- Reduced Lung Injury: HFJV minimizes lung overdistension and repetitive alveolar collapse, thus reducing the risks of barotrauma and volutrauma. - Improved Gas Exchange: By maintaining a constant mean airway pressure, HFJV enhances oxygenation and carbon dioxide elimination. - Better Secretion Clearance: The rapid, small bursts of air can help in mobilizing secretions from the smaller airways. - Enhanced Stability: HFJV provides more stable and consistent ventilation, which is crucial for critically ill neonates.
