Oxygen Sucks Customer Reviews and Feedback
Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. After hydrogen and helium, oxygen is the third-most abundant element in the universe by mass.
Oxygen can be really harmful over a period of time, causing overproduction of free radicals in the lungs, killing lung tissue, and leaving permanent lung damage, according to an article published by thebetteroxygenmask.com
"There is still debate as to how much oxygen is too much oxygen. We do know, however, high concentrations of oxygen over a period of time cause an overproduction of free radicals in the lungs. If unchecked, these radicals can severely damage or kill lung tissue. If left for a prolonged period of time the patient can suffer permanent lung damage."
