Currently, pneumotachography is the most commonly utilized bedside technology. Tidal volumes (V t) can be measured continuously by monitoring airflow signals of assisted ventilation. Understanding of physiologic determinants of tidal volume allow for optimal tidal volume delivery by using minimal pressures to achieve desired carbon dioxide exchange without air-trapping. This biotrauma triggers a cascade of proinflammatory responses associated with an increased occurrence of bronchopulmonary dysplasia (BPD). In uniquely vulnerable preterm infants, excessive tidal volume, volutrauma, is a significant contributor to ventilator-induced lung injury (VILI).
Neonatal tidal volume breathing is fundamental to gas exchange and ventilatory support after birth.
