What is the recommended ascent rate for divers to minimize decompression sickness risk?

The recommended ascent rate for divers to minimize the risk of decompression sickness is 30 feet per minute. This rate is considered a safe ascent speed as it allows sufficient time for nitrogen, absorbed during the dive at deeper pressures, to be eliminated from the body in a controlled manner.

Ascending too quickly can increase the likelihood of nitrogen bubbles forming in the bloodstream or tissues, which is the primary cause of decompression sickness. By adhering to the 30 feet per minute guideline, divers can avoid overwhelming their body’s ability to safely release this gas, thereby reducing the risk of injury.

Moreover, it is also essential to incorporate safety stops during ascent, especially after deeper or longer dives, to further decrease the risk of decompression sickness.
