Ventilator hyperinflation associated with flow bias optimization in the bronchial hygiene of mechanically ventilated patients

Chest physiotherapy can be used through a variety of techniques with the aim of improving bronchial hygiene in patients admitted to the intensive care unit.1 Patients are mechanically ventilated when gas exchange must be maintained, respiratory muscle work must be relieved, oxygen consumption must be reduced, or when specific therapies must be applied.2 However, these patients also risk pulmonary secretion retention, since orotracheal intubation prevents glottal closure, which is necessary for effective coughing, and reduces mucociliary transport, resulting in a predisposition to pulmonary infection.
