At what depth do divers need to decompress?
The need to do decompression stops increases with depth. A diver at 6 metres (20 ft) may be able to dive for many hours without needing to do decompression stops. At depths greater than 40 metres (130 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed.
Why is it important for divers to know the exact depth of their dive?
The deeper a diver goes, the less time they have before their tissues absorb the maximum allowable amount of nitrogen. Because pressure becomes greater with depth, both air consumption rates and nitrogen absorption increase the deeper a diver goes.
What happens if you don’t equalize underwater?
However, if a diver does not equalize early or often enough, the pressure differential can force the soft tissues together, closing the ends of the tubes. Forcing air against these soft tissues just locks them shut. No air gets to the middle ears, which do not equalize, so barotrauma results.
How deep can you dive without worrying about the bends?
There’s a bit of physics and physiology involved in a full explanation, but the short answer is: 40 metres/130 feet is the deepest you can dive without having to perform decompression stops on your way back to the surface.
When Should divers equalize?
A diver needs to equalize approximately every two to three feet (1 m). Doing so is particularly important in the first 15 to 30 feet (5 to 10 m) of the dive. This is when the largest proportional pressure change takes place.
Do you need to equalize when scuba diving?
Let’s review some basic dive physiology. Failing to do this causes ears to hurt when diving, and potentially damages the delicate mechanisms of the ear. But you knew this already. The key to safe equalizing is to get air to flow from the throat to the ears through the opening of the normally closed eustachian tubes.
What is the deepest you can dive?
With recreational diving, the answer to the question “how deep can you SCUBA dive?” is 130 feet. Proper certification is highly recommended for those depths of SCUBA diving. As a basic open water SCUBA diver, the limit for how deep can you dive is 60 feet.
