How long after diving can you get decompression sickness?
Symptoms of DCS can occur immediately after surfacing or up to 24 hours later. On average a diver with DCS will experience symptoms between 15 minutes and 12 hours following a dive.
At what point do you get the bends?
They almost always develop within 48 hours of the dive (or another event) taking place. However, it is more common for them to develop within 6 hours or even within the first hour. Some of the most common symptoms of the bends include: Joint pain – especially around major joints like the shoulders and elbows.
What does a mild case of the bends feel like?
The most common signs and symptoms of the bends include joint pains, fatigue, low back pain, paralysis or numbness of the legs, and weakness or numbness in the arms. Other associated signs and symptoms can include dizziness, confusion, vomiting, ringing in the ears, head or neck pain, and loss of consciousness.
Will the bends go away on its own?
In some cases, symptoms may remain mild or even go away by themselves. Often, however, they strengthen in severity until you must seek medical attention, and they may have longer-term repercussions.
Can the bends be cured?
If DCS is suspected, it is treated by hyperbaric oxygen therapy in a recompression chamber. Diagnosis is confirmed by a positive response to the treatment. If treated early, there is a significantly higher chance of successful recovery.
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.
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.
What happens when a diver gets the bends?
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.
Why is it called the bends in diving?
Decompression sickness (DCS), known as ‘the bends’ because of the associated joint pain, is a potentially deadly condition caused by bubbles of nitrogen gas forming in the blood and tissues. It’s most common among divers using scuba tanks, but can affect free-divers and people at high altitude.
