In extreme cases, it

Can you survive 47 meters underwater?
Regardless of how well you can extend your breath (and remember, you must never ever hold your breath),
a scuba tank at 47 meters will not last very long
. This is excluding the amount of time and the air you will use to descend and of course, slowly ascend.
How deep under water can a human go?
The maximum depth reached by anyone in a single breath is
702 feet (213.9 metres)
and this record was set in 2007 by Herbert Nitsch. He also holds the record for the deepest dive without oxygen – reaching a depth of 831 feet (253.2 metres) but he sustained a brain injury as he was ascending.
Can you die from decompression sickness?
The more severe type of decompression sickness most commonly results in neurologic symptoms, which range from mild numbness to paralysis and
death
. The spinal cord is especially vulnerable. Symptoms of spinal cord involvement can include numbness, tingling, weakness, or a combination in the arms, legs, or both.
Can you die from underwater pressure?
Pressure changes can cause injuries when you drop down into the water (descend) and come back up (ascend). Scuba injuries may be mild. But in some cases,
they can cause serious problems or even death
.
Can you fart while diving?
Farting is possible while scuba diving
but not advisable because: … An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness. The acoustic wave of the underwater fart explosion can disorient your fellow divers.
Why can’t humans go deep underwater?
At only a few feet below the surface,
the water pressure
is already too great for the muscles that expand and contract our lungs to work, making it extremely difficult for us to draw breath.
What is the largest shark alive?
The biggest known predatory species, the great white shark (Carcharodon carcharias), grows to only about 20 feet (6 m) long, and the filter-
feeding whale shark (Rhincodon typus)
, the biggest fish species alive today, measures about 18 to 33 feet (6 to 10 m) from nose to tail tip, on average.
How long is air good in a scuba tank?
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 to 60 minutes
before surfacing with a safe reserve of air still in the tank.
Did they use real sharks in 47 meters down?
Unfortunately, the
caves
are also the home of great white sharks that have evolved from their time living in them for what could be centuries. Hopefully, you’re already aware this premise is completely fabricated, and that anyone going on an underwater cave jaunt will not encounter mutated great white sharks …
Is dying from the bends painful?
Signs and symptoms of
decompression sickness
Sometimes a dull ache, more rarely a sharp pain. Active and passive motion of the joint may aggravate the pain. The pain may be reduced by bending the joint to find a more comfortable position. If caused by altitude, pain can occur immediately or up to many hours later.
What do 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.
What body systems are affected underwater?
Immersion of the human body in water has effects on the
circulation, renal system and fluid balance
, and breathing, which are caused by the external hydrostatic pressure of the water providing support against the internal hydrostatic pressure of the blood.
How are deep sea fish not crushed?
Under pressure
Fish living closer to the surface of the ocean may have a swim bladder – that’s a large organ with air in it, which helps them float up or sink down in the water. Deep sea fish don’t have these
air sacs
in their bodies, which means they don’t get crushed.
What is at the bottom of the ocean?
The seabed
(also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as ‘seabeds’.
