What happens when divers go too deep?

Why is it dangerous to dive deep?

Like nitrogen, the body absorbs extra oxygen under increased underwater pressure as well. For most divers this is not a problem, but at extreme depths so much extra oxygen is absorbed that this life-giving gas becomes toxic. The effects include tunnel vision, nausea, twitching, loss of consciousness and seizures.

What happens if you dive too long?

In other cases, a diver can slip into a coma while still deep underwater. Trying to get yourself back to the surface can also lead to complications. If you rise too quickly, you could develop decompression sickness, often called the bends.

At what depth does diving become dangerous?

With recreational diving, the answer to the question “how deep can you SCUBA dive?” is 130 feet. Proper certification is highly recommended for those depths of SCUBA diving. As a basic open water SCUBA diver, the limit for how deep can you dive is 60 feet.

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.

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.

Is scuba diving hard on your body?

Scuba diving exposes you to many effects, including immersion, cold, hyperbaric gases, elevated breathing pressure, exercise and stress, as well as a postdive risk of gas bubbles circulating in your blood. Your heart’s capacity to support an elevated blood output decreases with age and with disease.

What problems can occur if a diver comes up too quickly after being more than 10 m underwater?

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 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.
