decompressiestop

Decompressiestop is a term used in scuba diving that refers to a mandatory pause or pauses made at specific depths during a descent or ascent to allow the body to off-gas inert gases absorbed from breathing compressed air. These stops are crucial for preventing decompression sickness, commonly known as "the bends," which occurs when dissolved gases form bubbles in the body tissues as ambient pressure decreases too rapidly.

During ascent from a dive, divers are required to make decompression stops at predetermined depths for specific durations. The depth and time of these stops are calculated based on the depth and duration of the dive using dive tables or dive computers. These calculations are based on physiological models that predict how inert gases like nitrogen are absorbed and eliminated by the body.

There are two main types of decompression stops: mandatory stops and safety stops. A safety stop is a precautionary stop, typically at 5 meters (15 feet) for 3-5 minutes, which is recommended on almost all dives, even those that do not require mandatory decompression stops. Mandatory decompression stops are required for dives that exceed the no-decompression limit (NDL), meaning the diver has spent too much time at depth for a safe ascent without pauses. Failing to perform required decompression stops can lead to serious health consequences. Divers must be properly trained and follow their dive plan meticulously to ensure safe ascents.
