Question: Why does diver survive the pressure?

What happens to your body if you dive too deep?

In extreme cases, it can cause paralysis or death if the bubbles are in the brain. Nitrogen narcosis: Deep dives can cause so much nitrogen to build up in the brain that you can become confused and act as though you’ve been drinking alcohol. … Narcosis usually happens only on dives of more than 100 feet.

Does the pressure under the water can kill the person diver?

What foe will the diver face? The answer is water pressure. The pressure of the water on a deep-diver’s body can crush him. It can easily cause death.

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. … And if a diver rises to the surface (decompresses) at the right rate, the nitrogen can slowly and safely leave the body through the lungs.

Can scuba diving damage your heart?

Breathing air under increased pressure, as you do when scuba diving, also affects your heart and circulatory system. Increased levels of oxygen cause vasoconstriction, increase your blood pressure and reduce your heart rate and heart output.

Why do deep sea divers use helium?

Function of the helium

THIS IS IMPORTANT:  Why do many diving mammals allow their lungs to collapse during the dive?

The main reason for adding helium to the breathing mix is to reduce the proportions of nitrogen and oxygen below those of air, to allow the gas mix to be breathed safely on deep dives. … A lower proportion of oxygen reduces the risk of oxygen toxicity on deep dives.

What is the deepest dive ever made?

The deepest dive on record is 1,082 feet (332 meters) set by Ahmed Gabr in 2014. That depth is the equivalent to approximately 10 NBA basketball courts aligned vertically. In terms of pressure, that’s about 485 pounds per square inch. Most people’s lungs would be crushed at that depth.
