What condition does orthopnea describe?

Orthopnea specifically refers to difficulty breathing when lying flat. It commonly occurs in individuals with certain medical conditions, such as congestive heart failure, where the position of the body affects lung capacity and overall breathing efficiency. Patients often find relief by sitting or standing up, as these positions can help reduce the pressure on the lungs and improve airflow.

The understanding of orthopnea is crucial in evaluating patients with respiratory issues, particularly those related to cardiac function. Recognizing this condition allows healthcare providers to implement appropriate interventions, such as elevating the head during sleep or assessing the need for diuretics in heart failure patients.
