呼吸困難是因生理功能障礙引起呼吸費力、呼吸急促之不適感覺，緊急者有生命危險，慢性者有日常活動功能干擾及生活品質下降之影響。本報告之個案曾經罹患乳癌手術及化學治療，聽信民間謠傅減肥菜之排除癌症毒素功效，飲用後半年出現阻塞性肺疾病，呼吸因難，血氧過低入院治療，筆者應用Orem自我照顧缺失理論提供護理服務，針對個案自我照顧缺失的問題應用完全及部份代償之護理措施，不僅對此不可逆阻塞性肺疾病急性發作給予生理上的照護，同時支持教育性護理措施也協助個案發展適應策略以因應慢性肺疾病長期呼吸困難所帶來的困擾。

Dyspnea is caused by physical dysfunction and can induce discomfort such as exertional shortness of breath. Acute dyspnea can be severe enough to threaten life. Chronic dyspnea affects a person's daily activities 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 chemotherapy. 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.
