According to NAUI, what is the maximum recommended ascent rate?

The maximum recommended ascent rate according to NAUI is typically set at 30 feet per minute. This ascent rate is designed to help mitigate the risk of decompression sickness as it allows for adequate time for the body to off-gas nitrogen that has been absorbed during the dive. Ascending too quickly can increase the likelihood of bubbles forming in the bloodstream and tissues, which can lead to serious health issues.

Maintaining this ascent rate provides the diver with a manageable pace, allowing for the possibility of safety stops, particularly at critical depths like 15 to 20 feet, which further contributes to safe diving practices. It's important for divers to prioritize safety and adhere to recommended ascent rates to promote a safe return to the surface after diving activities.
