What is a key reason to perform decompression in a recompression chamber rather than underwater?

Performing decompression in a recompression chamber rather than underwater is primarily favored because it is less time-consuming and safer. In the controlled environment of a recompression chamber, various factors can be precisely managed, such as atmosphere composition, temperature, and pressure, which are critical for effective decompression.

Decompression underwater can be risky due to environmental hazards, varying water pressures, and potential complications that can arise during the process, such as equipment failure or the diver’s physical distress. In a recompression chamber, divers are monitored closely by trained personnel, which allows for immediate response to any distress signals and a more systematic approach to managing decompression schedules.

In addition, safety protocols can be easily implemented in a controlled environment, reducing the risks associated with underwater decompression, including the dangers of nitrogen bubbles forming in the bloodstream. The chamber provides a clearer, more stable environment for monitoring and controlling the decompression process, which ultimately contributes to a safer outcome for the diver.
