Synchronized Nasal Intermittent Positive Pressure Ventilation

Abstract

Avoiding MV is a critical goal in neonatal respiratory care. Different modes of noninvasive respiratory support beyond nasal CPAP, such as nasal intermittent positive pressure ventilation (NIPPV) and synchronized NIPPV (SNIPPV), may further reduce intubation rates. SNIPPV offers consistent benefits over nonsynchronized techniques such as a more efficient positive pressure transmission to the lung, an effective increase in transpulmonary pressure during ventilation, and a better stabilization of the chest wall during inspiration. This review discusses mechanisms of action, benefits and limitations of synchronized noninvasive ventilation, describes the different modes of synchronization, and analyzes properties and clinical results.
