Mechanical Insufflation-Exsufflation in Preventing Post Extubation Respiratory Failure in Patient With Critical Care Neuromyopathy

Respiratory failure after extubation is a relevant consequence of poor airway clearance due to respiratory muscle weakness and respiratory failure after extubation and reintubation is associated with increased morbidity and mortality. the study will evaluate the contribution of Mechanical Insufflation-Exsufflation (MI-E) in Preventing Respiratory Failure After Extubation as compared manually assisted coughing
