Question

Carbogen is:
A. Pure form of C
B. $COC{{l}_{2}}$
C. Mixture of $CO$ and $C{{O}_{2}}$
D. Mixture of ${{O}_{2}}$ and $C{{O}_{2}}$

Answer 1

Hint: Carbogen is discovered by the scientist known by the name Ladislas Meduna and also known by the discoverer name i.e. Meduna’s mixture. Carbogen is used in biology research for study in vivo oxygen and flows of carbon dioxide.

Complete step-by-step answer:
Meduna’s mixture generally have the composition of 5% carbon dioxide where carbon dioxide is represented by $C{{O}_{2}}$ and oxygen gas which was represented by ${{O}_{2}}$ and the term carbogen refers with mixture of these two gases from 1.5% to 50% of $C{{O}_{2}}$. Carbogen is very toxic in nature. This can be explained on the basis that when it is inhaled it increases the level of carbon dioxide which causes a perception. Both psychological and physiological activities occur which causes suffocation and this suffocation is due to the reason that on the brain it interprets an increase in blood carbon dioxide as a decrease in oxygen level. Inhalation of carbogen also causes the body to react in a way that it is not receiving sufficient oxygen due to which it causes toughness in breathing, increases the heart rate and cells which release alkaline buffering agents to remove carbonic acid from the bloodstream.
Hence we can say that a carbogen is a mixture of 95% oxygen and 5% carbon dioxide which further can be used as part of the early treatment of central retinal artery occlusion.

Thus option (D) is the correct answer.

Note: There are many useful properties of carbogen like in medical sciences carbogens are used in research on acute brain slices. Its use in combination with nicotinamide is also used in the treatment strategy of certain cancers.
