En muchas ocasiones escuchamos la expresión "Bombona de Oxígeno", pero en el mundo del buceo es más correcto decir Botella o Tanque dependiendo del país. Mucha gente cree que el contenido de la botella es oxígeno cuando generalmente se bucea con aire. El buceo con oxígeno puro es una actividad de buceo técnico o militar que solo se realiza en determinadas circunstancias especiales y que implica unos riesgos considerables.
El aire "normal" es una mezcla de varios gases diferentes.
Cuando se modifica la mezcla de gases el resultado se define con nombres específicos referidos a la nueva mezcla que utilizará el buceador. Cada mezcla concreta requiere una planificación y cálculos propios para la inmersión y en ocasiones un equipo específico para la utilización de esa mezcla de gases respirables..
Algunas mezclas de gases utilizadas en Buceo son Nitrox, Trimix, Heliox
