Dyspnea is a common and devastating symptom of life-threatening disease. Approximately 90% of non-small cell lung cancer patients experience moderate to severe dyspnea by death. Currently, the pathology is ill-defined and measurement of this subjective symptom is imprecise. ⋯ This article outlines the current state of knowledge and standards of care for palliative interventions in dyspnea. These include nonpharmacologic interventions, oxygen supplementation, and medications. Further research is needed to clarify the role of each and to develop better pathophysiologic understanding.
