Supplemental oxygen for the management of dyspnea in interstitial lung disease.

PURPOSE OF REVIEW

This article presents a summary of the evidence relating to supplemental oxygen use for the management of dyspnea in patients with interstitial lung disease (ILD).

RECENT FINDINGS

In contrast to the majority of the available literature, recent findings suggest that supplemental oxygen can significantly reduce exertional dyspnea in ILD. ILD patients' need for supplemental oxygen often surpasses the levels that the most commonly used oxygen delivery systems provide. More effective delivery of supplemental oxygen has the potential for greater relief of dyspnea. There is also evidence suggesting that indications for supplemental oxygen may differ in ILD compared with other chronic lung diseases.

SUMMARY

Large clinical trials are needed to determine if the reductions in dyspnea with supplemental oxygen observed in the laboratory setting can translate into meaningful benefits in everyday life for patients with ILD. More effective and practical oxygen delivery systems are needed. Future guidelines should consider including recommendations addressing the potential role of supplemental oxygen for mildly hypoxemic patients with ILD as well as recommendations specific to supplemental oxygen use for exercise training in ILD.
