Long-term oxygen therapy is the single treatment proven to extend life in COPD patients with severe hypoxemia. Two landmark trials from the early 1980s showed that supplemental oxygen for at least 15 hours a day reduces mortality in patients with dangerously low blood oxygen. Those findings still anchor every major guideline, including the 2024 GOLD report. Oxygen does not help COPD patients with only moderate desaturation.<\/strong><\/p>\n

Oxygen therapy is not appropriate for every person with COPD. The evidence is specific about who benefits and who does not, and getting it wrong can worsen outcomes. This guide walks through the qualifying criteria, the trials behind them, the correct flow rates and targets, and the situations where oxygen adds burden without benefit.<\/p>\n
