oxygen-enriched air

Oxygen-enriched air is a gas mixture containing a concentration of oxygen greater than the approximately 21% found in standard atmospheric air. In clinical practice, it is used to provide supplemental oxygen to patients with respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), or acute respiratory distress to maintain adequate arterial oxygen saturation. In the provided clinical context, a 30% oxygen-enriched air mixture was used as a control to evaluate the efficacy of heliox (a helium-oxygen mixture) in children hospitalized with acute severe asthma. The primary active component is oxygen, which is essential for aerobic metabolism and cellular ATP production.
