What is the decompression obligation after a dive to 110' for 25 minutes?

After a dive to a depth of 110 feet for 25 minutes, the appropriate decompression obligation involves spending time at a shallower depth to safely off-gas the nitrogen that has accumulated in the body during the dive. The correct answer indicates that a diver should spend 5 minutes at a depth of 15 feet. This specific decompression stop allows for a controlled ascent to help prevent decompression sickness, also known as "the bends."

Decompression stops are based on dive tables or dive computers that indicate how long a diver can stay at certain depths without requiring extended surface intervals to prevent nitrogen buildup in the tissues. The decision to include a decompression stop at a specific depth is essential to manage the body’s absorption and release of nitrogen effectively. At 15 feet, the surrounding pressure is lower, which aids in quicker off-gassing.

This knowledge is vital for divers to ensure safety and minimize the risk of injury from improper ascent or rapid changes in pressure. By following this required decompression obligation, divers can safely complete their diving activities without significant risk to their health.
