Saturated percentage of oxygen (SpO2) is a measurement of oxygen levels in the blood
An oxygen-fed fire is a fire that has (most likely) pure oxygen fueling it. The air we breathe is composed of around 19% oxygen, therefore by adding more oxygen the fire will get hotter.
Fire is a process of rapid combination with oxygen.
Carbon Dioxide [CO2] controls, and can extinguish, a fire due to the fact that the addition of CO2 to the air, results in reducing the relative percentage of Oxygen [O2] to a concentration below that necessary for combustion ["burning"] to occur.
That is, what they already do. No kind of fire can burn without oxygen!
Regular air in the environment is about 21% oxygen. A fire only needs about 16% oxygen to catch and burn. See http://www.bradford-co-fla.org/scvfd/fire_information.html
The percentage of oxygen in sucrose is 51,41549 %.

At a minimum, oxygen must be what percentage of the atmosphere to sustain the burning process?
Oxygen keeps the fire going. In some cases, it can make the fire larger, depending on the amount of oxygen around the fire.
Oxygen does not distribute fire. Fire is a chemical reaction between oxygen and some flammable substance. Fire cannot burn without oxygen, and the more oxygen there is, the hotter and faster a fire will burn. More oxygen also makes it easier for materials to ignite.

Because when you blow on the coals you are adding oxygen to the fire and oxygen fuels a fire. A fire would simply go out without any oxygen. Because when you blow on the coals you are adding oxygen to the fire and oxygen fuels a fire. A fire would simply go out without any oxygen.
Fanning them brings in more oxygen. With more oxygen you get more fire.
