Oxygen was first used to manage a young patient with pneumonia in 1885, and by 1907 nasal catheter devices for oxygen delivery were introduced. [1] Since then oxygen use, its modes of administration, best oxygen prescription practices, and interfaces for oxygen administration have continued to evolve: for example, oxygen cylinder versus. piped oxygen or use of oxygen concentrators; high-flow nasal oxygen, nasal cannula, nasal prongs, nasal masks, simple face masks, rebreather/non-rebreather masks, venturi masks, masks with reservoir bag, oxygen hoods and tents, non-invasive and invasive mechanical ventilators. The way these equipment are used in pediatric and adult patients are sometimes different, such as the interfaces applicable and the rate of oxygen flow prescribed. Up to 12% of hospitalized patients may require oxygen during their admission in the hospital. [2] Every year globally, at least 1.4 million deaths occur due to the lack of supplemental oxygen therapy and inappropriate administration of oxygen. [3] In one study, 40.7% of patients had a prescription to target oxygen saturation SP02 and only 31.1% achieved their target saturation.
