What happens if you descend too fast while diving?

Does it matter how fast you descend scuba diving?

There are many reasons for learning to descend properly. 1- Descending fast can to lead to the risk of squeezing out air spaces in our ears. We need to descend slower to allow air spaces, such as in our ears and mask, enough time to equalize as the pressure changes.

How fast can you descend in water?

The answer varies among scuba certification organizations. Some organizations list a maximum ascent rate of 30 feet/9 meters per minute, while others allow a faster ascent rate. For example, old PADI dive tables (based on the US Navy Dive Tables) allow a maximum ascent rate of 60 feet/18 meters per minute.

How fast can you descend?

It depends on the altitude the plane was flying at when the depressurization occurred. Airliners can descend over 8,000 feet per minutes if needed. A descent from 35,000 feet at that rate would have you down to 11,000 feet in 3 minutes or less.

What happens if you descend too quickly?

Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues. This doesn’t cause a problem when a diver is down in the water.

How deep can you free dive without decompression?

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.

How do you ascend slowly when diving?


When you are ready to ascend, hold your inflator hose in your left hand and have your finger on the deflate button. You should start to kick up slowly, while continuously releasing air from your BCD. This stops the air in your BCD from expanding too much and pulling you up too quickly!
