In an atmosphere that may be oxygen-deficient, or toxic, an air supply can be carried on the back. A breathing apparatus or breathing set is equipment which allows a person to breathe in a hostile environment where breathing would otherwise be impossible, difficult, harmful, or hazardous, or assists a person to breathe.
Air is the most common and only natural breathing gas, but other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats Oxygen is the essential component for any breathing gas, at a partial pressure of between roughly 0.16 and 1.60 bar at the ambient pressure.

The weight and harness straps may limit tidal volume, ventilation rate, and oxygen consumption, and heart rate may increase in comparison with the same exercise levels without the equipment. Shoulder harness straps of heavy SCBA can reduce free motion of the thorax which affects breathing. [27]
Both rebreather and open circuit equipment have been used in this application, where either pure oxygen or supplemental oxygen is provided by the equipment. Minor leakage in either direction usually only affects efficiency and gas endurance, as the ambient air is usually only hypobaric due to low ambient pressure. [1]
In some instances, such as when you have a serious wound or infection, a higher concentration of pressurized oxygen can help you heal. This is known as hyperbaric oxygen therapy , or HBOT.
PAPRs are not effective during firefighting, in an oxygen-deficient atmosphere, or in an unknown atmosphere; in these situations a self-contained breathing apparatus or supplied-air respirator is recommended instead. [5] PAPRs have the advantage of eliminating breathing resistance caused by unpowered negative-pressure respirators such as N95 masks.
