at the surface is not recommended, as these methods can lead to serious complications. Additionally, while hyperbaric chambers can play a role in treating decompression sickness, they are not part of the immediate decompression process which must be followed by divers after a deep dive.
