The Bends/DCS in very simple terms
You do not need to understand much science to understand DCS how to avoid getting it. 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. How deep can you dive without decompression chamber?
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.

Can you get the bends from diving 20 feet?
I asked the instructor and he said at 20 feet no one gets DCS/DCI/Bends, and not to worry. They do certification at max 30 feet so they don't have to worry about Bends.
Why do freedivers 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 Is The DEEPEST A Human Can DIVE? Myths Debunked (Animation)
At what depth do you risk the 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. The deeper you dive, the greater the effect.
How far down can you go in the ocean before being crushed?
Human bone crushes at about 11159 kg per square inch. This means we'd have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.
What is the deepest free dive?
Deepest no-limits freedive
The record for deepest no-limit freediving is 214m (702ft), held by Austrian world champion Herbert Nitsch, who set the record on 14 June 2007 in Spetses, Greece.
How long can you scuba dive at 60 feet?
What is the No Decompression Limit for 60 feet? The NDL or No-Stop time for 60 feet / 18 meters is 56 minutes according to the Recreational Dive Planner table. On a Suunto dive computer using their algorithm, the NDL is 51 minutes for your first dive.
Can you fart while diving?
Farting is possible while scuba diving but not advisable because: Diving wetsuits are very expensive and the explosive force of an underwater fart will rip a hole in your wetsuit. An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness.
How deep do Navy divers go?
COMCAM detachments are assigned to the Naval Expeditionary Combat Command among other commands. by the diving equipment used. Recompression System. pressure to a depth of 2300 feet.
At what depth do you start sinking?
Most humans hit negative buoyancy around 30 feet down.
Can you scuba dive every day?
A lot of us might wonder, how often can you actually go scuba diving? Yes, you can scuba dive every day. As long as you remain with the dive table safety limits or use a dive computer. You have to monitor all your prior dives depth and bottom time, but 18-24 hours is plenty of time to recover between dives.
How deep can you dive without Nitrox?
If nitrogen causes narcosis and you're breathing less of it, you should have less narcosis. The trouble is, the depth range where you start worrying about narcosis (100 to 130 feet) is also where you have to stop using nitrox because of the risk of oxygen toxicity.
How long can one scuba tank last?
But how long a scuba tank lasts also directly depends on the depth at which it's used. Based on personal experience, an average open water certified diver using a standard aluminum 80-cubic-foot tank on a 40-foot dive will be able to stay down for about 45 minutes before surfacing with a safe reserve of air.
Do your lungs shrink when you dive?
As external pressure on the lungs is increased in a breath-holding dive (in which the diver's only source of air is that held in his lungs), the air inside the lungs is compressed, and the size of the lungs decreases.
How deep has a human gone in the ocean?
Vescovo's trip to the Challenger Deep, at the southern end of the Pacific Ocean's Mariana Trench, back in May, was said to be the deepest manned sea dive ever recorded, at 10,927 meters (35,853 feet).
How deep can a divemaster dive?

What's the deepest dive by a human?
Explorer and businessman Victor Vescovo descended 35,853 feet (10,927 meters) into the Pacific Ocean, breaking the record for deepest dive ever. At the very bottom, he found colorful rocky structures, weird critters and the ever-pervasive mark of humankind — plastic.
How deep do oil rig divers go?
Offshore, inland and coastal commercial divers now work in conventional surface air supplied helmet gear to depths of 180 to 200 feet. Scuba diving is permitted by OSHA regulations to those depths under limited conditions. From 200 to 300 feet, diving rigs using helium and oxygen as a breathing medium are used.
How much underwater pressure can a human withstand?
Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides.
Can you get the bends in shallow water?
"It is now clear that even shallow water dives can produce decompression sickness," said Dr Griffiths, director of the Hyperbaric Medical Unit at Townsville Hospital. "This condition is quite difficult to diagnose and, untreated, can lead to permanent disability."
How do whales not get the bends?
"The only stressor known to cause this kind of bone damage is the bends," he says. This implies that the whales stave off the effects of the bends not through some in-built physiological mechanism, but rather by carefully managing their diving patterns much as scuba-divers do.
Can you drink alcohol the night before scuba diving?
Avoid drinking to excess anytime, but particularly before diving or while on a diving vacation. Avoid alcohol for at least 8 hours before diving (the same rule the FAA imposes on pilots). If you drank the night before, avoid diving if you feel a hangover, as you're likely to be significantly dehydrated.
