Long-term oxygen therapy is a fundamental treatment modality for patients with chronic hypoxaemic lung disease. Typically, oxygen is administered at a constant flow rate. However, due to fluctuating activity levels, patients' oxygenation status can vary, potentially leading to oxygen desaturation and increased dyspnoea.
Emerging evidence suggests that automatic oxygen titration - a method of adjusting oxygen flow in response to current oxygen saturation - may have acute advantages over constant oxygen flow.
The primary objective of this study is to investigate the effect of automatic oxygen titration compared to prescribed constant oxygen flow rates on patients' perceived dyspnoea during exercise endurance training.
