Together, chronic bronchitis and emphysema (CBE) ranks as one of the top five leading health problems in the United States. Few nursing interventions have been tested that improve symptom management, functional status, and quality of life. This study tested the effects of guided imagery and maximal inspiratory muscle training (MITT) in a group of 10 males and 9 females, 56-75 years old, with moderate CBE. The research tested whether the independent variables, guided imagery and MITT, have significant independent and/or interaction effects on the dependent variables functional status, fatigue, dyspnea, depression, mastery, quality of life, perceived health status, and inspiratory muscle strength. Results showed that the psychologic intervention of guided imagery significantly improved subjects' perceived quality of life. The physiologic intervention of MITT could not be tolerated by subjects, which precluded testing the effects on the dependent variables. Application of study findings to clinical practice and the need for further research are discussed.
慢性支气管炎和肺气肿（CBE）合起来是美国五大主要健康问题之一。很少有经测试能改善症状管理、功能状态和生活质量的护理干预措施。本研究对一组年龄在56至75岁之间、患有中度CBE的10名男性和9名女性测试了引导式意象和最大吸气肌训练（MITT）的效果。该研究测试了自变量引导式意象和MITT是否对因变量功能状态、疲劳、呼吸困难、抑郁、掌控感、生活质量、感知健康状态和吸气肌力量有显著的独立和/或交互作用。结果显示，引导式意象的心理干预显著改善了受试者的感知生活质量。受试者无法耐受MITT的生理干预，这使得无法测试其对因变量的影响。文中讨论了研究结果在临床实践中的应用以及进一步研究的必要性。
