oxygen level

Respiratory saturation reading

Oxygen level is the concentration of oxygen in a substance or environment, typically expressed as a percentage or partial pressure.

In medical contexts, it usually refers to blood oxygen saturation—how much oxygen red blood cells are carrying: Her oxygen level dropped dangerously low.

Environmental oxygen levels matter for altitude sickness, diving, and fire safety.
