Which mixture is used for respiration by deep sea?
oxygen- helium mixture An oxygen- helium mixture is used for artificial respiration in deep sea diving instead of air because nitrogen present in air dissolves in blood under high pressure when sea diver goes into deep sea.
Which noble gas is used along with oxygen by deep sea drivers?
helium We can understand from the above discussion that deep-sea divers use a mixture of helium and oxygen. Therefore, the correct answer is option (A) helium-oxygen. Note: We know that air is a mixture of 21% oxygen, 78% nitrogen and 1% of other noble gases.
Which of the following gases along with oxygen are given to scuba divers?
The mixture of gases used by deep-sea divers is helium-oxygen.
Which of the following gaseous mixture is used by sea divers in deep sea diving?
Solution : Deep sea divers use mixture of helium -oxygen of its very low solubility in blood .
Which of the following is used for the respiration of sea divers a mixture of He and o₂ C mixture of Ar and o₂ B mixture of Ne and o₂ D mixture of He o₂ and AR?
Oxygen and Helium are used for respiration by the Sea divers. Helium gets mixed with the oxygen in order to reduce the proportions of Nitrogen and Oxygen below those of air. Such low nitrogen proportion is required to reduce the nitrogen narcosis.
Why is oxygen mixed with helium used by sea divers?
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 nitrogen is required to reduce nitrogen narcosis and other physiological effects of the gas at depth.
Which of the following mixture is used for the respiration of sea divers a he and o2 B NE and o2 C Ar and o2 D He o2 and Ar?
Oxygen and Helium are used for respiration by the Sea divers. Helium gets mixed with the oxygen in order to reduce the proportions of Nitrogen and Oxygen below those of air. Such low nitrogen proportion is required to reduce the nitrogen narcosis.
Why mixture of He and o2 is used by sea divers?
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 nitrogen is required to reduce nitrogen narcosis and other physiological effects of the gas at depth.
What gas is used for scuba diving?
The most commonly used gas blend for sport or recreational diving is Nitrox up to 40% oxygen. Technical divers often use Nitrox gas mixes with higher level of oxygen up to 100% to accelerate decompression. More advanced technical divers use Trimix so as to be able to dive safely to depths greater than 60 metres.
What is the gas mixture in a scuba tank?
A common mixture is 21/35, which has 21 percent oxygen, 35 percent helium and 44 percent nitrogen. Another common mixture is 18/45, with 18 percent oxygen and 45 percent helium. These mixtures allow technical divers to hang around at up to 197 feet (60 m) — and actually remember their dive.
Why is helium used in deep sea diving?
Helium is a very light inert gas. It is used by technical divers to reduce narcosis when diving at deeper depths. With normal air (21% oxygen/ 79% Nitrogen) nitrogen narcosis becomes an issue at these depths. To reduces the effects of the narcosis we replace some of nitrogen found in air with some helium.
Why do deep-sea divers use helium and oxygen?
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 nitrogen is required to reduce nitrogen narcosis and other physiological effects of the gas at depth.
What gas is used for diving?
Hydrox, a gas mixture of hydrogen and oxygen, is used as a breathing gas in very deep diving. Neox (also called neonox) is a mixture of oxygen and neon sometimes employed in deep commercial diving.
Why do deep-sea divers breathe A mixture of helium and oxygen quizlet?
Why do deep-sea divers breathe a mixture of helium and oxygen? Too much oxygen can cause physiological problems. Scuba divers breathe pressurized air. This elevated partial pressure of oxygen rasies the density of oxtgen molecuels in the lungs, resulting in a higher concentration of oxtgen in body tissues.
Which of the following is used for the respiration of sea divers a mixture of He and o₂ B mixture of Ne and o₂?
Helium gets mixed with the oxygen Inorder to reduce the proportions of nitrogen and oxygen below those of air. Such low nitrogen proportion is required to reduce the nitrogen narcosis. Oxygen and Helium are used for respiration of sea drivers. So, a) mixture of He and O2 is correct.
Which of the following mixture of gases is used in cylinder by scuba divers for breathing?
The most commonly used mixture is nitrox, also referred to as Enriched Air Nitrox (EAN), which is air with extra oxygen, often with 32% or 36% oxygen, and thus less nitrogen, reducing the risk of decompression sickness or allowing longer exposure to the same pressure for equal risk.
Why is nitrogen used in scuba diving?
When you scuba dive, the longer you stay under the water (bottom time), the more nitrogen your body absorbs. If divers absorb too much nitrogen in their blood stream, they develop a condition known as “the bends” (also known as decompression sickness).
Why do divers breathe nitrogen?
Advantages of keeping some nitrogen in the mix Retaining nitrogen in trimix can contribute to the prevention of High Pressure Nervous Syndrome, a problem that can occur when breathing heliox at depths beyond about 130 metres (430 ft).
Why do divers use nitrogen?
Use of these gases is generally intended to improve overall safety of the planned dive, by reducing the risk of decompression sickness and/or nitrogen narcosis, and may improve ease of breathing.
Why helium is used in deep water instead of nitrogen?
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 nitrogen is required to reduce nitrogen narcosis and other physiological effects of the gas at depth.
Why deep sea divers breathe a mixture of helium and oxygen?
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 nitrogen is required to reduce nitrogen narcosis and other physiological effects of the gas at depth.
When divers breathe air at increased pressures the amount of nitrogen dissolved in the blood?
According to Henry's theorem, a gas's solubility increases as pressure rises. More nitrogen is dissolved in the person's blood as a result of the increased pressure, resulting in nitrogen narcosis. By ascending to lower pressures, the diver will reverse the result.
Which of the following mixture is used for the respiration of sea divers a he and O2 B NE and O2 C Ar and O2 D He O2 and Ar?
Oxygen and Helium are used for respiration by the Sea divers. Helium gets mixed with the oxygen in order to reduce the proportions of Nitrogen and Oxygen below those of air. Such low nitrogen proportion is required to reduce the nitrogen narcosis.
Which of the following is used for the respiration of sea Devers a mixture of He and O2 B mixture of Ne and O2 C mixture of Ar and O2 D mixture of He O2 and Ar?

What is the air mixture in a scuba tank?
These common diving breathing gases are used: Air is a mixture of 21% oxygen, 78% nitrogen, and approximately 1% other trace gases, primarily argon; to simplify calculations this last 1% is usually treated as if it were nitrogen.
Why do deep sea divers use helium instead of nitrogen?
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 nitrogen is required to reduce nitrogen narcosis and other physiological effects of the gas at depth.
Why helium is used for respiration in deep water instead of nitrogen?
Helium is substituted for nitrogen in the air used by deep sea divers for breathing because Helium is sparingly less soluble in blood, unlike Nitrogen which is more soluble in blood.
Which gas is used in deep water?
Hydrox, a gas mixture of hydrogen and oxygen, is used as a breathing gas in very deep diving.
