The experience of episodic breathlessness from the perspective of informal caregivers: a qualitative interview study.

Background: Episodic breathlessness is a common form of chronic breathlessness that is highly distressing for patients with diseases such as chronic obstructive pulmonary disease (COPD) and lung cancer in advanced stages. Little is known about the experiences of informal caregivers who care for patients with episodic breathlessness. The present study aims to explore and describe the experiences and coping strategies of informal caregivers who deal with this challenging condition.
