Managing Exposure to Nitrogen

Key Points

• The key to reducing the risk of decompression sickness is knowing and remaining within the No-Decompression Limits (NDLs).

• A No-Decompression Limit is the maximum time a diver can stay at a particular depth and still ascend without the need to make mandatory decompression stops.

• Decompression diving requires special training and equipment; this is why recreational divers need to remain within the no-stop limits.
