Abstract
Major function of the respiratory system is to provide oxygen for metabolism and remove carbon dioxide. The metabolic demands of tissues remain unfulfilled and body systems rapidly fail, without an adequate exchange of oxygen and carbon dioxide ,.When oxygenation and ventilation are inadequate Continuous Positive Airway Pressure is needed. (1-3) Neonates are child who under 28 days of age . neonates are vulnerable to respiratory problems and complications. One of the most common respiratory complications is respiratory distress syndrome . Moreover, it is a major cause of neonatal respiratory morbidity and mortality. Neonates with it can be managed by using of Continuous Positive Airway Pressure to maintain alveolar distention during spontaneous breathing, giving exogenous surfactant, mechanical ventilation and administration of surfactant therapy with rapid extubation as part of INSURE (Intubation, Surfactant, Rapid Extubation) protocols .(4) Continuous Positive Airway Pressure refers to the application of positive pressure to the airway of a spontaneously breathing neonate throughout the respiratory cycle. It is a means of providing respiratory support to neonates with either upper airway obstruction or respiratory failure. Respiratory failure constitutes either failure of ventilation or failure of lung function. It delivers oxygen concentrations and distending airway pressures via the ventilator without the hazards associated with full endotracheal intubation and mechanical ventilation.
