Diagnosis And Treatment Of Diaphragmatic Dysfunction

There are many reasons for an impairment of the diaphragmatic function potentially affecting all components of the respiratory pump. Particularly, diagnosis and treatment of unilateral and bilateral phrenic nerve paralysis are challenging. Neuromuscular disorders, trauma, iatrogenic conditions, tumor compression, but also infectious and inflammatory conditions in addition to neuralgic amyotrophy and idiopathic phrenic nerve paralysis are reasons for phrenic nerve paralysis. Primarily, diagnostic procedures include the anamnesis, physical examination, blood gas analysis, lung function testing and the diagnosis of the underlying disease. In addition, specific respiratory muscle testing and respiratory imaging are available today. Current established treatment options include respiratory muscle training, long-term non-invasive ventilation and surgical diaphragm plication in selected patients.
