Respiratory muscle weakness is an uncommon cause of chronic respiratory failure and a rare cause of cor pulmonale. The problem may not be apparent unless specific physical signs are sought or appropriate investigations performed. We present three patients who presented diagnostic difficulty for prolonged periods until the presence of respiratory muscle weakness was considered. Once the diagnosis was established treatment with nocturnal nasal intermittent positive pressure ventilation produced a dramatic improvement in symptoms and allowed a return to a near normal lifestyle.
呼吸肌无力是慢性呼吸衰竭的罕见病因，也是肺心病的罕见病因。除非进行特定的体格检查或适当的检查，否则这个问题可能并不明显。我们报告了三名患者，他们在很长一段时间内诊断困难，直到考虑到存在呼吸肌无力。一旦确诊，夜间经鼻间歇正压通气治疗使症状显著改善，并使患者能够恢复接近正常的生活方式。
