What is used for respiration of sea divers?
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 gas mixture is used by divers inside the sea?
Solution: Helium is not soluble in blood even under high pressure, a mixture of 80% helium and 20% oxygen is used instead of ordinary air by sea divers for respiration.
Which inert metal is used for respiration of sea divers along with oxygen?
Well, oxygen does not dissolve directly into blood under high pressure existing in the deep sea, hence inert gas like helium is mixed with oxygen during deep sea diving.
Which of the following is used for respiration of C drive?
An oxygen-helium mixure is used 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.
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. … Helium has very little narcotic effect. A lower proportion of oxygen reduces the risk of oxygen toxicity on deep dives.
Which of the following mixture of gases is used by the drivers in the sea?
That is why surface equipment is provided to the sea drivers. The breathing gas mixture is supplied from a face mask. Thus the gas mixture is heliox which is a mixture of helium and oxygen. The proportion of oxygen in the gas mixture depends upon the depth of the drive plan which is approximately ten percentages.
What problem could happen if deep sea divers use pure oxygen?
Divers (and diving mammals such as whales and seals) are entirely dependent on the oxygen carried in the air in their lungs or their gas supply. Divers also have a paradoxical problem with oxygen. At higher partial pressures oxygen causes acute toxicity leading to convulsions.
Which inert gas is used by deep sea divers for breathing?
Neon (Ne) is an inert gas sometimes used in deep commercial diving but is very expensive. Like helium, it is less narcotic than nitrogen, but unlike helium, it does not distort the diver’s voice. Compared to helium, neon has superior thermal insulating properties.
Why deep sea divers do not use compressed air?
Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues. … But if a diver rises too quickly, the nitrogen forms bubbles in the body. This can cause tissue and nerve damage.
