A large proportion of premature infants presents with acute respiratory failure after birth and require mechanical ventilatory support. In addition to conventional mechanical ventilation, an increasing number of these infants are currently supported by newer modes including synchronized, volume targeted and noninvasive mechanical ventilation. While these new modes have improved weaning from mechanical ventilation they have not had a consistent impact on respiratory outcome or other morbidities. This is a review of the different modes of invasive and noninvasive mechanical ventilation used to support premature infants with respiratory failure.

Respiratory failure is common in the preterm infant. Support of the infant with oxygen, positive pressure, and assisted ventilation are among the commonest interventions required in neonatal care. This article is an overview of many features of respiratory care of the preterm infant, including the goals of therapy, continuous positive airways pressure (CPAP), non-invasive ventilation, various modes of ''conventional'' ventilation, high frequency ventilation and inhaled nitric oxide use. ⋯ Many prospective trials have been performed which, in general, have failed to demonstrate a significant additional benefit of any newer mode of ventilation over conventional time-cycled pressure limited ventilation. Many of the currently available modes of respiratory support have never been subjected to adequate study. Newer modes of respiratory support including such innovations as volume targeted ventilation, pressure support ventilation, and inhaled nitric oxide use in the preterm, require further investigation prior to their adoption for routine clinical use.
