The recommended therapeutic level of oxygen therapy for adults is generally considered to be between 30% and 60%. This range is optimal for treating a variety of conditions while minimizing the risk of complications such as oxygen toxicity. Oxygen therapy is often prescribed for patients with chronic obstructive pulmonary disease (COPD) or other respiratory conditions where maintaining adequate oxygenation is crucial.

Outside of this range, particularly below 30%, patients may not receive sufficient oxygen to meet their physiological needs, leading to hypoxemia. On the other hand, administering oxygen levels above 60% can increase the risk of oxygen toxicity, especially in patients with compromised respiratory function. Therefore, the range of 30% to 60% effectively balances the need for adequate oxygenation while reducing potential risks.
