Chronic obstructive pulmonary disease is a progressive and debilitating disease that is typically diagnosed only after a long period of gradual worsening. Dyspnea is the symptom that most often interferes with the execution of professional, family, social and daily-life activities of patients with chronic obstructive pulmonary disease. Such limitations can lead to a sedentary lifestyle and worsen overall quality of life. ⋯ Even simple tasks can result in high oxygen consumption and minute ventilation, which accounts for the sensation of dyspnea reported by the patients. In view of these facts, it is appropriate to evaluate the impact that such incapacity has on daily life in patients with chronic obstructive pulmonary disease. Techniques of energy conservation that can be used as tools to minimize the discomfort of such patients are herein discussed, and those considered most appropriate are highlighted.
