Using the NOAA air table, what is the maximum no stop dive time for a dive to 55'/16.8m?

The correct answer indicates that for a dive to a depth of 55 feet (or approximately 16.8 meters), based on the NOAA air table, the maximum no-stop dive time is 74 minutes. This means that a diver can remain at this depth for up to 74 minutes without exceeding the safe limits for nitrogen absorption, thereby avoiding the risk of decompression sickness during ascent.

The NOAA air tables are designed to provide divers with essential information regarding safe dive durations at various depths while breathing air. They take into account factors such as pressures and nitrogen saturation levels in the body. At a depth of 55 feet, the relationship between depth and allowable time has been defined through extensive research and diving experience.

In practice, staying within these recommended limits is critical to ensure safety during dives, particularly when multiple dives are being planned over a short period. Comprehension of these tables and time limits is fundamental for divers to manage their exposure to nitrogen and plan their dives accordingly.
