Indications for oxygen therapy in COPD are guided by PaO₂, oxygen saturation, and clinical context. In this Medmastery lesson, you'll learn the indications for long-term oxygen therapy in COPD, how arterial blood gas values reflect oxygenation, and how to monitor patients after starting supplementary oxygen therapy. We cover when oxygen therapy improves outcomes and when it may not be beneficial, as well as key considerations for oxygen use during air travel.
