Research regarding dyspnea and fatigue has focused on the factors contributing to the symptoms. Physiologic factors, such as muscle use; psychological factors, such as anxiety and depression; and situational factors, such as hot weather, contribute to the symptoms of dyspnea and fatigue. Increased symptoms lead to impaired functional ability. Strategies for relief of dyspnea and fatigue can be obtained from patient report, but further research is needed to test the effectiveness of nursing interventions.
关于呼吸困难和疲劳的研究主要集中在导致这些症状的因素上。生理因素，如肌肉使用；心理因素，如焦虑和抑郁；以及情境因素，如炎热天气，都会导致呼吸困难和疲劳的症状。症状加重会导致功能能力受损。缓解呼吸困难和疲劳的策略可以从患者报告中获取，但需要进一步研究来测试护理干预措施的有效性。
