心臟衰竭（Heart failure）病人的呼吸困難常源於肺部積液（Pulmonary congestion）。高坐臥姿（High-Fowler's position）能利用重力將腹部器官下移，增加橫膈膜的活動空間，從而擴大胸腔容積，減少呼吸功耗（Work of breathing），是緩解心臟衰竭病人呼吸困難最有效的體位。
Dyspnea in clients with heart failure is often caused by pulmonary congestion. High-Fowler's position uses gravity to displace the abdominal organs downward, increasing the working space of the diaphragm and thereby expanding thoracic volume and reducing the work of breathing. It is the most effective position for relieving dyspnea in clients with heart failure.
