Ans:-
Noninvasive positive-pressure ventilation (NPPV) is a form of mechanical ventilatory support delivered to patients with acute respiratory failure through a noninvasive interface. In patients with a range of etiologies for acute respiratory failure, NPPV has the potential to reduce complications and improve outcomes compared to invasive ventilation.
NPPV is a preferred method of ventilation as it eliminate the need for endotracheal intubation and its associated morbidity and mortality, including airway trauma, loss of airway defense mechanisms (ventilator-associated pneumonia), mechanical ventilation (barotrauma), and disruption of speech and swallowing.
Use of NPPV:-
Clinical scenarios in which there is evidence for the efficacy of NPPV include severe exacerbations of COPD, cardiogenic pulmonary edema, immunosuppressed patients with pulmonary infiltrates, and hypoxia; it can also be used as a bridge to extubation in COPD patients.
