The process of introducing oxygen into the body, typically through breathing or medical intervention. Oxygenation is essential for the proper functioning of the body’s cells and tissues and is necessary to maintain good health and prevent organ damage. Oxygenation may be impaired by a variety of factors, such as respiratory diseases, anemia, or heart failure, and can be treated with medications, oxygen therapy, or mechanical ventilation. Oxygenation is closely monitored in critical care settings, such as intensive care units, to ensure that patients are receiving enough oxygen to support vital functions.
