Question: Why shouldn’t divers move up to the surface of the water after a deep dive?

Why shouldn’t divers move up to the surface of the water after a deep dive?

“The bends” are even scarier. As you come to the surface from a dive, nitrogen gas can bubble up in your body like carbonation in a freshly opened can of soda. If you swim up too fast, decreasing pressure makes the bubbles expand, which can cause severe pain in your joints and create other problems in your body.

Why is it dangerous for a deep sea diver to come up to the surface very fast?

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.

What would happen to a diver if they were to go too deep into the water?

A: It’s a form of decompression sickness initially observed in deep sea divers. At great depths under water the excess pressure causes nitrogen gas to be absorbed into the blood. If the diver surfaces too quickly the nitrogen forms bubbles in the blood which raise havoc in the body.

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 divers go straight up?

Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. … But if a diver rises too quickly, the nitrogen forms bubbles in the body. This can cause tissue and nerve damage.

What is the most serious and dangerous diving emergency?

CNS toxicity is the more dangerous form of oxygen toxicity due to the risk of having convulsions under water. The second type is pulmonary toxicity, which can affect the lungs or other parts of the body. Symptoms include chest pain and discomfort, coughing and fluid in the lungs.

What happens if you don’t equalize when diving?

However, if a diver does not equalize early or often enough, the pressure differential can force the soft tissues together, closing the ends of the tubes. Forcing air against these soft tissues just locks them shut. No air gets to the middle ears, which do not equalize, so barotrauma results.

What is the most common injury in scuba diving?

The most common injury in divers is ear barotrauma (Box 3-03). On descent, failure to equalize pressure changes within the middle ear space creates a pressure gradient across the eardrum.

What does 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.
