Oxygen is a chemical element. Oxygen is vital for the survival of many carbon-based lifeforms, including Humans.

Oxygen is commonly found in the form of gas in the atmosphere of many Class M planets across the galaxy, although at fairly low levels. It is also found in atmospheres of Class L, Class O and Class P planets, making all capable of supporting most humanoid lifeforms. (ST reference: Star Charts)
