You indicate oxygen when writing by using the word oxygenor the symbol "O". If you are dealing with the oxygen molecule, you might write O2.
There are many ways to test for the presence of oxygen, but which is appropriate depends on whether oxygen is present as a gas or as part of a more complex compound, whether as a gas, a liquid or a solid..
A blue flame would indicate ethane burning in excess oxygen. Blue flames are typically associated with complete combustion and sufficient oxygen supply during the burning process.
An oxygen saturation below 90 percent would indicate that the individual is not getting enough oxygen into their bloodstream. This could be a sign of respiratory issues or other health problems that need immediate attention.
The subscript 2 indicates that there are two oxygen atoms bonded together in the molecule of oxygen gas (O2).
Oxygen concentration in water can be tested using a dissolved oxygen meter or a chemical test kit. The dissolved oxygen meter measures the amount of oxygen dissolved in the water, while a chemical test kit uses reagents to indicate the oxygen level based on a color change. Both methods provide an accurate assessment of oxygen concentration in water.
Doctors check oxygen levels to ensure that the body is getting enough oxygen to function properly. Low oxygen levels can indicate respiratory conditions or other health issues that may require medical attention. Monitoring oxygen levels can help doctors assess the effectiveness of treatment and determine the need for supplemental oxygen.
Oxygen help the burning.

the oxygen sensor(sensors)
a decrease in oxygen level
To indicate a presence of free residual oxygen.
a decrease in oxygen level
Oxygen sensors either work or they don't. If they don't, the check engine light will come on and indicate an oxygen sensor problem. If they're fine, none of that will happen.
O2 meaning Oxygen, the subscript 2 means that oxygen generally doesn't run around as single atoms. Instead, oxygen pairs up, with each oxygen atom bonding with another to form a molecule.
The subscript 2 indicates that there are two oxygen atoms bonded together in the molecule of oxygen gas (O2).
Fences just indicate property. Trees produce oxygen so we can breath.
It is a DOT hazmat placard meaning "compressed oxygen."
