Dyspnea is caused by physical dysfunction and can induce discomfort such as exertional shortness of breath. Acute dyspnea can be servere enough to threaten life. Chronic dyspnea affects a person's daily acitvities and quality of life. This case report describes a patient admitted to an emergency room with chronic obstructive lung disease and dyspnea or hypoxia induced by eating Sauropus Androgynus to eliminate cancer toxin after breast cancer surgery and chemothrapy. Orem's self-care deficit theory was used to assess the patient's acute problems - impaired gas exchange, ineffective airway clearance, ineffective breathing pattern, and activity intolerance - and to plan wholly and partly compensatory nursing activities to deal with these problems. The theory was also used to develop patient education and coping strategies to manage dyspnea from chronic lung disease.
