Artificial respiration

The process of burning of a substance in oxygen is called combustion. Hence, oxygen supports combustion. Liquefied oxygen is used as an oxidant in rocket fuel. Oxygen is used for artificial respiration in hospitals, for space missions, for sea diving, etc. Nascent oxygen [O] is a really good oxidizing agent, thus it is used for bleaching.
