A 49-year-old woman presented with idiopathic bilateral diaphragmatic
paralysis. The patient benefited from bilevel intermittent positive ai
rway pressure-type assisted ventilation with rapid, excellent and long
-lasting results. This case emphasizes the need for correct diagnosis
and therapeutic management, particularly with a bilevel intermittent p
ositive airway pressure-type home ventilation technique, in idiopathic
bilateral diaphragmatic paralysis.
