How can a diver determine their no-decompression limits when using Nitrox?

Determining no-decompression limits (NDLs) when using Nitrox is essential for ensuring a safe diving experience. The correct approach is to consult dive tables or dive computer settings that are specific to the Nitrox mixture you are using.

Dive tables or dive computers are designed to provide precise data about the no-decompression limits based on the specific mix of oxygen and nitrogen in your Nitrox blend. Each mix affects gas absorption and off-gassing times differently, and these resources incorporate the physiological factors needed to avoid decompression sickness. Using dive tables or a dive computer tailored to your specific Nitrox mixture accurately accounts for your depth and time, offering a reliable way to maintain safety underwater.

Estimates based on previous dives without the appropriate reference can lead to unsafe practices since each dive and mixture can result in different physiological impacts. Similarly, relying solely on experience or the recommendations of fellow divers without the support of accurate data could result in miscalculations, increasing the risk of decompression sickness. Therefore, utilizing the structured data from dive tables or a dive computer is the most reliable method for determining no-decompression limits when diving with Nitrox.
