What is the function of oxygen (O2) in medical therapy?

Oxygen (O2) plays a crucial role in medical therapy primarily by supporting respiratory function. It is essential for cellular respiration, a process through which cells produce energy by utilizing oxygen to convert glucose into adenosine triphosphate (ATP). Adequate oxygen levels in the body ensure that tissues and organs receive the oxygen they need to function optimally.

In various medical situations, such as chronic obstructive pulmonary disease (COPD), pneumonia, or during surgical procedures, supplemental oxygen may be administered to maintain sufficient oxygen saturation in the blood, thereby enhancing respiratory function and preventing hypoxia (a deficiency of oxygen in the tissues).

While oxygen does have additional benefits, such as potentially supporting wound healing through improved oxidative metabolism and cellular repair, its primary and most critical function in medical therapy is to support the respiratory system and ensure that cells receive the oxygen required for energy production and metabolic processes.
