Bubbles forming in or near joints are the presumed cause of joint pain (the bends). With high levels of bubbles, complex reactions can take place in the body. The spinal cord and brain are usually affected, causing numbness, paralysis, impaired coordination and disorders of higher cerebral function.
How painful are the bends?
Symptoms of the bends include: Joint pain: Gas bubbles can get stuck in joints and stretch ligaments and tendons in ways they shouldn’t. The result is a deep and throbbing pain that you feel inside your joint. The elbow and shoulder are the most common spots, but you can also get the bends in your knees and hips.
How deep do you have to dive for the bends?
At what depth do the bends occur? Most often, the bends are a real concern after 30 feet (9.1 m). The deeper you go, the more likely you are to run into the bends if you surface too quickly. Once you dive deeper than 30 feet (9.1 m), the bends become a serious potential problem.
How serious are the bends?
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.
What happens if you get the bends? – Related Questions
Can you reverse bends?
The Bends Prognosis
Prognosis is good with hyperbaric oxygen treatment. Delay to hyperbaric oxygen treatment: Although reports show that divers can do well after days of symptoms, delay in definitive treatment may cause damage that is irreversible.
How quickly do you get the bends?
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.
How long do you have to treat the bends?
1) Professional treatment for the Bends
A hyperbaric re-compression chamber is the device required for treatment of DCS: Hyperbaric treatment can take as long as 12 hours or more depending on the severity of symptoms.
What does the bends feel like?
fatigue, low back pain, paralysis or numbness of the legs, and. weakness or numbness in the arms.
How likely is it to get the bends?
Joint pain (“the bends”) accounts for about 60% to 70% of all altitude DCS cases, with the shoulder being the most common site for altitude and bounce diving, and the knees and hip joints for saturation and compressed air work.

How far down is bends?
The Bends/DCS in very simple terms
Anyone who dives deeper than 10 metres (30ft.) while breathing air from a scuba tank is affecting the balance of gases inside the tissues of their body.
What are the 4 types of bends?
Most tubes, though, are bent one of four ways: ram-type bending, roll bending, compression bending, or rotary draw bending. Pipe is specified by its nominal pipe size, while tube is specified by its outside diameter.
How do free divers not get the bends?
Decompression sickness (DCS) after freediving is very rare. Freedivers simply do not on-gas enough nitrogen to provoke DCS. Thus, very few cases of DCS in freedivers have ever been reported, and these have involved repeated deep dives in a short time frame.
What bends does not break?
“Bamboo is flexible, bending with the wind but never breaking, capable of adapting to any circumstance. It suggests resilience, meaning that we have the ability to bounce back even from the most difficult times. . . .
What are the three types of bends?
If you’re a newbie to metal fabrication, here’s a refresher on the essentials of bending. Air bending, bottom bending and coining are the three main types employed by precision metal fabricators.
Should you break on a bend?
You should always avoid braking on a bend, but there will be occasions when there is no option. A pedestrian may step out into your path or you may overestimate the safe speed. When it is necessary to brake, apply pressure as lightly as possible to the pedal to avoid asking too much from the tyres.
How many types of bends are there?
There are three types of bends used to form metal that any sheet metal engineer or press brake operator must be familiar with; Air Bending, Bottom Bending and Coining.
How do you test for bends?
Bending tests are conducted by placing a length of material across a span and pushing down along the span to bend the material until failure. Bending tests reveal the elastic modulus of bending, flexural stress, and flexural strain of a material.
Why do bends cause head loss?
Loss of head due to bend in pipe: This is the energy loss due to bend. When a bend is provided in the pipeline, there is a change in direction of the velocity of flow (figures 3 and 4). Due to this, the flow separates from the walls of the bend and formation of eddies takes place.
How do you do bends properly?
How to Bend Correctly
- Don’t stand with your feet together.
- Bend at the hips and knees, not at the waist.
- Pull in your belly (abdominal) muscles and tighten your thigh muscles.
- Keep your spine straight.
- Place a hand on a wall or fixed heavy object, such as a desk for support, if needed.
What are the basic bends?
There are three basic bends that are commonly used: the 90° bend, the common offset, and the saddle. A more advanced type of bend called a concentric bend is discussed in a separate article.
